10/15/24 edit: new discoveries and oddities list added!

Starting from weakest to strongest, here's a list of zombie and animal enemy types I've encountered in the Urals, plus some oddities I thought were worth mentioning.

TURNED

Lesser Zombies: Often times unclothed, they can be found at most civilian locations and are rather weak, and drop the lowest xp (being 1 xp on the multiplier I use). Zombies in togas at the Shad Tchup Ruins also fall into this category. Some medic zombies at various military triage areas and hospitals are in this category as well.

Standard Zombies: Run-of-the-mill Turned, found at basically every location. Some have mutated visually with grotesque growths. They drop slightly more xp (2 xp) than lesser zombies and normal civilian loot based on their profession.

Bandit Zombies: These zombies can be found somewhat rarely in locations where mischief is prevalent. They are just barely stronger than normal zombies and drop a tiny bit more xp (3 xp) than usual. They can often be seen with red or cobweb bandanas.

Explorer Zombies: Often found in groups of 1-3, these Turned occupy civilian, rural, and industrial locations and can be identified by their explorer outfit. They have seemingly standard health and damage compared to normal zombies. They drop a little more xp (~5 xp) and can sometimes drop ammo boxes.

Coastguard Zombies: These Turned are common in shoreline areas and can be found at multiple stations across the map. They have slightly more health than normal zombies, but unlike those in Hawaii they are not equipped with any military hardware. They drop coastguard clothes and some xp (~4 xp).

Military Zombies: Found at every military location in varying numbers based on how good the loot is, these Turned are marginally stronger in comparison and commonly spawn with vests and helmets that increase their resistance. Their drops are more valuable (7 xp) with military clothes, armor, ammo, magazines, and even guns like the Zubeknakov, Yuri, and Teklovka. They often cause bleeding with how hard they hit. There are multiple factions of military zombies including Russian, Greek, and Canadian/American.

Fallen Reds' Zombies: Somewhat rare to find on their own, these Turned spawn in groups in certain areas where Red Maxim's soldiers have failed and become infected, such as Vizhay Station and the Private Estate south of Bayanovka. Their spec ops armor makes them very resilient to damage. They drop slightly more xp (8 xp) than military zombies as well as ammo and guns, rarely. They seem to deal slightly more damage than military zombies as well and have a little more health.

Biohazard Zombies: These Turned can be found rarely accompanying military zombies and near certain deadzones. They are worth killing as they drop biohazard gear and medicine like standard Scorpion-7 zombies in Vanilla Unturned, as well as a good amount of xp (10 xp).

Mummies: Often found in ancient or religious places like Irbit Cathedral and the Monastery, these reanimated corpses are somewhat tankier than normal zombies and drop decent xp (~14 xp). They don't seem to have any special item drops, however.

Advanced Medical Zombie: Fairly uncommon variants of normal medics, these Turned spawn in the same conditions as normal medic zombies. They are identified from their Civilian Nightvision and have around as much health as military zombies, dropping decent xp (15 xp) and medical equipment.

White Cultist Zombies: Seemingly the opposite of Red Maxim's soldiers, these Turned also wear civilian nightvision alongside white + gold robes. They are much rarer and seem to only spawn in groups of 1 at random obscure locations, dropping decent xp (~16 xp).

Ghillies/Bushwookie Zombies: Found rarely in a number of locations, including civilian and military, these Turned are slightly tougher than Biohazard Zombies and hit rather hard. They are most commonly found in groups of 1, rarely are there multiple at a time. They can sometimes be seen with Military Nightvision. They drop good xp (20 xp) as well as ghillie clothing and netting.

Izlöm: The first non-standard Turned, these tan-skinned zombies with wretched faces can almost always be found in groups of 1 at set locations, including aircraft crash sites, places of worship, and areas with high military activity. They have substantially increased health, dealing around the same damage as military zombies. They drop loads of xp (~75 xp) and can drop weapon attachments. They are based off of the cut enemy from S.T.A.L.K.E.R. of the same name, meaning "fracture" or "fissure" in Russian.

Bloodsuckers/Krosovos: The second non-standard Turned, these mutated zombies can rarely be found in similar conditions to Izlöms, but more attributed in underground and rural areas as opposed to military settlements. Headshots are practically useless and the only way to kill them is by hitting their arms and legs (legs being most effective). They deal immense damage, cause bleeding, and have a massive amount of health. They drop a lot of xp (~120 xp) and can drop leather. If you see a crawler or sprinter bloodsucker, you might as well just run away. They are based off of the Bloodsuckers from S.T.A.L.K.E.R.

Ancient Explorer Zombie: By far the rarest of the standard zombies, I've only been able to find one of them on the whole map near the lightning-struck tree at the Frozen Lake in the Southeast corner. He can be identified by his aged cloth outfit and wood snowshoes on his back. He has insane hp (almost that of a mega) and drops a huge amount of xp (~250 xp if I remember correctly).

MEGAS

The Vampire Hunter: This special mega zombie can only be found in final room of the Ghost Barns, surrounded by military zombies. Perhaps he is the ghost referred to in the name? He drops a load of xp (~650 xp) as well as police loot. [uses the Vampire Hunter stockpile outfit]

Yeti: Mythological cryptids spawn in specific locations on the map, including the Frozen Lake in the southeast corner, in Gorod Morgan, and down a small slope at a certain legendary pass by the skeletonized corpses of unfortunate hikers. They have INSANE health (seriously took at least 5 minutes of stabbing in the back of the head with a butterfly knife to kill, thank god for stunlock), deal high damage (like getting hit by a boulder thrown by a normal mega) drop a ton of xp (~1150 xp) as well as leather and venison.

Davy Jones: Another of the rarest Megas, this guy spawns in the heart of the Shaytanka Bog (I've not found him anywhere else) and can be hard to spot with his green body and cthulhu head. He also deals immense damage and has incredibly high health, slightly less than that of the Yetis. He drops a ton of xp (~850 xp) as well as Loonies and Toonies. (yay!)

The Bolkov Beast: This massive knight zombie clad in black and red armor resides somewhere in the Bolkov Castle. Be ready to pour hundreds of bullets into this guy to get his massive bounty of xp (~1600 xp) as well as his drops of high tier ranger loot! [uses the Lu Bu stockpile outfit]

Super Bushwookies: A rather rare high-tier variant of the ghillie zombies, I've only found these megas in two specific locations. One can be found on the first floor of the Severouralsk Hotel and the other in the quarantine chamber of the Urals Research Center. They will drop extremely valuable military loot.

Various other Megas can spawn rather commonly in most high-traffic areas, varying from construction Megas to military Megas and even some police Megas. Instead of dropping standard mega loot, they will often drop loot based on their profession. (police mega drops Kryzkareks and Vonyas alongside police clothes and handcuffs; construction mega drops generators and spotlights and metal materials, etc)

ANIMALS / CREATURES

Spiders: The first animals on this list, these eight legged freaks come in multiple variants of size and colorings of black or brown. They are dreadfully hostile (as with all animals on this list) and guaranteed to freak you out if you encounter one. Their health and damage are relative to their size and drop 2-8 spider eyes, which can be eaten, used to craft the creeps and crawlers poster, or traded with Stanislav for 16 XP each.

Chimeras: Arguably more terrifying than the spiders, these gray creatures are often hard to spot among the terrain. They will charge at you much faster than the spiders and deal more damage, having higher health as well (~8 pistol shots). They seem to be slightly unfinished as they dont have any ragdoll upon death. Beware using melee or approaching the area where they died as a glitch occurs where it will start to deal rapid damage in that area, even after it is dead. They drop nothing but good xp (~40 xp). I believe they're based off of the Chimeras from S.T.A.L.K.E.R.

Icky Bugs: These weird, green carapaced bugs are also difficult to spot in the terrain. Much like the chimera, they're unfinished and have no drops or ragdoll model. The same glitch occurs as the chimera as well, where if you approach the area where it died you will take rapid damage even after it is killed. They thankfully move much slower than the chimera but are much tankier, taking around 10 pistol shots.

Demon Spider / Spider Queen: If you thought the Yeti or Davy Jones had a lot of health, you probably don't want to try fighting this terrifying, beastly spider. I've only been able to find this horror in the secret chamber under the Ancient Wall. It took around 80 shots from the CB-98 (which does around 900 animal damage) and two full Hell's Fury drums (cheater) to finally kill it, which got me ~2000 XP as well as a bunch of spider eyes. This one may be a new addition as I don't recall being scared out of my skin by it when I first explored the chamber.

Anomalies: Unstable electromagnetic forces. Do not approach. They are often seen "wandering" mountain tops and rarely can intrude into civilian areas. The Isle of the Dead is particularly rife with these beings.

The Shadow: A previously sealed mine on the south bluff of the Kolonga Lighthouse is now open. Delving down into the heart of the mine is almost guaranteed to be a fatal mistake. A mortifying shadow creature dwells down here, protecting huge stockpiles of high-tier military and construction loot. The Shadow retreats into the ground when it sees the player but is too far away to hit them, preventing you from killing it cheaply. (It can still get stuck on the minecart tracks, which is how I was able to kill it safely.) It doesn't seem to have too much health, ~15 shots from the CB-98 were able to kill it, dropping ~500 XP. A miner mega zombie can also be found in the lower cavity alongside or without The Shadow, as their spawn chances are random. The Shadow seems to be the same type of mob that was used in that one Scorpion-7 adventure map as the final boss in that map's weird hidden portal room. (If you do decide to go into the mine, make sure to bring ladders so you can get out!)

ODDITIES

The Goddess: Various religious artifacts and shrines can be found that are dedicated to an ancient deity of the Urals. Busts of her can be found around the map, including but not limited to the top of Irbit Cathedral and the chamber under the Ancient Wall.

Weeper Guy: Hidden away in the Bolkov Castle dungeon, this static prop NPC (cannot be interacted with) cries among the zombified corpses of his prisoner colleagues. If I remember correctly he is also an asset used in the Scorpion-7 adventure map, alongside the...

Webbed Guy: This static prop NPC is stuck in cobwebs inside the large spider cave just north of Neyvansk Quarry. He cries for help constantly but cannot be interacted with, as he's just a static prop.

Denezkhin Kamen Reserve Mining Fissure: Just northeast of the lighthouse is a large mining operation which seems to have discovered something that should have remained untouched. A crack emanating otherworldly energy sits at the bottom of the mining reservoir.

Blood Cave: On the part of land directly north of Vizhay lies a mysterious cave whose exterior is smeared with a massive amount of blood. It seems Chimeras and Icky Bugs have a higher chance of spawning here, but that may just be a sort of placebo effect and they just end up spawning there regardless due to the spawning system for animals. There is no loot of mention here.

The Serpent Queen: Unarguably the most challenging NPC to visit (and with no reward to mention), this slimy snake empress is found in the deepest depths of the Ancient Frozen Lake. There was a challenge hosted previously by the map creator in which it was a race to find her. Not only do you need to go through hordes of Krosovos and mummy zombies, but you also need to bring explosives to break a wall leading to her chamber. I hope she will have more of a use in future updates!

Underwater Ruins: Directly south of Neyvansk Quarry is Reka Bobrovka, a large frozen lake which can be swam under. Using the break in the ice in the south river runoff of the lake will let you explore the underwater ruins, which sadly don't have any purpose other than being interesting as there is no loot or creatures. Maybe it will be a quest location in the future for retrieving something. Be sure to bring a diving tank and a snorkel!

Yamantau: Unofficially named as such by me, this sprawling military complex can be located in the furthest northeast corner of the map. It seems mostly unfinshed with no zombie or loot spawns, but I'm sure it will be utilized in future updates. I've called it Yamantau in reference to the Call of Duty: Black Ops campaign mission "WMD," which depicted Yamantau as housing a large Soviet military complex. ((If I had any input, I'd definitely make crossbows and explosive arrows have a chance to spawn here in further reference to the game as those were also used in the mission!))

Roadkill Cryptid: Possibly a reference to real life cryptid culture, another source of media, or just a cool little detail, there is what seems to be a crow-like creature's head in the road by a car in the three-way intersection between 3-Y Severnyy and the Eastern Blockade. It holds in its beak what appears to me to be a.. pokeball? I'm not sure about that one!

Train Tunnel Cave: In the train tunnel running between 3-Y Severnyy and Severouralsk is a cave which has a sealed door which requires a generator to open. Inside is a large, empty, open cave system which can be used as a good base location.

Shaytanka Hidden Bunker: In the waterfall over the Shaytanka Bog, there is a discolored part of rock which can be blown up to reveal a cave system which leads to a bunker, which is currently unfinished but will be a cool hidden location in the future!

Rod's Body: At the top of one of the supports for the Suspension Bridge is a little display of environmental storytelling. If you go hunting in the waters below the bridge, you can find Rod, or at least what's left of him.

Unearthed Safe: In the south reaches of the Bleak Tundra lies an impromptu digging operation. A safe full of rubles can be found surrounded by zombified Red's soldiers. Better bring some heavy firepower or at least something to distract them if you want that treasure.

Unmarked Research Center: Just south of the Kholat mountain sits a large Deadzone node with high-tier loot. There is a chamber under the frozen lake which houses the largest archaeological site on the map. The key from the Urals Research Center's basement is required to open the door to the dig site. There are tons of zombies, Krosovos, and good items here, as well as another otherwordly fissure in the ground. The trading NPC Kiril can also be found here, who sells the best equipment in the map and also has a lengthy backstory. You'll know Kiril is near if you see his red sickle motif.

CONCLUSION

These are just all of the enemies I've encountered in my playthrough so far and I will definitely update this with any new finds and information I come across.
