This is an in depth guide for Morbus. This guide is of considerable length, so it is recommended to bookmark or favorite the guide and read as much of the guide as you can digest, then come back later.

A professional’s guide to Morbus and Morbus: Reborn
Morbus is a gamemode on Garry’s Mod that involves two factions: the Humans, whose objective is to survive the round by any logical means or to hunt and kill all Brood aliens, and the Aliens, whose sole objective is to kill and convert all humans before time runs out. There are two kinds of aliens; Brood Aliens, which have access to diverse upgrades and the stealthy ability to transform into a human, and Swarm Aliens, who are expendable and capable of throwing spit balls. Imagine Trouble in Terrorist Town, but in space.

Morbus: Reborn is the exact same gamemode, but with many new additions, changes, and reworks of existing Morbus gameplay.

It is recommended to have played the gamemode a bit before reading this guide. The quick start guide includes a basic how to play Morbus: Reborn if you are just getting into Morbus: Reborn.
This guide is meant for every type of player, from the casual newbie to the competitive veteren. Morbus is a pretty fun, horrific experience, and it gets more fun once you are acquainted with the gameplay. There is a lot of room for scaring your friends or for outplaying someone skilled at the game.

Morbus is one of the most immersive, enjoyable game modes available on Garry’s Mod.
Morbus has many important mechanics. It’s ok if you don’t get them the first couple of times you play!

Before a game starts, there is a warm-up period for everyone to collect weapons and equipment needed for survival. The average warm-up length is 30 seconds, however, some servers may have a longer warm up period.

Humans have to survive for 10 minutes, during which they’re brought to trust others, complete needs, fend off alien attacks, and hunt down Brood Aliens.

Humans have to deal with a weight system. The more weight carried, the lower the speed of movement. The Human’s base movement speed is 275. If you pick up a M418 and a Vector, your new speed is 275 - (23+18) = 234. Minimum movement speed is 50, so even if you carry a 300 kg weapon you would move at 50 units per second.

Needs are basic tasks needed to be done to avoid losing health. They occur every 30 to 120 seconds and the time allotted to do them can range from 110 to 180 seconds. The typical human is going to do 2-5 needs missions over the course of a ten-minute round. A need takes 8 seconds to do, and during that time the human is vulnerable to anyone and anything. This ranges from a Brood attacking you or an ally protecting you, or having a nade dropped near your feet. Keep in mind, if you have an ally at low health, you might want to heal them before doing the need.

Needs will also replenish a percentage of your hp when done. So if damage has been taken, instead of using that medkit in your inventory, save it for later and do your need instead.

The damage of guns can be affected by how far or close the target you are shooting is.

As a human, if you get hit in the back by Brood or Swarm claws, you will take approximately 1.75 times the damage you would, if you were hit in the face.

Broods, when in human form, have a max of 100HP. This means using medkits is much better in human form, and taking damage is worse in human form. On top of having less max HP, damage done to a brood that is in human form is multiplied by 1.2.

Swarms have a finite amount of lives, and gains 3 for every infection a Brood or Swarm gets, or 3 every 90 seconds. If the human is killed through the usage of weapons, no additional Swarm lives are given. When there is 1 minute and 50 seconds left in the game, Swarms will continuously spawn until the end of the round. This gives a chance for the Alien side to group up and break into a fortified human location.

When a human is infected they are dead for 4 seconds. During the 4 seconds it is possible to upgrade your abilities (press c). The newly infected human will respawn in human form and next to their body unless there was an obstruction on you body (E.g a Brood stood next to the body in the location where the new Brood was supposed to respawn, the human was killed in a vent, etc.). If there was an obstruction, the newly infected Brood will respawn in the Swarm spawning location. If the Brood that infected the human is the only Brood left, and the Brood dies before the four seconds are up, the round is over and is won for the humans.

It is possible to influence the position you spawn in, as you can move after being infected and respawning.

Broods are capable of upgrading by pressing c and clicking icons on the upgrade menu. There are three trees of upgrades: offense, defense, and utility. There are also 2 tiers of upgrades in each tree. Tier 2 upgrades can be additional abilities that add more killing power to a Brood, survivability, or more utility. As a quick tip, the only useful utility upgrade is the jump, and your points are better utilized in defense, especially the damage resistances. If you want to get a tier 2 ability, you need to spend three points in that respective tree’s upgrades, then spend the 4th point on the tier 2 upgrade you want. You can also bind specific abilities to a button, as will be discussed later on in this guide.

Swarms claws do 8 damage, while their secondary attack, a spit that acts as a projectile thrown in an arc, deals 7 damage in an AOE. Swarms are also able to spit through doors, floors, walls, most obstructions, as long as they are hugging the obstruction.

Human base movement speed is 275, Swarm base movement speed is 255, and Brood form movement speed is 330. The Brood is also capable of sprinting (hold onto shift) for unlimited amounts at 390. This is upgradable by 18 in the Brood alien tech tree. Swarms can get the Haste+Leap ability in order to run faster (355) at the loss of their Spit, and the gain of a right click leap.

And finally the oddest mechanic, the damage values presented in the guide and in the game files are not necessarily true. Oddly enough, the game adds damage to all weapons. For example, the Brood claws are supposed to do 13 points of damage but really do 16. For the purposes of simplicity, if I include damage values, they will be taken from the game files it self, unless otherwise specified or if I am talking about Brood upgrades.
Across many games there will be higher skilled players who believe there is one skill, that when mastered or executed correctly, will make you better than a large majority of players. In Counter Strike this is Aim, which many Pros believe can get you to LEM (top 2%), Starcraft 2 Macro (especially at the lower levels, making an army at all times and keeping your resources and minerals near 0 at all times), to Masters (top 2%), and in Dota 2, Farming Efficiency will get you to 4k-5k MMR (top 1%). In Morbus the skill to master would be playing a Brood IN Brood FORM. This alone will make you, at the time of this writing, in the top 100 of Morbus players to ever play this game. Congratulations!

Morbus is heavily tilted towards the alien side. If you even partially know what to do as a Brood, you should win a majority of rounds. What gives the aliens an upper hand is that, provided there is constantly one living Brood alien, they turn into Swarm aliens upon death and can respawn for as many lives as are in stock.

The current upgrade build that is the most viable is the Defensive build, as shown here: 2 points into DefCara, 1 point into Enforced Scales, 1 point into Enforced Skeleton, 1 point into Endurance, then put the rest of your points into Endurance, after that get either 3 points in Sharp claws, or finish maxing out DefCara. If you get 3 in Claws, get a point in Enhanced smell, as it's very useful late game.This build is the END ALL of Morbus builds, and allows Broods to be played at a high level and to their limits. 1 point in defense carapace will give you 6% damage resistance to all weapon types, a point in enforced scales will give you 30 % resistance to SMGs and pistols, enforced skeleton will give you 25% damage resistance against rifles(This include Tesla and other Laser Rifle based weapons)and shotguns. Endurance gives you +40 hp. All these DMG resistances + HP will do a lot of work for you. Even against a great player, the shotgun, Morbus’s most notorious weapon, becomes countered. It goes from a 1 shot kill to a 3-4 shots in order to get a Brood close to death. Even if you aren't mechanically good at this game (which you don't need to be), you will live long enough to kill a human in a 1v1 situation.

Any other build is either not viable depending on a variety of factors or need a special scenario for them to be viable (such as the Adrenal Glands + Claws build, which require the lights to be turned off).

When you have gotten a kill, spend another point in Endurance, but keep this odd interaction in mind; if you upgrade Endurance in Brood form, while damaged, sometimes even when at full hp, it will add + 40 health to your max health, but not to your current health. If the upgrade is gotten in HUMAN form as a Brood, it will add +40 health to your max AND current health. Logically, if you upgrade Endurance, upgrade in Human form.

If you are a newbie and are doubtful of being able to 1v1, instead of spending your fifth point in Endurance get Screech in the offense tree instead. This ability activates whenever the Brood transforms, and depending on proximity, can blind or blur the vision of the human player. This is a nice crutch to use for a starting player, but it is a crutch. After some time you will learn how to be a good and effective Brood and be confident in taking a 1v1 that the need for this ability will disappear.

Learning how to be a Brood is learning that deception is NOT the best way to win games or rack up the most amount of infections. Playing in human form is useful in a few cases (when going to showers in mor_spaceship_v10, when you are going to use a frag grenade, a medkit, going past a room with many humans defending it, getting a grenade or medkit, putting a point in Endurance). Playing in Brood form and acquainting yourself with the current strategy of playing in the Brood form will make you a better player. Learning how to draw and waste enemy fire, just how mobile the Brood is, how to strafe and aim for hits on the back, when to be patient etc. These topics will be talked about in this guide and in future ones, but it is very important to practice them yourself. This means, as a Brood, if you and 5 other Broods are in a room with 2 humans, all of you turning WILL kill them. If a Brood is taking on a group, and you are behind them, it is almost always WORTH to turn into a Brood and fight. Inactivity as a Brood is annoying for your fellow alien players, will lead to a round being drawn out longer than is necessary, and may lead to a lame duck situation in where there are a large group of humans, and nothing can be done to kill them off. When traveling long distances or in an end/late game situation, going into Brood form and sprinting to find humans or get to a human filled location is a great thing to do.

At the start of the round you may want to consider grabbing a lightweight weapon, such as a smg or pistol, instead of something heavy, such as a Tesla, rifle, or shotgun. Reason for this being you will not attract suspicion if you have a weapon with you, along with if you ever need to be in human form, you will have MOBILITY. This means if you need to get behind someone very quickly as a Brood, you spend less time doing it (assuming they have a rifle, or more than that.) Think about the available strategies you have at your disposal, for both the map you are on and the players you are up against. If people are grouping up, get a grenade or a medkit. If people are denying nades, find some and put them in a vent or location that you can come to later. If people are splitting up in groups of 1s or 2s, get a medkit. If you decide to go down the inefficient route of deception and find a group of humans to group up with, consider getting a glow stick, and have a fellow Brood or Swarm turn off the lights. You decide what to do. Other considerations to think about would be to deny a high powered weapon by getting to it, getting the ammo out of it, and placing it in a vent.

The art of drawing fire is a simple action to do. This involves the Brood briefly going into the vision of a human then out behind a wall. The human will obviously start shooting and waste quite a bit of ammunition. The Brood can dart back in for half a second then out to bring on another round of wasted shooting. Often times the human will go on the aggressive and chase the Brood. As a Brood you can chose to circle strafe or back away from the human and wait for him to waste his ammunition to kill him, if you have a few Swarms or Broods with you, you all can choose to Swarm him as he comes around the corner. There is also something called shoulder peeking, where instead of your whole body being shown you show part of your shoulder instead. I do not believe that I can explain shoulder peeking the best, so at the end of this guide will be a video detailing it and many other things. This advice is very applicable for Swarms too.

One thing to note is if a Swarm is drawing fire from a group of humans it’s a great idea to, instead of shooting the Swarm, press v to turn into Brood form and attack the humans at their backs. Along with that, if you are walking towards a room with a human in it, and a Swarm is with you, TURN into a Brood and kill the human. You will almost always survive through 1v1 conformations and considering you have a Swarm with you, the odds become a whole lot better in a 2v1. You have the numbers advantage! 2 aliens are always going to kill 1 humans, 3 aliens are always going to kill 2 humans. Do not shoot the Swarms too, or kill them for that matter. The game is meant to be played as a Brood in Brood form. Depending on the server you will lose sanity for shooting and killing a Swarm.
Keeping the lights off is an important thing to do for an alien victory. It can help in the aid of surprising and killing humans, along with having them to make the difficult decision of carrying a glow stick or medkit. If the humans decide to use the glow sticks, press e on the glow sticks thrown out, either as a Brood or Swarm. This will destroy the glow stick and the light advantage gained from the glow sticks will be short lived. This is an important bit of knowledge to know as a Swarm too. If you are going in to attack a group of humans in a room, they will most likely throw a glow stick at your location. Press e on the glow sticks. As you go into the fortified room, press e on any other glowsticks the humans have. One thing to acknowledge is that Swarms are seen easier in the dark, thus it will be easier to shoot them down.

If you were recently infected and there is a group of humans incoming, press v as soon as you spawn, hold onto shift, and sprint out of there. From that point on, assume that every human knows that you are a Brood. Stay in Brood form, try to find a nade, try to find pickoffs (find a loner, groups that have a hurt person, people on the edges of the map, people or groups of 2 doing needs, etc.) and open all vents you see. If you were infected with no one around, get a lightweight weapon, and decide if you want to get away from your body or patrol a large area around it (in either Brood or human form). If others were infected with you, it’s a very good idea for one Brood to patrol the area around the bodies. If you see anyone in your smell range coming your way, assume they are going to get to the body's. When that happens, you make the judgement call whether or not to engage them. If you decide for whatever reason to stay with a group, assume that at some point they will find your body or people will come into the group at a later point and kill you. I would not recommend staying with large groups of people if you are a Brood that died a while ago. If you get killed in human form, its not rdm, its a case of those humans finding your body.

As a Brood or Swarm, it's typically a good idea to open all closed vents. Reason for this being if you need a route to escape in, the vents are a great way of escaping from humans, along with being a great place to stash an item or two to use later. I cannot stress the usefulness of this enough.

On using guns as a Brood: The game is not meant to be played using guns, considering as Brood form is the way to go and you are punished for using guns and such. Brood damage is cut by 33 percent for using guns and there is a sanity loss associated with using guns, unless for some odd reason the server has it disabled. Using guns is an unskilled way of playing of playing Brood that has no place in Morbus, and if a certain situation forces you to use a gun because of how the map is set up, that is by fault of the Map Maker. Getting a nade or having swarms take out the target is a better option.

As a Brood, the medkit and the frag grenade will be the two most important items you will be using to win your round of Morbus.

The act of frag grenading a group of humans is an amazing play to make. The strategy is to find a nade, find a group of humans, left-click to throw the nade, and as soon as you throw the nade, press v to turn into Brood form, run behind some cover, and watch as a majority of humans get infected by the nade or very hurt. Come back in to clean up the hurt and shocked humans. A variation of this strat would be to go up to a human doing a need, right-click the nade to drop it instead of throwing it, press v, then run away. If you cannot find any pickoffs, all the humans are too grouped up and are managing to dodge your nades and you need to create momentum to win the round, doing the variation is very useful and worth. Unfortunately, with Demonkush’s Gamma Update, this tactic has been indirectly nerfed, with the addition of other nades that do a variety of other effects. Learning how to draw and waste Human fire is a valuable tactic to know now.

Playing as a Swarm is the easiest class to play as, but is the hardest to master. Running at humans and using left-click to use claws and right-click to spit is the simple gist of playing as a Swarm, but to play as the best requires good game sense and good judgment. As a Swarm in the current meta of Morbus you are capable of 1v1ing a human and winning it, or at the least dishing out a lot of damage. Your job is to open up vents, draw fire from the human and waste their ammunition, dish out damage to multiple people with your spit splash damage, make space for your Broods, protect them, take out the lights, protect dead bodies, find any lone humans and pick them off, taking out any glowsticks, etc.

In the Gamma 2.1 update and 1.5.7 update, there is the addition of a Swarm Upgrade tree. This makes the swarm very simple to play. The only upgrades really worth getting is Chemical Bomb and then Demon Flare. Depending on your play style the Swarm Haste upgrade would be a nice one. Nitro core is an amazing ability that stuns a human for .5 seconds. It is THE counter to the blaster/any weapon that lets a human have a high amount of mobility.

Medkits are very valuable for Brood aliens. 150 points of healing for something that is capable of having 220 max hp is just invaluable. The fact that broods have a max of 100 HP in human form make medkits much more efficient. Medkits allow a Brood to go into a group fight with the knowledge that they can just as quickly dart out, heal up, and dart back in. This leaves Humans with barely enough time to heal to 100% and reload all of their weapons. Medkits save Broods from going points into Regenerative Tissue, and instead spend points in Sharpclaws or Defence Carapace. Having a medkit also means that 150 HP is denied to the Human side.

Aliens should win 90% of the time. The nature of Brood Aliens make them very easy to snowball with, and if three humans are killed off in the very starting stages of a game, any decent player will be able to close off the game and win, no matter how many other humans remaining there may be. Swarms are also very OP in the current state of the game. The alien upgrades added in make it even more so. If you want to learn how to play as a Brood, take time to play as a Swarm without any upgrades.
Adrenal Claws:

Putting points into Adrenaline Glands and Sharp Claws will give you both a great amount of speed and damage, but ignores points in Defence. Light control is truly needed in order to play this effectively, and only certain portions of certain maps are able to properly be taken advantage of, the main example being the lower levels of mor_spaceship. 4 points in sharp claws, 1 point in sprint is the way to go, or 2-4 sprint, 1-3 points in Sharp Claws. Speed is a huge part of this, and just having 1 point in sprint may not give enough of the necessary speed. At the same time, while 1 value point in Sharp Claws will make you be able to kill humans with 1 less hit, the 2nd and 3rd points in Sharp Claws don’t really do much in terms of shaving off a hit, while the 4th point will let you kill a human on the face with just 5!! hits. With the cover of darkness, this is a very scary build to go against, but can be negated with a high powered weapon, such as a shotty, or by detection, such as a glowstick. This could also be considered a really nice Cheese tactic vs higher level players.

Build involves getting 4 points in SharpClaws, 1 in Sprint, 3 more in Sprint, into getting Defensive upgrades or getting Relentless Attack.


Getting 2-3 points in Sprint, 1-3 in Sharp Claws, into getting Sharp Claws total 4 points, into getting Defensive upgrades or Relentless attack.

Invis Brood:

Involves putting points into the Utility tree and getting the invis upgrade. Getting points in the Silence is optional. Stand still to go into Invis. Very useless Build, only useful if cheesing ‘pros’ or vs Newbies, or if your name is Brother Frank. Its very easy to reveal, all a player has to do is put their laser sight on you, or spray a whole room with bullets. It gives you nothing if you are unsuccessful and people are doing needs in groups. late game, if people are in groups, you have no way to combat them, with you having no points in defence or attack.

Skilling involves getting 3 Tier 1 utility upgrades, into 1-2 points of Adaptive Carapace, into 1 Softened Breach, into maxing Adaptive Carapace, into getting 1 point of Strengthened legs, into getting 1 point in Sharp Claws OR maxing Defensive upgrades.

Attack Brood:

Involves putting points in Screech, 2 points in SharpClaws into 2 points in Relentless Attack(attack speed) into maxing either Sharp Claws or Relentless Attack, OR getting 1 points of Enforced Scales into 2 points of Def Cara into the rest of Defensive Build. Ok build, really great for cheesing. Main tactic is to get behind someone, press v and kill them near instantly. The screech will Blind them and make them unable to respond for hopefully the duration you are attacking them. Problem with the build is that it is a horribly inefficient starting build; the second point in Sharp Claws doesn’t kill anyone faster, you're putting a point into freaking screech, if you are unable to get close to another human or mess up using screech, it is a wasted ability in most scenarios, exp the late game.

Most decent players will also note where you are before the screech, and will try to protect their backs. Screech could be better be put into other things, as late game it is better to stay in Brood form and Screech is a crutch ability. (I do not find many higher skilled players use it, except in a few rare cases.) Relentless attack is also a bit odd, for a number of reasons. If you kill a human in three hits, with two lvls of Relentless attack it will take you 1.35 seconds to kill them. With no levels in it, you take 1.65 seconds to kill someone. It saves a grand total of .3 seconds! With 6 attacks, 2.7 if you upgrade it to level 2, and 3.3 if you don't upgrade it. .6 seconds saved! Another thing to consider is that hits may not always register due to the normal 33 tickrate that most Gmod servers have. I do not think that the small savings in time is worth forgoing defensive abilities for.

When you use a build often, I recommend at one point to do some math on it and see if it is efficient.
The human side has many disadvantages that are hard to overcome. The aliens will win IF the person playing as a Brood knows how to play. The human side of things will require you to take advantage of any mistakes that the aliens make. You will be hunted all throughout the game, but that does not mean you cannot hunt a Brood down your self.

Medkits are a great item to have 100% of the time. 150 HP can be healed with just one kit, and with it being very lightweight you can always be on the aggressive with them. It is NEVER a wrong decision to have a medkit. Let me repeat that. IT IS NEVER A WRONG DECISION TO HAVE A MEDKIT. Grenades are not very useful in the early game, considering there are few to no Swarms in the early game. Glow sticks are not very much needed unless you are a bit far away from the light switch, and the lights happen to go out. Even then Medkits are better. There are two kinds of glow sticks, the glow stick, which is green and radiates light in a wide radius, and a sticky glow stick, which radiates light in a smaller radius, but can be put on walls or ceilings. The Gamma Update adds a new type of glow stick, the Grav Glowstick, which floats in the air. If you are in a group, two medkits and one glow stick/frag grenade is a good composition for a group of three humans, but I’d argue that having a third medkit is still a good idea.

Weapon selection is a decently important choice. A low rpm but high damage weapon is good in the early game, but will fall off later on in the game as the amount of Broods with damage resistances increase. Another thing to note that they are more efficient at killing unupgraded Broods and Swarms. Weapons with a bit lower damage but high rpm will be OK early game, but will be better than their higher damage + lower rpm counterparts later on in the game. Reason for this being there will be more Broods with damage resistance upgrades and the higher damage weapons with lower rpms will decrease in power, along the fact that those weapons will usually have a low amount of ammunition, such as the UMP. The lower damage weapons with higher rpm will usually have a larger amount of ammunition, like the Vector and R22. This allows you to sink a larger amount of ammunition into a Brood, at a faster rate. The situations where you have to reload during a fight against a Brood will be minimized. While Broods can counter the damage of guns, they cannot counter the high rpm or high amount of ammunition. If you are to be stuck with a gun for a whole round, make it be the Vector or R22. If you are OK with changing weapons mid round and taking out all the ammunition in your gun, get the UMP, then move on to the Vector or R22. If you are in a group of 3-4 group situation and ammunition for smgs are coming hard to come by, consider having an ally hold a UMP. This section applies mainly to the SMG class of weapons.

The true rifles of the game are decently balanced. The only one I would not recommend getting would be the LZ400, as its low ammunition and it's low damage (14), along with the 22 KG for a weak weapon make it not worth it at all to hold and a trash tier weapon. If you are to choose, get either the SC7, the M418, or the KA47. The SC7 and KA47 have the same rpm, but the SC7 does 2 points of damage less(17), weighs 23 kg, and is a bit more accurate. KA47 does 19 damage per shot, weighs 24 kg, and is a bit less accurate. The M418 does 16 damage, has the fastest RPM of all Rifles, weighs 23 KG, but is very inaccurate.

The other weapons that take up the rifle slot vary in power level. The Tesla, a laser weapon that shoots very slowly and does 1 shot kills on unupgraded Broods and Swarms, sucks, as its high weight, VERY low RPM, and its rare ammunition make it a trash tier weapon. There are certain servers where the Tesla has a reloading glitch where if you press r, the tesla will be ready to fire again. In this case, the tesla becomes viable. Outside of the reloading glitch, if you ever want this weapon in any situation, it would be if you have no other weapon to use or you are in a group situation where you want to kill Swarms without using SMG or pistol ammo. I would argue however that there are better weapons than the Tesla to use for killing Swarms.

The HMGs are very powerful, and I would argue that they are among the 3-4 most overpowered guns in the game. The ZX9 is the most powerful of the two, with it having 200 bullets in reserve, 50 KG, low recoil, and 14 points of damage. It is possible to walk around with this weapon and kill many things in sight. The Bulldog, the second HMG, is the weaker of the two, or rather has fewer benefits. While it does 20 points of damage, it is far more inaccurate, weighs 5 more pounds, shoots a lot slower, and has only 100 ammunition. If you are able to, get the ZX9. A few things to acknowledge about the HMGs is that they don't need reloading and they cannot be reloaded. It’s possible to ‘Kill’ the weapon by unloading the ammo, rendering unusable for anyone else that comes across it. It's decently easy to get hits if you shoot in bursts or spray control the weapon. The Scar M8 is a shotty, and is the most powerful of all rifle type weapons, and the second most overpowered weapon. It shoots once per second, has 11 pellets in a bullet, and each of those does 9 damage. Despite the fact that it should do 99 damage total, it does more than that because of the game adding damage it self. It’s capable of 1-2 shotting a Brood with just 2-3 points in defense carapace. If a target is far away, iron sight the weapon to snipe them down. A Brood has to get Enforced skeleton and Endurance in order to counter the shotty effectively.

The SMG class of weapons have very weak weapons, except for the Vector and the R22. The Vector does 11 damage, has a very high RPM, is 18 KG, and is very accurate. The Vector is the strongest and most useful of all the SMGs. The R22 has 13 damage, a negligible RPM decrease, 15kg, and a bit less accurate. UMP would come in third, with its slow rpm and low ammunition holding it down, but its high damage is good for the early game and vs Swarm. U8 Gauss SMG has low damage and RPM, but it has one strat where it is viable: the high amount of ammo that this weapon can carry makes it great if there is someone using a tesla or blaster. When they have expended their ammunition, simply unload the magazine, and the energy ammo will be replenished. The UZI is only decent as a "panic" weapon, with it having the highest RPM in the game, but a horrible spray pattern. As of the 1.5.7 Update, the uzi weapon is nearly trash tier, with its unique feature of having the highest rpm being removed.

The pistols in the current meta of the game are not very useful. The Beretta is too heavy for its nonexistent usefulness, having too long of a load out and reloading time, low rpm, and low damage compared to other pistols. In the 1.5.7 patch, the Beretta has its weight reduced, but its ammunition capacity is reduced from 15 to 8, making it a weapon that is never worth getting. P299 and the USP are OK, they do the most amount of damage of all the pistols. If you want the most bang for your buck with a lightweight pistol, get the P229, as the difference in damage between the USP and P229 is 22 to 21, and the differences in accuracy do not matter too much in a fight. The JV Phaser is near useless.

Now the Blaster is leagues away from all pistols and even all weapons. It is the most overpowered weapon in the game. The weapon does 18 points of damage (and that is according to the ingame files and not ingame), is VERY lightweight for its killing power (Just 7 Kg!), has a fast reloading animation, and has an AOE. This AOE is the most unique aspect of this weapon. The area of effect damage is capable of wiping out multiple waves of Swarms and Broods together. Any fellow humans stuck in the crossfire of this weapon will similarly be done for. All that needs to be done is aim the weapon somewhere near the enemy, most beneficial in the path of where the enemy is going, and shoot multiple times. The AOE effect will do the work and blast the aliens into the air, immobilizing them for a second. It is very hard for the aliens to counter, as you need more than 1 point in the enforced scales upgrade in order to counter it. You need multiple Endurance upgrades, along with multiple Defense Carapace upgrades. The AOE does not damage the user using it.

As a human, I would recommend doing needs as soon as you get them. There is an argument to be made by the opposite side that "If you wait, you will not have to do a need for a very long time." While partly true, there is the possibility of a group of Broods or Swarms coming over just as you need to do your need. There is also the problem of you sitting put, doing nothing. You could be spending the time waiting walking around finding bodies, killing Swarms, grouping up with other humans, or helping others do their needs. While I think camping is a great tactic to use as a human, it isn't the most effective if done in the early or mid game. That being said, if there are Swarms or Broods around when you need to do a need, it's best to take care of the threat, then do a need, considering that it heals a part of your HP.

If the lights go out during a game, it’s best to turn them back on as soon as possible. It is best to go in with a group, but if you do not have one, proceed with caution. If there is a Brood, shoot it and turn the lights on, if there is a human that turned the lights of, proceed with caution. On some servers, it’s kos'able for turning the lights on and off whether or not you are a human or Brood. Having medkits in a “Lights Out” situation is often more preferable than having glowsticks.

If you or your group does not want to go to turn on lights (despite that, holding out in a light switch room is often better), defend all entrances and exits. If you have glow sticks, place them near a person's position, on a prop, or a bit close to an entrance. When placing glow sticks, it’s important to note that you want to place them where a Brood or alien either can't get to them, or they have to be within sight of being shot for a couple of seconds. Placing glow sticks on props may force the alien to jump on top of the prop in order to get it, along with that, some props may get the glow stick stuck under them or get the glow stick wedged in between the prop and the wall. Place stickly glow sticks(the orange glowsticks) on ceilings instead of walls or the ground. You can also place a sticky glow stick on a crate of ammunition, and it will be impossible for a Swarm or Brood to eat the glow stick. Place one green glowstick near the middle of the room you are defending, and near the spots that a defending human player is standing on. The normal glow sticks make decent offensive glow sticks, with their only problem being they may roll closer to a exit, making it easier for an alien to pick it up. Glowstick light radiates through walls, so it doesn't need to be in front of a door or a vent. If you have frag nades, throw them when you think there are a large amount of aliens outside.

If you are in a group, make sure no one falls behind, make sure everyone has a item, and mark people in your group as friends by holding onto tab, clicking their name, and marking them as a friend. If you are attacked by a Brood, back up into a wall or close to a fellow human, and don't let the Brood force your fellow humans to shoot at an angle that will make the bullets hit you. If your fellow human is being attacked, you have a small number of options to do. You can move in the barrage of attacks that the Brood is giving out, and tank some hits for your friend, if you are shooting the Brood, shoot at an angle at the lower legs or feet of the Brood. Try and move to the side of your fellow human and shoot the side of the Brood so your ally is not in the line of fire.

When defending a location and a Swarm is shoulder peeking your group, you have two options. Do not waste bullets on it till it shows its whole body, or shoot its shoulder and run after it. The 2nd tactic should be used when the Swarm has been spitting your group down. If there is a chase after it, the whole group NEEDS to be right behind or beside you. When chasing someone, even if it is a lone Swarm, the whole group needs to move as one, or risk having one human die. Likewise, if you have a need to do, splitting off from the group can lead to Human side losing the game, in certain situations. The biggest one: When Aliens Side has no Swarm respawns left, and there is only one Brood around, one death can lead to there being 3 addition Swarms being out on the map, 1 more Brood, and 1 more upgrade point for a Brood. I cannot count the amount of times Human side have lost due to one human splitting off from the group and dieing, leading to a gain in momentum to the alien side.

When you are playing the game, it is important to note who is a friend, and who is foe. If you see someone do a need, mark them as a friend if you stay with them, or as suspicious if you or they walk away, reason for this being is if you see them later, you know that you've seen them before, but they may not be the most trustable. You can retrace the path that the human went through and see if they died or not. If you heard a Brood nearby, and see a human come out of a door as it stops, feel free to mark them as caution.

When a fellow human is doing a need, defend them. Find a spot to defend them from. Some need props on some maps you can jump onto (such as the PTMC, Alpha station, and Facility showerheads, the Breach Bunkbeds). Defend your teammate from there. If you're doing a need with a friend ask that they protect you. If you are by yourself, and you know a Brood is following you or a Swarm is, and you want to buy yourself some extra time, throw a nade and do your need. The sound of the nade may cause the person to get back. Nades take about three to four seconds to explode, so you may save yourself that time, plus the time it takes them to get to you and start attacking you. This tactic may not work often, and should be used if you have a nade and as a near last resort. One thing to acknowledge is that you can reload weapons during a need. If you are doing a need, put your back to it and press e. This will make sure that no brood can do double damage to your back, and you can fight back as you finish the need.

Winning as a human with a skilled group of Broods is very hard if not near impossible. The blaster may be the 1 weapon capable of winning the game single handedly. Like said before, you need to hope that the Brood(s) playing make mistakes and you capitalize on those. Move around the map and find friends and bodies, and maybe even camp up till the round ends.
This section of the guide prolly only applies to players that have played the game a decent amount, are good at the game, and looking to move on to the next level of playing the game.

Morbus at its core is about the war of attrition between Human Side and Alien Side. Human Side is marked by a gradual weakening in resources (ie medkits/ammunition/glowsticks/flashlight battery/anything that can be used in human form.) and in amount of players. Information is lacking for the Human side, there being no built in way of knowing who's around you or what is going on around the map. Based on this info, the best way to play this game is not to wait 10 minutes for the evacuation win requirement, but rather to move around the map, gathering info on the current state of the game (who is going where, doing what, amount of resources left on the map, who is alien) and gathering resources if there is a depletion of any.

Alien Side is marked by a snowball increase in power, with the advantage of swarms, getting upgrade points for every kill a Brood gets (which is also distributed to other Broods on the map!), and an increase in the amount of players. The affect of attrition on Alien Side is less marked, them having fewer different resources to choose from (time, medkits and frag grenades vs Human side who needs ammunition and weapons, in addition to medkits and such.) and swarm lifes. Being in human form is going to be inefficient, fact of the matter being that aliens cannot snowball if they kill while in human form, and Brood form is going to offer a whole host of advantages (Brood noise creates pressure around the map, mobility, killing power, ability to soak up bullets.). Vs Humans, the best tactic is to make the effect of attrition pronounced. This is done by staying in Brood form and creating pressure all around the map, via means of your presence, turning off lights, extreme mode of mobility, killing Humans in Brood form.

The concept of map pressure is an odd one for some to grasp. If you are a Brood that is in human form with humans, your contribution to the game is non existent. If you are a human camping in a room at the start of the game, your contribution to the game is small. If you are roaming around the map as human, you are able to have a large impact on the status of the game, you are more likely to come across bodies, be able to react to a Brood killing humans, limit the number of swarms and Broods on the map b/c you have info on who is a Brood or not. Your movements, depending on what weapon you have, the amount of people with you, and a few other factors, can limit the Brood movements across the map, may be even blocking off a portion of the map for Alien Side, and can limit the amount of resources that a Brood can have access to. As a Brood, if all the people I infect are killed after I infect them due to a roaming Human, I am very scared. Even if you are roaming in a section of the map where nothing is happening, you have info that action is prolly happening in another section of the map.

For every Brood thats killed, Human side gains back a small advantage. Every swarm life that brings the counter closer to 0 is an advantage for the human side. Saving a human life is an advantage to the Human Side, the Alien side gets 0 points and is less likely to snowball. Information acquired is information that can be used to win games. The chance to kill an original Brood tilts the game heavily towards Human Side. The concept of roaming and creating map pressure is incredibly OP, but only if the player knows how to force things into their advantage.

Alien side can do the same. Turning off lights forces humans to group up and camp up, or to funnel away from the area that has lights turned off, or towards the light switch. Forcing movement is incredibly strong, as this leads to more opportunities to picking off humans and forces humans to use resources while lights are out. Brood form can deny access to resources for Humans, with a huge cost involved if the Human side wants to acquire access to the resources.

Map Control of a certain area of a map is another important concept to grasp, which can . This can be seen in Facility_b2, if humans have control of the top half of the map, their chances of winning are heavily increased. Brood aliens have only 2 points of access, while swarms have to hope for a spawn that is favorable, but even then the Human Side can counter that by killing swarms as they come out of spawns. In Isolation, if humans have control of the central area of the map, Broods can not move from Bathrooms to Shower/Beds or Vice versa. Broods then have to use the upper portion of the map in order to move around effectively, which wastes time.

Time is a resource / source of info that valuable if noted and used effectively. Over time, you start to note timings of certain things, such as “If I walk from shower to piss with a shotty, it takes approximately 30 seconds to get there.” If a Human comes back from piss within 45 seconds and claim that they had done the need, you would know that would be a lie, as the round trip should have taken about a minute, + 8 seconds of doing the need. If there’s something that the current ‘pros’ don't apply much of in game, this would be a close 2nd. It takes time to notice how long it takes people to move place to place, and its mostly an ability that requires playing the game a decent amount while consciously thinking about it, along with noting the different weapon weights. Building this skill/mental map of noting where people were, and are going to go and how long they are going to get there, and predicting where they will go next or what actions will happen is prolly the most valuable thing a player can practice/use. If your a brood, its worth noting the cooldown of your transformation (10 seconds ) and the reload timing of weapons.

Healing is one of the most important things in the game to be done, but there are multiple complexities associated with healing that if executed mostly right, can be the major contributing factor to a win or lose. The basic strategy of healing is to just heal the fellow members of your group. This alone is only thing some players need to know about the strategy of healing.

The problem with this strategy is that it assumes that the game revolves just around your group, rather than the Alien side and other humans. My ‘style’ of healing accounts for the problems. The theory behind it being the game is a system. Other humans and Aliens exist in the game. Other groups of humans are resources for both my group and alienside. Groups that are hurt are likely to be farmed on by Alien Side, which gives them the resource advantage. Having multiple groups of healthy Humans is going to make it so that each group has a large amount of map pressure, vs one group having full hp humans and rest groups having low hp characters. Healing people from other groups is a kind of investment, in that they are more likely to kill a Brood or swarms than if they were low HP, they are able to stifle the Alien Side growth in addition to my group. They in time, will be able to lower the amount of resources that my group would have to use late game, and they themselves will be able to find more resources. Aliens stay weak and limited, while Humans stay stronger for longer. Following this, it would be in my best interest to heal people from other groups.
There are a fair amount of issues that pop up, ofc, like if you accidently heal broods, if the people that you heal die a little while afterwards and dont kill anything with them, then your healing was wasted, there is also the limiting factor of medkits around the map, which is remediable if the rest of the group carries Medkits that they can drop when yours is gone. This tactic can also starve the map of medkits, which can be good or bad thing depending on the situations (examples, a brood is trying to find a medkit, on the other end, a human is trying to find a medkit.) Another factor to take into account, this skill set makes you win games, but doesn't get you any Gametracker points, so it might not be worth investing time into figuring how to do it.

Swarm is undoubtedly the most ‘OPest’ class in all of Morbus, more so with the addition of the swarm shop. Swarms are the ultimate source of attrition vs human side, as they take alot of resources to take down, more so than the concept of them should. A swarm will be able to do alot of dmg in a 1v1 situation, and can end up killing the human if the human is severely unskilled. Swarm haste makes the amount of ‘space’/’baiting’ even bigger, the nature of mobility being that they can waste resources without being hit.

If you want to practice/learn the concept of map movements/how you yourself can influence movements, Spam Swarm and Blaster (play alot of swarm and use the blaster when human.). Swarm teaches you alot of the game on a conceptual level, and whenever I’m trying to figure out the game/ coming back from a hiatus, swarm always helps me to understand the game. (type kill into console at the start of a round if you are human.) Blaster creates alot of map pressure as a weapon, it being highly mobile and having high damage output, when you use it, smart Brood players will know to avoid you.

If there are maps that you want to practice your game sense/understand map movement/pressure/control, play Chemical labs, undoubtedly the best map for practicing that stuff. Breach is another good one, just b/c of how the map revolves around 2 areas and 2 pathways and the abundance of nades and medkits. Facility is great after you’ve practiced, in that you can put alot of the concepts into good use. The low amount of medkits are good for practicing good habits.


Morbus is a simple game revolving around a Mafia or Werewolf style of game. While simple in explanation and appealing to a causal crowd, it is also accommodating to the competitive crowd, with there being many tactics and strategies that can be employed. A decent majority of these have been discussed in the guide already, such as using Grenades as a Brood, how to play or what to do as a Swarm, or how to go about being a Human. Other topics, such as how servers should be configured, thoghts and considerations to take when mapping for Morbus, or KeyBinding Brood/Swarm upgrades, will be covered in Part 2 of the guide. How to play maps and how to access secret rooms will be covered in a Part 3.
