The game's standard zombies; grunts are easy to kill, but are everywhere, being especially prevalent at the points of interest where the clues and bosses are found.
- Glass Cannon: Zombies are extremely weak, but the ones armed with blades or torches can seriously mess you up if they do manage to land a hit on you.
- The Goomba: They're pretty much cannon fodder, but can seriously mess you up if they catch you unawares. Fighting them is also a good way to alert nearby players of your presence.
- Hive Mind: One of the journal entries in the lore section seems to imply that the zombies might all be "puppets" of a single otherworldly force.
- Our Zombies Are Different: Grunts are essentially zombies in everything but name. What type of zombie isn't exactly clear as the nature of the demonic invasion. So it could be some mix of Voodoo Zombie,Plague Zombie, Parasite Zombie, or Possessing a Dead Body zombie.
- Flesh-Eating Zombie: Grunts can be seen hunched over dead bodies strewn across the map presumably consuming their flesh.
Zombie dogs. Hellhounds are remarkably fast and can be deadly if they catch you unawares or in a pack.
- Fragile Speedster: Hellhounds can't take much damage, but are the fastest enemies in the game other than the Spider. Also, they can really mess you up if you fail to get a headshot on them.
Zombie women who have become a nest for poisonous flies. If they detect you, they'll unleash a cloud of such flies which will attack you and drain your health for as long as you're within range of the Hive.
- Chest Burster: While we don't actually see the chest burst occur. It's implied that that's exactly what happened. As a truly massive hive appears to have ripped true the hosts chest so severely as to rip their entire chest open and all but snap the poor host in half.
- Half the Man He Used to Be: The host is bent over backwards with their ribs ribs horrifically exposed: practically cutting the host in half.
- No Ontological Inertia: Blowing out the host's brains instantly gets rid of all the flies as well.
- Synchronized Swarming: The Hives go to attack. The Hives are massive walking hives of demonic insects and if they see you they'll send them swarming at you.
- Roar Before Beating: When the hives see you they let out a blood curdling screech as their swarms make a bee line for whatever hunter got to close.
- Wicked Wasps: While the bugs swarming at you aren't clearly visible they appear to be some form of wasp. And the hives sticking out
Tough zombies who have developed bony plate-like growths all over their body. They can take a lot of hits and are surprisingly fast.
- Heavily Armored Mook: As their name suggests, Armoreds are covered in armored plates and can withstand several shots from most weapons. They're also tough enough that the amount of melee hits needed to kill one is more than your max stamina will allow, unless you use the most powerful melee weapons like the axe or sledgehammer.
- Kill It with Fire: One of the more effective (and least loud) ways of dispatching them is to set them on fire, such as with a thrown latern, molotov cocktails, or the flare gun.
- Knee-capping: Since Armoreds can outlast your stamina and can even power through lower caliber bullets to smash you in the face, one of the best ways to deal with them is to strike them in the legs, which cripples them and slows their movement to a crawl, making them significantly easier to deal with.
Large, burly, headless corpses controlled by a colony of maggots, Meatheads are the largest and toughest non-boss enemies in the game. They are blind and deaf due to not having a head, and have a symbiotic relationship with the large leeches that swarm around them, serving as their eyes and ears.
- Giant Mook: Meatheads tower over regular humans and can take a lot of hits; they're about 50% tougher than an Armored.
A swirling mass of swarming leaches and hatred that patrols the waters of the Bayou, ready to shred to pieces any unfortunate Hunters or Ducks foolish enough to wade through its watery territory.
- Hazardous Water: Type 3. It can be difficult to see them in the water before they realize you're there. But when they do...
- Instant Leech: Just Fall in Water!: The Water Devil may look like some squid or octopus out of hell. But this thing is a leech, and originally was going to be just one massive leech instead of hundreds of smaller ones.
- Jumping Fish: Well sort of. It's more like Jumping Leeches. Once a player enters into the Water Devil's territory they will swarm out of the water. Leaping in and out of the water towards the player giving the appearance of a large angry squid rushing at the player tentacles first.
- Lightning Bruiser: Water Devils do massive damage, can survive almost as much punishment as Armoreds, and are incredibly fast. The best way to deal with them is to just not go into the water if they're around.
- Night Swim = Death: if you're doing a nighttime mission these enemies can become this.
- Piranha Problem: Well leech problem really. None the less the water devil functions exactly like a school of starved piranhas. Swarming at the player, or the occasionally unlucky duck, once within range.
- Synchronized Swarming: So much so that the Water Devil is confused for a single tentacled monster and not a swarm of around 150 serpent like leeches.
A particularly large and tough Meathead with a hook for a hand and a pig's severed head mounted as it's "head". The Butcher can turn its hook hand red-hot, allowing it to throw flames. While it is not out right stated it is strongly implied that the Butcher was the old owner of the Slaughterhouse.
- Axe-Crazy: Even before becoming the Butcher Young Roche wasnt exactly a stable person. Many of the locals were of the opinion that he was more interested in the killing of animals than the raising of them. And when the Slaughterhouse Monopoly and the local traders put him out of business he went off the deep end.
- Attack Its Weak Point: Averted. The Butcher has no weak point; its "head" is purely a decorative ornament. You'll just have to defeat it with raw firepower.
- Bizarre and Improbable Ballistics: Instead of lobbing his fireballs straight at you, the Butcher throws them in a wide arcing horizontal curve. This can occasionally catch you by surprise in wider open areas, but in the tight corridors you usually fight him in it just means he always ends up hitting the wall next to him instead of you.
- Damage-Sponge Boss: The Butcher can take 30+ rounds from pistols or the Winfield rifle variants before going down. Even the Nitro requires 8 shots to put him down; double that for the Mosin-Nagant or Sparks long rifles.
- Kill It with Fire: The Butcher has supernatural control of flames and will attack you with fire attacks; naturally, it is also immune to fire damage.
- King Mook: The Butcher is basically a really large and tough Meathead that's not blind/deaf and has the ability to throw trails of flames.
- Mighty Glacier: The Butcher is faster than he looks (at full charge he can keep pace with you even when you're sprinting), but is still relatively slow compared to other enemies, especially the Spider. However, he's the most durable opponent in the game, with roughly double the health of the Spider and no weak spot to target for massive damage.
- Was Once a Man: It is strongly implied that the butcher was the owner of the Slaughterhouse, Peter "Young" Roche.
A multi-legged monstrosity that resembles a giant spider, although closer inspection reveals its "legs" to be twisted human limbs and its "face" to be a skinless human head.
- Big Creepy-Crawlies: Oh boy, all those with arachnophobia best steer clear of this boss. As the name implies it is a giant spider like monster.
- Fragile Speedster: The Spider is incredibly fast and moves in a very chaotic manner, however its offensive abilities are limited. It can spit poison, which blurs your vision but doesn't actually deal much damage, or it can pounce on you, which deals decent damage but is heavily telegraphed and easily interrupted. For the most part it primarily wastes your time as you chase it around its arena, giving rival hunters an opportunity to find and kill you.
- Painful Transformation: What ever made the spider what it is couldn't possibly have been a pleasant experience.
- Roar Before Beating: The Spider will stand still, rear up on its legs, and hiss at you before using its pounce attack. Damaging it when it does this will interrupt its attack and cause it to run away.
- Was Once a Man: Well based on the "face" and it's legs yep this monster was once a human being.
