I completed the main setup for Rex montages. The Deinosuchus needs some special treatment due to its morph target setup and animations. The core systems for Rex and Trike are now mostly finished, with the Crush ability undergoing some bug-fixing, leaving sparring as the final step for full release.

I have been working on a variety of systems. There are now interactive foliage sounds which trigger when animals move through larger vegetation. This really helps communicate dinosaur activity to players that they were missing before just because they couldn’t see one another.

Besides that, I also have been working on the Allosaurus, primarily it´s special ability that allows them to pull a victim down or pull themselves on top of it, depending on victim size. The main setup for this is done, allowing for balance to be set up before we move into bugfixes and visuals.

And, some more changes have been done server side to improve its stability and performance with good results so far. Plus several bug fixes in general. See you!


I spent much of the month working on the triceratops, fixing various issues that came up and also making some improvements to sparring in general. The sidestep in particular is more responsive and it is now easier to follow up with other abilities or to disengage. The thrash attack is now activated by double-clicking LMB and can be done from all forms of locomotion. It might take some getting used to at first, but it provides far better control.

I also made various improvements and fixes here and there. Many of the dinosaurs are getting fixed to feel more responsive from how quickly they can move out of their resting states to movements after using certain attacks. I also made the camera movement smoother when sitting down or standing up. Finally I also worked a bit on the hypsilophodon’s climbing feature.


This month has been all about the tunnels, aka GUTS. Who would’ve guessed? This month I’ve built the whole construction to be able to be used mostly with simplicity, while keeping the amount of pieces as low as it can get, to not introduce any unnecessary complexity where we in fact don’t need any.

This does not mean that the tunnels are simple in nature, but rather than its assembly has been brought down to be as simple as it could to assemble, giving Jace, our level designer, a lot of room and freedom to maneuver, while giving him ample time to decorate the actual interior of the GUTS connections.

These models are for now called “corrective pieces” as they make sure that we allow full scale of verticality and horizontality during building, such as various pieces of staircase, diagonal rooms, ramps, etc.

Alongside those, I’ve made short pieces of the tunnels to allow very interesting mixing such as 2 tunnels or even X tunnels side by side, without breaking the grid.

Very simple tunnel layout made in less that 20 min with our pieces:
Some Diagonal Pieces:
New Elevator lobby piece for the tunnels:
And finally I’ve begun work on a massive new HUB which isn’t the industrial one, who, I won’t for now disclose much, and will sadly have to wait for the next dev blog.
I will leave with this though:
That is it for me this month!


This month I have been finishing off Triceratops vocal call sounds, firstly working on final adjustments to the design of the adult vocal sounds and then working on the mixdown for each and ensuring that each call sounds weighty and powerful at both full and out of breath stages.

I have completed both the subadult and juvenile vocals as well, making sure each vocal was both a similar length to match the new animations and the adult vocal as well as carrying the aesthetic design of the adult vocals but reflecting the growth stage for each.

I also finalised the implementation of the vocals, making sure that the vocals both crossfade cleanly across all the growth stages and that pitch modulation for each vocal of the individual growth stages is manipulated so that the transition at each individual growth value is clean, clear and sounds appropriate.

Finally I have now moved on to working on the rest of Trike’s vocal suite starting with its directional attack sounds.Looking forward to working on the rest of its suite and bringing the Trike to life.


This will be short and sweet since the hordetest has been dominating our focus largely. Thanks again for those of you that have participated. We’ve been spending time bug fixing and keeping a watchful eye on how the triceratops is performing. There needs to be some adjustments here and there, like with nightvision but largely with triceratops we are pretty satisfied with how the creature landed. However there is still more work to be done to ensure the triceratops and tyrannosaurus are able to have their epic showdown in a fashion befitting two of the most popular dinosaurs of all time.

So, while all that bug smashing stuff is happening, the rest of the team is working on other things. From knocking out skins for Acrocanthosaurus and Suchomimus, to elder related work on Spinosaurus, Quetzalcoatlus and Parasaurolophus. I have been doing some animation prep work for things like baryonyx’s defensive stance, avaceratops attacks, hypsilophodon climb finalization, dryosaurus springboarding, kentrosaurus defensive stance, parasaurolophus revisiting, omniraptor crouch pursuit, charge jump and more. Austroraptor is rebelling a little bit but nothing we can’t handle. All in all we’re going to be touching up a fair amount of the current roster so they can all nestle into their niches and mechanics for the foreseeable future.

That’s pretty much it for this month. Bugs, changes, tweaks and the steady standard. I’ll drop some pics and clips though. See ya!

It’s been another busy month with a primary focus on the new playables like the Tyrannosaurus Rex, Triceratops and Allosaurus. The T-Rex’s signature mechanic, Crush, is nearing completion, with only a few animation adjustments left to finalize.

Another mechanic for sub-adult and older tyrannosaurs is a short, but effective speed burst to aid in ambushes. It has worked fairly well during internal tests, but we’ll be continuing to monitor its impact after release. We may also extend this ability to other animals, depending on its performance and balance, otherwise removed if deemed problematic.

In addition, I’ll soon be wrapping up the Throw ability for the T-Rex. This is primarily a gore-focused mechanic rather than a damage-dealing one, allowing players to throw corpses or enemies that are already guaranteed to die once released, which is an extension of the Crush ability but for smaller prey.

I also worked on Spawn Codes, which allows you to invite your friends to spawn alongside you. This feature is already available in the ongoing Hordetest. The Cannibalistic mutation now comes with unique skin colors. Once the mutation is active, your chosen skin will be overridden by a specific color set that indicates to others your dietary preference.

Besides that I also added an option to swap asset sex from within the skin creator panel, which has been a long requested QoL change that became necessary with the introduction of spawn codes.

Thermals and Slipstreams are also finalized and are exclusive to flying animals. While these systems could have even more uses in future, we currently have no plans beyond their current intended functionality.

To wrap things up, I’ve implemented new admin commands, made various improvements and fixes to pounce (including collision and animations), addressed animation issues for Triceratops, and resolved various other bugs across different areas.

See you next time!


Hello! Most of the last month I've been working on AI which includes Carnotaurus, Tenontosaurus, Omniraptor, Dryosaurus and Deer along with a new behaviour debugging tool that works with the new AI logic system. I also spent some time working on an extension of the engines navigation system for pathing around water and dynamic obstacles.

Bug fixing for the Psittacosaurus and its object carrying feature. I’ve been prototyping a new system for grass trails which are basically just flattened or grass being pushed down as characters walk through it. There are lots of challenges with this in terms of replication, culling and performance. I'm looking forward to finishing the production version of that soon.

I’ve also been working on the new replay filters which are designed for replays to give a more cinematic or immersive feeling to replays. Reworked some of the audio for animals to have “attenuation” meaning instead of fixed distances for an animal to “hear” a player the perception adheres to the sounds actual attenuation, This also comes with the advantage of more granular control of when and how audio is played. Investigations are also underway for various issues and server performance on hordetesting.

I’ve also added a small QoL change that's worth mentioning, If you are disconnected for some reason or the game crashes you can now reconnect without needing to queue again. This is entirely dependent on how long you take to restart the game, if the game detects an active session when you get back to the main menu it will prompt you to reconnect.



This month I’m happy to reveal our next, massive structure on the island. The original and monstrous DTA (Dinosaur Transportation Area). While it's been a large undertaking, it is now ready to be used in-game, and it features almost twice the size of our regular dock DTA. It is meant to house the largest of the dinosaurs for further transportation and has massive fences and sally ports to keep everything contained.

Next up, I’ve been working hard with Jace on some minor river fixes that came with the new waterfall area, however, most importantly I was and will be on the GUTS assembly for the interior to finally bring it full circle to life. I won’t go too much into detail right now but rather give you really nice snippets of what we are building here, in which all of the areas and hallways will connect to various hubs and GUTS parts.

That is all for this month, I hope you enjoy the snippets. Until next time.


At the beginning of this month after a bit of time away at the end of January I finally finished off Maiasaura with a new pinned vocalisation that better shows the distress with more visceral screams throughout the animation.

I spent some time readjusting footstep attenuation ranges to travel to more appropriate ranges for each size and speed, giving crouch and sprint their own ranges opposed to sharing with walk and trot respectively. The ranges have been reduced slightly to work together with the introduction of new audio for moving through foliage. With the reduced footstep ranges this will give more opportunity for stealth play to be a viable tactic, if you are considering how you approach. The foliage sounds will have a range that carries further so you will need to be aware of how much noise you and others around you are producing in highly vegetated areas. This will also play nicely into the Gallimimus’ paranoia mechanic so it is harder to tell whether the sounds you are hearing are real or not.
After recording a large amount of foliage source material I have created an audio system that dynamically changes the sound of foliage based on the size and speed of your Dinosaur, small crouching dinosaurs will produce a light rustle of leaves whereas large sprinting dinosaurs will create a cacophony of snapping stems and thick swooshing. The snapping sounds will also change based on whether the plant you are moving through has a wood or plant based trunk or if it even has a trunk at all.

For the rest of the month I have been working on Triceratops. Starting with adding in the legacy vocal call sounds as placeholder so it is not silent until its new vocals are complete, as well as adding footstep sounds to its basic locomotion animations. Next, I did a preliminary pass on animations adding more footsteps where necessary as well as foley sounds for all animations. As vocal sounds are introduced for all the various mechanics and animations these foley sounds will be methodically tightened up in terms of sound quality, volume, sync etc.

I have also been working on new designs for its adult stages’ calls maintaining the essence of the legacy calls but giving them the usual glow up. However, some changes are being made to the overall design principle, giving the adult stage an emphasis on a booming quality to really sell its stature and power and keeping the higher elements of the original sounds for its subadult phase. I’m looking forward to hearing these out on The Isle!


I’ve been busy with a few things lately. Outside of some icon and logo edits or variations, the modeling/concept team and I have been chipping away at the elder designs for our dinosaur roster, trying to make sure each one has its own little characteristics so not all the elders age in exactly the same way.

Outside of the dinosaurs, I’ve gotten a chance to tackle updating one of our older legacy concepts; the tissoplastic reaper!

This was one of my favourite concepts from before I joined the team, so I very much wanted to keep the overall character of the reaper, with its needle laden skin and bat-like appearance.

One feature that didn’t quite make the cut though were the scythe claws that used to protrude from the side of the hands. While it did make for a neat silhouette, its existence just started to look impractical, particularly from a mobility standpoint where an oversized spike coming out of the hand is simply begging to get caught on everything in any remotely tight space. Besides, with talon-like claws and forearms loaded with thorns, it has everything it needs to rip its prey to shreds if it gets the jump on you.

I did try drawing up a smaller “collapsible” version of the scythe claw, but it remains to be seen if it will make the cut.

Scythe-claw aside, we didn’t want to just take away a feature from the reaper without putting something back. After some thought, the idea of adding a membrane to the underarm was pitched with the idea that we might try giving it a gliding ability to allow the reaper more range for surprise attacks from high up places.


I hope that you are all enjoying the first iteration of the spawn code system, which was proving to be a bit of a pain to get to work initially, but it seems it’s finally almost there. During this time, we’ve been looking at feedback on how this mechanic can be improved and we’re constantly making changes to it. Speaking of, just recently Filipe made it so that Stream Mode hides the spawn codes from being visible (while still able to be copied), which should hopefully assist your favourite streamers against those pesky snipers!

QA have spent the majority of this month with a large focus on some of our most anticipated playables to date, the Tyrannosaurus and Triceratops are very rapidly becoming ready to be moved over to our horde testing branch. As you may have heard, we will be staggering the introduction of these characters, first testing the Triceratops on its own, then the Tyrannosaurus on its own, before finally testing them simultaneously. The reason for the staggered approach is to have our full-focus on one playable at a time, increasing the number of people testing the individual species, resulting in more bugs caught and for ease of balancing against the rest of the roster. Here’s just a handful of issues that we ran into:


Troodon causing Rex to grow even larger:
Rex taking head fracture to the next level:
Rex turning other characters into a skipping rope:
Omniraptors shrugging off Triceratops horns:
Triceratops abomination:
Thank you to all of those that are participating in the latest horde test, reporting issues using our community bug form[docs.google.com], and continuing to assist us with making the experience as smooth as possible - we couldn’t do it without you. Here are a couple of highlights from the community reports:

Gallimimus turning upside down when falling with a fractured leg:
Bouncy waterfalls:
So there’s Hordetesting going on this month. Thank you to everyone that has participated. There’s some additional content that will eventually make it into hordetesting over time but for now we appreciate your feedback.

We’ve been making some tweaks to playables across the board that will slowly start appearing over time. Some changes from mild to wild, in no particular order for ceratosaurus, herrerasaurus, omniraptor, troodon, maiasaura and others. All of that is alongside the trike and rex sparring which is looking quite nice. Hopefully we can get some visuals going on that for you guys. We’re trying to preserve the ability for the trike to also be able to spar with the diablo at various lifestages even if at certain sizes it becomes no contest. But until those sizes, who “wins” is up in the air.

I’m very pleased with the work our animation team has been churning out. Trike and Rex have some filler animations I’ve been creating as testing dictates. The visuals we want to use and the visuals we need to use are not always the same thing unfortunately, so I have to make sure the visuals are lining up with the mechanics as best they can and within time constraints, which takes a bit of trial and error. For instance, what animations the creatures transition into and out of based on what abilities they used prior and which they use next. It’s a whole thing.

The rest of the animation team has been cooking with gas. Not only have they knocked out their contributions for tyrannosaurus, triceratops, allosaurus, austroraptor and kentrosaurus but they have also made quick work of a new roster wide feature that will be coming soon enough. Provided it works the way we want it to. Should help some of the tricky terrain less tricky. If that weren’t enough, they have also begun animating the baryonyx which I’m so excited to see come to life.

Do keep in mind though that animation is but one rung on the ladder of completion. So being animation complete is not the same as being production complete and not indicative of a release. Skin, material, tech animation, sound, programming and balance setup all contribute heavily to the completion of a playable. So lots of support for the other departments as they are all important.

Speaking of departments, I’ve got a few things I can share:

Hope you all had a great holiday season with your loved ones. After spending time with family and friends it’s time to get back to work.

The main ability of the allosaurus has received more attention this month. While the main code is the same as some existing mechanics, visually the allosaurus looks very different when performing the action, so some adjustments are specifically made to accommodate this. We are in the phase of getting all the animations playing as they should and then we can move into QA testing and balancing.

The tyrannosaurus also required some additional work. There was some experimentation with mechanics to better balance its movement and hunting capabilities during its different life stages. Keep in mind these are additional mechanics focused on balancing; the pre-existing ones you already know about are unchanged.

Migration and Patrol Zones now support custom shapes, whereas previously they could only be made with generic ones such as Box or Sphere. Now those areas can be customized to just about any shape. This is very useful since most biomes and areas of the map will never be accurate using sphere or box shapes. This will help in making the areas more accurate to the map landscape overall while interacting with the migrations, but also allows all plants to spawn more accurately, avoiding edge cases with plants and trees spawning in areas of no traffic or even unreachable locations.

Lastly, the “Friend Spawn Code” is under testing with QA. I believe the system is close to fully functional, but we are also working on resolving a few possible exploits before it goes out.

See you guys next time!


I’ve been spending pretty much all of January going through the upcoming roster to make sure everyone has their bone meshes and rib meat. And then horribly mutilating them to do the gore morphs.

It’s an Allosaurus so he’ll walk it off and be just fine.

I’ve also started doing the Elder morphs, which have been a long time coming now so you can all reenact the closing scene of Saving Private Ryan together.

Lastly, with animation well under way for Kentrosaurus among the animation team, I’ve started rigging up the Baryonyx.


This month I’ve been focused on making the final assets for the GUTS, and have been working on making smaller kits that fill out some coastal locations.

The GUTS received further additions this month with additional entry types. It features a sally port, a small control center for operating the doors and the security system.

In addition, some love was shown to our older parts of the kit and the new enclosure fence received some much needed 45 inward and outward fencing to make it feel more natural and assist in building.

And finally to top it all off, I’ve been working on the holding pen for sauropods and strains. I’ll hold off on showing until I’m happy with it, but when it’s ready I’ll have it passed through Phase Three. It’s a hulking structure that feels like the interior area could be its own level. And it’s almost, if not, twice the size of the DTA.


It’s good to be back! I took some time over the holiday to get into some playtesting on the official servers to identify many of the current major issues in the game. While this is far from a complete list, here’s a quick rundown of the issues I will be looking to have addressed over the next few patches:

• Plants causing input lockups sometimes when eating them.
  
• Plants disappearing but still being scentable.
  
• Persistent rain sounds, despite it being clear weather.
  
• General audio choppiness.
  
• Omniraptors being kicked when dismounting from a pounce. (Fixed as of the latest patch!)
  
• Grappled characters being able to break out from the pounce, even when pinned.
  
• Cannibal mutation not appearing despite conditions being met.
  
• Fish AI not spawning in certain rivers/lakes.
  
• Various replay issues. Timer not going down, replay not being visible, etc.
  
• DLSS screen tearing.
  
• Dilophosaurus hallucinations sometimes being invisible.

Be sure to send in a bug report if you believe I’m missing anything substantial, but the above is what stood out to me the most.

QA has hit the ground running upon returning from the holidays, focused primarily on all of the community bug reports that we amassed during the break; we had over 600 reports to sift through! So, thanks to those of you that took the extra time to submit a bug report, they’ve been a great help as always.

As well as looking at the community reports, we’ve been busy running into our own issues, such as the beipiaosaurus becoming a little too enthusiastic when dolphin diving:

We experienced some difficulty testing a corpse related bug recently due to a certain AI animal. It should be known that while the psittacosaurus is meant to carry small corpses of comparable size, we hadn’t intended it to take ceratosaurus’ corpse bully niche:

Hopefully it doesn’t start chuffing!

Then there’s whatever is happening with this poor soul:

As Filipe mentioned, we’ve just been given access to the new Spawn Code system which is making great progress with each testing session. Being able to spawn in with your friends will be a huge benefit to players that want to group up, while still not disrupting the randomness of spawning that we want to retain. It’s a very simple system that works as follows:

1. The player joins a server, selects their species, and navigates to their group menu upon spawning.
   
2. On the group menu, the player will find a “Spawn Code” which lasts for 5 minutes. They can copy it and send it to their friends.
   
3. A friend can navigate to the “Eggs and Spawn Codes” menu and input the code. Upon being accepted by the code owner, the friend will then be able to customize their own character’s skin, before spawning in near the player that sent the code.

The following was taken from the latest QA build, which is still heavily WIP:

Hope you all have had a decent start to the new year. While this month and last month were pretty short, the amount of stuff we’ve been up to is anything but minimal. I spent most of January getting back on the saddle checking in with each department to reassess their needs and having a bunch of meetings on what our first quarter will look like. Some topics of conversation range from rounding out Elder mechanics, spawn codes and more.

We’ve been doing a fair bit of QoL changes and at last returning to work on some of our shelved features for some of the existing dinosaurs, varying in degree. The hypsi and its ability to move about the treetops is a good example. The herrera’s climbing being a bit more dynamic, troodon getting some assistance performing its role etc. I had a bit of time on my hands so I was able to scrounge up some clips. Everything is subject to change of course.

The rex, trike, allo, austro and kentro are all looking pretty good and patiently awaiting their individual debuts. We’re pushing towards a hordetest fairly soon to get some much needed changes in your hands and if luck be on our side, maybe a bit more. The rex and trike need a handful of animations related to sparring before they will be fully ready for testing, the allosaurus needs some setting up and mechanic refinement while the austro and kentro await setup.

If all that weren’t enough, the baryonyx is next. Animation work never ceases.

We also have some minor features that we plan to implement to help the entire roster navigate precarious terrain with more ease as well as a new feature that should allow certain non jumping carnivores the ability to be proficient under more circumstances.

That’s all for now. See you in the hordetest!

Hey Islanders, while there will not be a DevBlog this holiday season, we do have patch notes!

Thank you to everyone that participated in our recent Hordetest. It’s been an action-packed year and we’re all excited for what 2025 has in store for The Isle. A new patch is now available on the EVRIMA Public Branch. Happy Holidays everyone!

At the beginning of this month, I focused on fixing crashes and various bugs for the latest public patch while simultaneously working on the Allosaurus and its unique mechanics. Most of its basic systems are already functional, though some key animations, particularly those tied to its special ability, are still in production.

We also made notable progress on the Tyrannosaurus, mostly visual fixes and enhancements. This includes smoother animation blending and better integration with its mechanics to help translate visuals due to its size.

Additionally, fruit trees themselves will now be edible, not just their individual fruits. This provides a more practical food source for larger creatures at the cost. Consuming the tree significantly reduces future food availability, as a tree is necessary for fruit to grow back.

Finally, I added the gastrolith system. All playables can now consume gastroliths, which decrease the food contents of your stomach at a faster rate so that you can better manage your nutrition and diet combinations.


This month my main focus was the maiasaura. The animal is getting close to completion and it’s in full QA testing now, so new issues kept popping up for me to fix. Luckily nothing major was broken and we were also able to set up its stats now that everything is in place. Overall I feel satisfied with how the dinosaur turned out. Originally I was a bit wary of how we were going to support the two different stances, but it worked out quite well.

When not working on the maiasaura or bug fixes I had some time to start looking at my next task, which involves the pteranodon. I always enjoy working on the more agile animals, so I was quite excited about it. This won’t be part of the upcoming update as it’s in early stages, but you can expect some nice little additions.


This month I’ve been making my way through a large majority of adult Maia’s supplementary vocal sounds with only its pounced, pinned, blind and female court vocal sounds remaining. After these are complete, I will be altering these vocals for its juvenile stage. I’ve also done another pass on the adult animations adding short vocal sounds where necessary as well as more breath and foley sounds.

I’ve overhauled and simplified the way we handle reverb for calls at a distance, providing more accurate control on the amount of reverb the sound is sent to over distance. Within this overhaul I made changes to the reverb effect, adjusting decay rates, dampening etc. affecting how it sounds for each size category to be more appropriate and more importantly prominent. I also added an additional send to a multitap delay effect to simulate echo as it gets further away. The combination of all these changes should have a significant effect on making vocals more accurate and help the player identify the distance from a sound source.

I’ve also replaced the distant stomp layer of large footstep sounds and made some adjustments to attenuation and volume balance for the large footsteps.


This month has been all about the guts. Well not those guts, but the G.U.T.S. Most of my month has been focusing on the new shader Ikarop did and putting it to its true test with a big variation of materials, and applying them all to our new G.U.T.S, ranging from the already seen HUB#1 and a big variation of tunnel types that will be used with it.

I’ve started from the entrance towards the inner pieces, which are semi modular due to the PLA system. You’ll see variants as you go through them so it's not bland or repetitive.

I tried to keep it clean so Jace, or anyone that wants to build on top of the system, can do so with ease. Creators can not only change what is in said tunnels, but can easily make their own path and storylines within by just changing a kit’s piece from dead-ends to further tunnels and room connections. Overall the direction grants us a really nice structure for expanding the tunnels, (literally) in every way.

To top it off here are some development images for you to look at. Till next month. Cheers.


We wanted to give two of the most famous dinosaurs their own spotlight piece of a 1-on-1 encounter. They were designed to mirror each-other and reflect the opposite outcome of a brutal fight where neither escapes unscathed.

Posing both animals was an interesting challenge with the Trike victory painting, because in early versions, the trike looked as if it were guarding the Tyrannosaurus body as opposed to standing on top of its attacker after finally bringing it down. Changing the arm position to be less possessive looking, sprawled out overtone the rex and adding a little more fear to the triceratops face helped bring the tone back to where it should be.

The Rex victory version of the painting had its own hurdle to work through. With the overlapping nature of the pose, lighting was going to need extra attention to make sure the outline of the Rex head didn’t disappear into the shadows.

For fellow illustrators: Plan out your lighting thoroughly in advance, you’ll save yourself a lot of headache and course corrections down the line!


This month QA has been focused almost entirely on Maiasaura, ensuring that it works with all of our existing systems. As we add more species to the game, as does the number of possible issues between them, so it was important for us this month to check it against absolutely everything. I can say with confidence now that we’ve checked it against all abilities in the game and they all work as intended. Deinosuchus can lunge and drown it, Ceratosaurus bite applies bacteria correctly, Dilophosaurus hallucinations can spawn and attack the Maiasaura, etc.

As you can see, the number of tests quickly stack up as we add new species; so, we’ve been working on streamlining this process within QA to make it much more efficient in the future.

To give you a video example of an interaction that was bugged with the Maiasaura, here’s what happened when an Omniraptor was bucked off of one:

In case it wasn’t obvious from the video, the Omniraptor would shrink dramatically in size each time they were bucked off! This wasn’t as straightforward as that though, as this issue only showed on the Omniraptor’s client, causing them to “jitter” for all other players.

As well as interactions with other species, the Maiasaura also of course came with a plethora of its own problems. Here’s how it looked if it grazed while turning:

We have also been testing the other new additions to the game. For example, Gastroliths are being introduced in the next update, allowing users to reduce their hunger faster.

I’d like to give a big thank you to all of those that have been continuing to report issues to our community bug report form (https://forms.gle/ufXDnxNfhRhZ7CCi8). Without them, we wouldn’t catch a lot of the problems that exist in the game. One report that we did come across from a report a while back was the aptly named “fish prison” issue – players that were swallowed by an elite fish would sometimes never be allowed to respawn, becoming stuck following the fish until forced to relog:

Lastly, QA has been playtesting the Maiasaura to make sure it feels fun to play as. We’re aiming for it to be a fairly tanky, swift animal that deals moderate damage in favour of better crowd control capabilities. The growth is set up in a way so that it quickly grows to its subadult stage, then slows down as it progresses towards a full adult. It is also able to quickly switch stances between being quadruped and biped, allowing it to adapt to various circumstances. My favourite ability is the “Shove”, which can be used while sprinting, allowing you to send smaller characters flying. I’m very much looking forward to getting this character into your hands very soon with a horde test, which we are aiming to push out within the next week.

This month I worked mainly on finishing the diet system. The stomach grows with the dinosaur and food no longer scales with the stomach. This doesn’t have much impact on smaller animals, but large ones that have quick moments of growth are forced to eat far more often. The combinations for diets were simplified but now they are not dependent on having active slots. The value of a nutrient increases the bonuses proportionally with them to a cap. Salt licks were adjusted to better help with vomit sickness but they also drain a nutrient while using them. Don’t forget to set your active nutrient in the Dinosaur Profile if you want to control which one it is.

The diet and nutrition changes also allowed us to include the eggs in the diet system. Now players can grab eggs from female corpses that had gestated them before dying or steal eggs from the nests. Changes will be made to this in the future to account to specific “Egg Thief” dinosaurs but for now every carnivore can benefit from stealing those nutrient rich eggs from nests

To conclude, some fun things for server owners. A lot more server configs were added to help modify gameplay experiences and admin commands were updated to be faster and more responsive. Mass Migration was also added as a config and more is coming soon with the introduction of “Nesting Patrol Zones” but otherwise the system is done.

See you next time.


I’ve been working on some features you may have already seen for yourself in the horde test. Egg gestation has been added along with some adjustments to the nesting system. This required several changes, as previously you only laid a given number of eggs depending on your diet, but now you can choose how many you want and even lay them at different times. I also added scent support for them since they can now be picked up and eaten.

I also continued my work on the maiasaura. Most abilities were actually quite simple to update to support the bipedal and quadrupedal states but out of all things grazing happened to cause the most problems. I ended up reworking the animation setup for that, but that’s something that had been planned anyway. Maiasaura now moves quite smoothly.


I have been busy working on a new navigation system for fish which can translate for use with swimmers and eventually flyers. I’ve added the fish's capability to try to chase down and eat smaller players which you may have seen in the hordetest.

With a lot of the back-end systems now completed my focus is AI. The base logic for most animals is completed with some big improvements to navigation and performance. The Pterodactylus and Compsognathus AI has been made using a new system which will allow larger hordes to spawn and interact with the world. Though these are WIP you will still see them showing up around the island. Each animal will get some improvements to their behavior now the foundation for base logic has been tested for performance and reliability.

To close, some new RCON commands have been added for server owners that you can find in provided documentation.


It’s been rigging time, getting ready for the next round of animals to get back on their feet. Kentrosaurus is the first to use our new rig system that we’ll be using from here on out.

As far as animation goes, I’ve been on Maiasaura and Allosaurus lately. Maia never really was a pushover in the old days but it’s got a new trick up its sleeve for Evrima. Best not to make mommy angry.

The Allosaurus is getting new locomotion which is just about done for the adult and I’ll be working on the juvenile locomotion in November.

This month has just been more work on the Maiasaura. Along with polishing the adult calls I’ve also designed a set for its juvenile stage, maintaining the cute burbles and pops consistent from legacy. Additionally, I’ve completed the implementation for the calls, ensuring that the pitch and volume modulation as well as the dynamic mixing of vocal call layers over growth and other variables (such as when it loses its voice) all sound appropriate at every incremental stage.

I’ve also gone through all the adult animations adding in footstep and foley sounds. Taking into account both its bipedal and quadrupedal locomotion meant double the number of places to sync.
I’ve now started working on the vocal sounds for the rest of its animations, starting with its attacks. With varying directional attack animations based on the angle of attack, a few different attack vocals of different lengths are needed, providing a coherent yet natural variability to compliment the variety in the animations.


Hey all! It’ll just be a short one for me on this devblog as QA have been working solely on bug testing both recent additions and some upcoming mechanics. Here are a few of the more interesting issues we encountered over the past month:

As you are all probably aware by now, one of our recent additions was the inclusion of our first ever seasonal content. Of course this came with some interesting bugs, such as being able to court and nest with dead dinosaurs:

Additionally, dead dinosaurs would leave behind some of their belongings if they entered spectator mode:

We’ve been testing out some new Scavenger AI that have proven to be much more performance friendly and reliably spawning on corpses, though have had a plethora of issues in their development. Thankfully, you can expect these issues to be fixed for their release:

Tenontosaurus had a fun gravity defying kick that set people up for combo damage instead of sending them away from a player:

We also found the omniraptor decided it would also be a ghost for a build and disappear whenever it would latch on to a player:

Happy Halloween! October was an interesting month. A lot going on. There’s so many irons in the fire right now. And since I’m tired, I’d prefer to do more showing than telling.

Creature side there’s Tyrannosaurus, Triceratops, Maiasaura, Allosaurus, Austroraptor and soon Kentrosaurus all being worked on in some capacity across varying departments. Their animations are either complete or nearing completion for all but kentrosaurus who is next in line, followed by baryonyx.

The animation team has been doing an excellent job and stood up to the task I placed before them, which was to get the austroraptor animations complete in record time. The animal has land based movement, aquatic movement both above and below the surface of the water, and all that feather work. I am very proud of what we managed to accomplish with such a frankly annoying creature and I’m sure the entire animation team is as relieved to be bringing it to a close as I am.

There are new AI additions coming too. Destined for a life of being fodder for hatchlings and juvenile carnivores, these small animals will be showing up in specific locations and be yet another element we’re incorporating to bring the whole island to life. Grasshoppers, rats, dragonflies, and lizards to name a few.

Elders are looking pretty good. I’ve attached some images of adults and elder comparisons, some of which are already being moved into the game for current playables.

I hope you all enjoyed the Halloween event and continue to have some fun with it. That’s all for this month. The next two months are gonna be here and gone before we know it so we haven’t a moment to spare. Catch you next time.

The Migration Zone testing went well and I'm happy to say the game works with or without the settings enabled, as well as Diets/Buffs, Patrol Zones, and Mutations. Additional configurations were added for server owners to further customize the experience they wish to give players and rebalance settings.

The User-Interface changes are rapidly coming to a close. It took a bit of time to figure out how to properly transition from an old retro style console interface to a sleek design in-game without it becoming jarring but I feel we've figured it out. I've attached a few previews of the layout approvals of the upcoming UI but the transition sequence is still too rough to display. The VFX of the menus can be toggled off and there will be a small color selection for menu color.

VisualTech48 made some fantastic progress in everyone's favorite general underground transportation system. Many of you by now have seen the proto-entrances that exist on the island and I've attached some images of their upcoming replacement. Someone somewhere is asking about the vending machines and yes, they are temporary stand-ins because you know AE has only the finest liquid provisions to provide to their workers.

Much like the Hubs, there will be a degree of variation among these that can allow various sections to branch off into other rooms, halls, or tunnels, including the elevator shaft. Coming shortly after these major connections are complete will be the destroyed tunnel variants that spill out into caverns and other internal environments.

Certain lighting is temporary as we work on the power system and as always, be nice to the tyrannosaur. They're just visiting.

Lastly, I’ll just fire off some things going into the next HordeTest with varying degrees of context.

Thermal vents and wind currents! These can affect flying creatures by providing speed boosts and lift and no stamina cost to a player and slowing them if they fly against it. These airways are also customizable and can be set to be active during a specific time of day, if they are immune to or affected by weather states, or if they’re just permanently active. You can expect all those natural thermal vents that are active during the day will go away during heavy rain or storms, as well as varying wind currents that become active at night to help move our flight-capable population around.

I know everyone is excited for the next animal and the Maiasaura will be stomping over that line for testing very soon. It will also be in one of if not the first HordeTest for the next patch.

I don’t have additional information context for these but they’ll be there:
Spawn Codes.
Gastroliths.
Nesting Zones.
Replay Updates and Effects.

Godspeed and see you on The Isle.

- Don

Hey Islanders,

This month I was busy reworking the math behind food, which also changed all diet code including the combinations. Now slots no longer need to be activated anymore, the bonuses are scaled with the amount of nutrients until a defined maximum. No more getting full before you receive any benefits from eating what is on your diet! This change also made all balance changes easier for all animals, but also for calculating food in migration/patrol zones. This also allows us to give server owners some control over the food balance in game who may want a more customized experience.

Besides that and the new slot combinations, new mechanics are coming soon such as Gastroliths. These are small rocks that will manually drain food contents from the stomach. This does not affect nutrients or anything other than the stomach value.

Lastly, I also worked on balance changes for mutations, a few have been changed completely, others merely received buffs or debuffs and a lot of bug fixes and improvements.


In the beginning of the month I worked on the update we recently released, which was mostly just bug fixes, including a funny one where herrerasaurus was able to latch onto the air and just climb up infinitely into the sky. As much as I would like to buff that dinosaur, unfortunately that one was taking it too far.

Other than that I was working on various maiasaura features as it moves closer towards completion. It has different attacks depending on its stance so it’s a bit of work to finish all of them but they’re unique enough to feel worth it and the movement system is functioning well after some bug fixes which I’m really happy about.


I’ve been working on Maiasaura’s calls to get some space and perspective from the Tyrannosaurus. I am maintaining the trilling and warbling from the original vocal signature but bringing them up to the standard expected with Evrima. This is being achieved by using similar sources for the warbles; a mixture of female human screams, pitched down fairly low which creates the oscillation in the sound and combining with the growls, snarls and trills extracted from whale vocalizations. I’m introducing sounds such as pitched down bird calls as well as sounds from animals like tapir etc. to create a bedding to underpin the warbling that gives the sound more body as well as a more musical quality.
The other breath and throat layers consist of gurgles and growls from camels to keep it consistent within the hadrosaur family (as that has been used as the base for the Tenontosaurus sounds as well), along with pelican and flamingo calls which when pitched down heavily give a thick growly animalistic texture that compliments the movement of the warbling. Looking forward to sharing more soon. Thanks!


It’s been a long month with a variety of Dinosaurs. First up was some T. rex subadult animation, getting the animations needed for testing some of it’s mechanics ready before we expand into the rest of the Rex growth stages. I’ve said it before, but Rex is a very different beast compared to legacy and each growth stage is practically a different animal, both in terms of how it plays but also in the amount of work that is going into it.

Maiasaurua requires two sets of locomotion animations and is complete. Players will be able to swap between bipedal and quadrupedal locomotion, each with their own benefit to how the animal moves.

And the Austroraptor locomotion has also been finalized. The amount of feathers on this guy made it a bit of a bear to work with but its locomotion is almost complete. Austroraptor has a pretty complicated rig, which leads me into my final project for the month: Kentrosaurus.

Due to the increasing number of features required in our animation rigs for the month, I decided to use Kentrosaurus as an experimental rig which will hopefully be more ergonomic and robust when the animation team is working with it. The rig is nearly done and shows a lot of promise. I’ve also taken the extra time to build a custom rigging toolset which should make rigging any future animals much easier and faster. With Kentrosaurus, what usually took over a week to do only took a day to complete. Work smarter, not harder.


We’re up to a lot currently. We’ve got some changes to diets, changes to migrations, the addition of patrols, elders being integrated, changes to current playables and production still churning on new creatures. There’s never a dull moment.

Work done to migrations, diets and patrols should give you guys more flexibility for how you want to grow your animal and the choices you make during their lifecycle. Moving animals around in more ways so you can potentially have an interesting experience no matter where you happen to be on the island.

We’ve also got some changes in the works for nesting and friend invites. This is aimed towards allowing you easier ways to play with your friends without sacrificing the integrity of the island’s ecosystem or creating abusive gameplay systems. We want to further incentivize nesting on the island in ways beneficial to both parent and offspring and in doing so, help make play with your friends more streamlined and accessible.

Patrols are going to slowly but surely start being expanded to include more ingrained experiences that are varied and make sense for the island and for your groups. No details to share just yet as we want to work out the systems mindfully before unveiling them. But the goal is to give you more experiences that will help the island feel more alive and dynamic. Which is a key component across the board. Which is to make the island itself feel like a living breathing ecosystem. Full of all manner of flora and fauna that you can interact with and in some circumstances, interact with you.

Sticking to that design goal helps ensure that no matter where you are or what time of day it is, a realistic experience can be had. Which will be made all the more apparent when humans enter the game permanently. As each and every excursion beyond the relative safety of a secured facility is truly and genuinely a walk out into the unknown wilds where the creatures of The Isle live out their lives with or without the existence or knowledge of the humans on the island.

Elders are also getting some legitimate work on them which is very exciting as the system will round out the gameplay loop for our animals which has been a long time coming. All creatures will age on the island but the elder is where strength meets experience. For those that have maintained a quality existence throughout their lives, the reward will come in the form of an elder: a peak representation of the species. This is a stronger and more capable age state than a healthy adult. For those creatures ineligible or incapable of reaching elder status, a slow decline into a frail elder stage is all that awaits but the choice is yours.

I’m looking forward to doing more rex testing this week to get its features where they need to be so it's safe to knock out its feature mechanic animations for its lifestages. We have to get the mechanic working the way we want first before completing the lifestage animations for those features. That way, we don’t have to redo work should the features need to be adjusted for some reason. Thankfully, with a click of a button and an export, those lifestage animations are done. Praise be! The tyrannosaurus is definitely shaping up to be one of, if not the most production intensive creature we’ve ever made, primarily due to how much it changes over the course of its life. As we’ve been vocal about before and I feel bears repeating now, we are committed to the tyrannosaurs feeling appropriately like a tyrannosaurus: starting off life extremely vulnerable, slowly scaling into one of the most powerful predators to have ever existed. A healthy adult tyrannosaurus in The Isle is going to be a force to be reckoned with and grow into true apex predator.

The maiasaura has also been rounding the corner towards completion. Getting its sounds created and integrated currently. It should also be ready this week for some testing as well to ensure it's on the right track. Which ultimately shouldn’t be too challenging considering its mechanics are fairly simplistic. I’m excited for its inclusion to the roster cause no manner of dinosaur media is complete without a hadrosaur in my opinion. Its playstyle should remain similar to what it was in legacy for those that remember that. It should be strong enough to defend itself from smaller predators but should definitely consider fleeing as an option from larger more dangerous threats. Which is primarily the winning survival strategy for most creatures. Its ability to change stances should hopefully provide more flexibility for its survival. It will be interesting to see how they are utilized in your hands.


At the end of this devblog I’ll include some skins that have been in the works the past few months that were posted on the community discord and some other pieces of development content. Treat each other with respect. See you next time.


Hello Islanders,

When Migration Zones were originally tested, they were left active and always on to ensure that the mechanic was working. This led players from one migration to the next with there being no applicable downtime in-between, resulting in a “Keep moving or starve” gameplay experience unless you could supplement your diet with grazing along the way. To be clear, this was not the intended purpose of the Migration Zones initially. We left these active and constantly cycling to ensure it worked properly and consistently. Migration Zones have been toned down and do not automatically adjust player diets to everything in the location they are summoned, but strongly increase nutrient yields from preferred foods. These also take time to activate, ensuring that a migration is a less frequent occurrence but guarantees a larger overlap of players.

Patrol Zones are limited to an individual or the group that they lead (group members always have the patrol zone of a group leader), which are smaller pockets of exploration areas across the island that can yield food and benefits should a player go there. For carnivores, patrol zones that have or had recent player activity in them that are also part of your diet will activate after a short delay. It won’t guarantee that you go to a zone and just see players running around, but it will give you a staging point for a hunt.

One of the biggest tests on the immediate horizon is going to be disabling Migrations and Patrol Zones entirely. Though these features are important to the survival aspect of the game, do not forget that sandbox is king. These features may not be relevant to other experiences, official or otherwise, within The Isle.
Nesting gameplay is getting the attention it sorely needs. Various nesting areas are being drummed up around the island, some of which are a common design where any animal can reach and nest, but a few bespoke locations may be harder to reach or inaccessible to some animals. These locations will have unique patrol zones designed to help parents raise their young and remain nearby without forcing the parents to struggle too hard for resources. (Final Note: There’s also some testing going on to allow eligible but unbonded animals to use their courtship calls at a longer range, not unlike a mating call, to find other players who want to create a nest and I’m hoping it works out as a finalized addition).

UI update? UI update. “Minimalist AE console interface” is the direction I started in and Seiza has been hard at work with me going over the various screens in the game as we move towards a unified look and feel. I’m happy to say it mimics the style of what is seen in our YouTube videos and I feel that we’re close to the end of any edits and updates to screen navigation. Once this is complete, we will begin filling in the intentional empty spaces with various lore information. Ultimately, it’s a lot less cluttered and more direct on player input. (I know what you’re thinking. Where are the screenshots? Expect new UI media to randomly start finding its way into the Discord and Phase Three in October.)

Just a quick update on the random spawning for official servers: Randomizing the spawn region for players has helped considerably with displacing problematic player hotspots on the map but brought the obvious problem that it made it infinitely harder to find and play with friends. Spawn Codes are being worked on to allow players to join one another as they start the life of their animal. No further information at this time until it goes through testing to fix abuse cases, but I’m confident that this will resolve being able to find and play with friends when starting a new life.

Mutations and their changes have been seen in some older streams. Of course there have been adjustments due to problematic behaviors but some mutations have received more bespoke adjustments to make these choices matter to a player more with more obvious consequences or changes in default gameplay. Something like “Cannibalistic” will require more consideration, as selecting that mutation may alter your coloration to show everyone just exactly what type of player you are. Other mutations that alter percentage values of your animal will be drastically reduced in effectiveness, making way for the Elder system that will allow those mutations to stack in effectiveness (up to point) if you complete a full lifecycle as the animal.

Lastly, this year we will host a limited time seasonal event on the HordeTesting servers. This was a pitch done over an extremely small amount of time that wasn’t meant to interrupt general development, so it is in no way visually perfect but it’s been very fun in closed testing and I hope that you all will enjoy it when the time comes. Just remember, there is no cure.

Godspeed and see you on The Isle.

- Don

This month I have been mostly focused on the new features for pounce and finishing up some systems before moving on to the new playables. As for pounce, the new slot swap system is finished which allows players to manually swap slots when latched to a target by spending some stamina. It can be used to better coordinate with other pouncers or simply be used to avoid being knocked down when the target uses nearby trees or objects.

Along with that, pounce now has some incoming manual control to attack while latching. Latching on to players only causes a small amount of consistent damage, but allows players to tap/hold the primary attack button to do extra raw damage, or also tap/hold the secondary attack button to deal no raw damage, but high bleeding damage. Both actions spend stamina, but allows for more dynamic combat giving players more control over what type of damage they’re dealing to pounced victims. With this bucking has become significantly more important for the victim and it has received some major attention to prevent it being an unfun war of attrition.

Lastly, some additional adjustments were made to the patrol zones that should help encourage players to explore the map and should be featured in the upcoming hordetest.


Most of my work this month was done on the maiasaura. The dinosaur will have the ability to switch between bipedal and quadrupedal stances, which affects its movement in different ways. The most time consuming part however was setting up all the different interactions to support both stances. I also had to reorganize some existing data, but on the plus side this also opens up the door to new mechanics such as sprinting while crouching. The maiasaura will also have different attacks depending on its stance which I will be working on next.

Other than that it’s mostly been the usual bug fixes, but there were some quite significant balance changes as well. For one, the carnotaurus has been made slightly smaller which has an effect on its weight which should feel more appropriately located within the roster while its speed is still being evaluated. I also updated the ceratosaurus’s bacterial bite, which now takes into account the relative size of the two dinosaurs and also how much bacteria you have available. This has made it extremely effective against small target animals near its weight class, which has led to some interesting new space for the ceratosaurus.


Focus for me this month has been moving some of our smaller scavengers to a more robust and visually appealing system that allows more complex interactions. There are some new interactions coming to the world that involve this system, including some sound traps that will give away careless players.

Psittacosaurus has received a few behavioral changes and bug fixing based on QA testing with the hope to include it in the upcoming hordetest. They have a few burrowing locations throughout a few biomes, but can also be found in some sanctuaries.

Lastly, I’ve made a new RCON tool for internal use and hope to get that into public hands once it’s been evaluated and tested.


This month I’ve been working more on refining the tyrannosaurus sounds. A lot of the sound palette of the calls has been changed, namely a lot of the source sounds being used for the core elements; instead of relying almost solely on animal sounds I started working with recording and processing new source from non-literal sounds – recording metal screeches and groans, glass squeals and moans etc. This took a fair bit of experimenting to find the right source, which once found is then blended with the animal elements to help these sources sound more organic as well as additional processing to give them a vocal quality such as modulated resonant filtering and tremolo.

Specifically for each call these are the main changes that have been made:

• Injected more dynamics and movement into the broadcast so it has more inconsistencies and is not just a flat note as well as improved the mix of the different layers.
  
• Mix improvements and more variations of the alternate broadcast
  
• Adding a distinct core to the generic call over the chunky gurgles and groans that it solely consisted of previously
  
• Reworked the danger call - reducing the amount of noise that was cluttering the mix from breath and roar layers as well as creating a more unique core to the sound which will be easily identifiable.
  
• Worked on blending the layers of the attract call better.

Additionally some of its attacks and idles have also had edits made, making them tighter and removing undesirable elements and more adjustments have been made to the attenuations; refining how they travel and checking at various distance ranges to make sure it sounds appropriate. A custom attenuation setup has been added for the broadcast which has a separate power layer to help give a terrifying impact and crunch even at distance without other breathy and growly elements being audible at distance.

Other tasks I have also worked on this month:

• Worked on an ambient cue for troodon’s venom that will spawn randomized vocal sounds during its new envenomation setup, same as for the dilophosaurus’ which has now also been implemented.
  
• Improved the timings of herrerasaurus’ pounce attack vocal and foley sounds
  
• Fixed gallimimus’ mobilize call, dryosaurus’ dodge vocal and deinosuchus’ lunge vocal (in water) not playing
  
• Started some early concepting on updating maiasaura’s calls to be in line with the sonic aesthetics.

This month I got to work on some edits for the elder diabloceratops, beipiaosaurus and the juvenile/hatchling concepts for austroraptor. The direction for the little austros was to go in the opposite direction of the long and sleek adults (Design wise) and make the younger versions progressively rounder and fluffier the closer to hatchling you get. Needless to say baby birds were a big inspiration, mainly that of fowls as well as some songbirds.

On the flip end of cute fluffy dinos, I’ve been doing some additional work for the Gen1 customization, including some close ups and extra detailing of the alternate head variations to get the monstrous humanoid ready for the horror side of the isle.

Another busy month of animation. Been hard at work on a number of dinosaurs. Triceratops sparring is really coming along, I recently completed the horn locking and it really is impressive how solidly two triceratops lock together when sparring as opposed to how freely a diabloceratops could move.

Also been working on getting austroraptor finalized and ready for animation. Its rig has a lot of moving parts but it’s all come together and a few people on the animation team are already working with it to get its list of animations done. A few of the other animals we’ve been working on, like triceratops, maiasaura or diabloceratops have been in legacy and had some animations we could reuse, but austroraptor is different in that it has a whole new skeleton and everything has to be remade from scratch.

Lastly, tyrannosaurus has been featured heavily in my current workload while getting its more advanced locomotion animations completed as we continue to polish the sparring and life stages.

QA has been spending a good amount of time on balance testing over the past month. Below are just some of the many areas we’ve been looking at:

One of our main focuses was testing the new pounce changes. Being able to switch between pounce “slots” while holding onto your target has been proving extremely useful in combat, allowing the user to avoid having to leap off of a cliff because your target positioned themselves on the edge of one. Having the ability to also pick between raw damage or more bleed with the different mouse buttons has also expanded the utility of the attack. Need to bring something around your size down faster? Focus on the raw damage attack. Target too big to bring down quickly? Focus on using the bleed attack to keep the pressure up with your pack.

Ceratosaurus now takes into account its own and its target’s weights when applying bacteria through its bite. This change alone has shaken up its combat prowess, allowing it to more quickly cause smaller species to vomit while larger ones take additional bites. This change will be even more obvious when we get our apexes in, as the ceratosaurus won’t be able to make them vomit in a few bites, solidifying its place in the ecosystem. Ultimately it is still one of the smaller carnivores on the roster.

Tacking onto Will's highlight of the new environmental and attack sounds for dilophosaurus and troodon, their envenomation mechanic has also received their suite of sounds, including ambient vocals from hallucinations. This gives the effect a whole new intensity as the player now feels like they’re constantly surrounded, even when they’re not. This has been very enjoyable to witness in playtesting, as people are now much more paranoid than before.

Night vision has been very well received by the QA team and is undoubtedly the best iteration we’ve had so far. I believe this new system will finally put an end to the case of people playing with NV on constantly, as having it enabled during the day doesn’t give the player any advantage while still giving them a massive advantage at night. As well as this, I’ve tested it against gamma to see the difference, and the results have been very promising—I believe players won’t even feel the need to increase their gamma anymore because of how well it works. QA has been running combat tests at night, and the new system makes the difference between a nocturnal and diurnal creature that much more apparent while still giving all playables an enjoyable playing experience.

For the past few months, QA has also been hard at work cracking down on bug finding, which has led to the discovery of some very strange issues:

Pteranodon AI have decided that the most efficient way to take off is by burrowing their way through a tree first:

The animal AI seem to have grown tired of being endlessly hunted and are rising up against dinosaur players. Be on the lookout for each other:

Beware! The infamous land croc returns with its new dodge ability:

Last but not least, here’s one for the maiasaura:

Yet another month that has zipped on by. There’s so much going on right now I don’t know where to begin. Since I’ve got a maiasaura trying to kick me in the face at the moment, I’ll drop some content instead of writing a lengthy post.

The animation team has been hard at work cranking out these animals that you should start seeing more of in the not so distant future. There’s a lot of change incoming. Changes to pretty much every species in the game. Changes to the environment, changes to nightvision, changes to abilities etc. There’s also going to be some animation blending changes that may not make it into the next Hordetest but will likely make an appearance shortly thereafter.

Here’s a sampling of some of the skin work that’s been done for the animals including the tertiary skin for tenontosaurus. The other tertiary skins have been created and should be making their way to you.

Additionally here’s some animations for the austroraptor as the animation team starts knocking it out. You can expect it to be every bit as energetic as some of you may remember it being from legacy but in a fully realized fashion. This is an omniraptor in sport mode, but be careful since it’s also more delicate.

Rounding out, here are some animations for trike and rex

There’s still so much work left to do but we’re getting ever closer to our goal. We set out to improve upon the concepts present in the legacy version of the game and those planted seeds are bearing fruit. More work is being done on the humans as well to get them to a place that will allow them to fully function in the game concretely. As always, be good to one another and see you next month!
