About this game
Aliens have finally invaded, loud, mean, and not here for us. Earth has been scorched, defenses are obliterated, but the war isn’t over. What are the invaders after?
You are a C.U.S.T.O.M. soldier, engineered with the perfect balance of strength, aggression, and stupidity. Fuse with Animal Genetics, load up on high tech weaponry, and run throat first into danger.
Blast your way through sewer scum in New Los Angeles to the bloodied snows in Antarctica and more! Which timeline will bring forth the truth?
Clear waves, choose mutations, and morph your DNA to the extreme! Stack damage, hoard HP, size up your bullets, and more. Special gene augments crank your Animal Genetics to their evolutionary breaking point.
High-speed nuanced twin-stick action with melee, dodging, grenade cooking, animal DNA, and endless augment combos. Every button counts and every move has teeth.
Whatever keeps you alive is allowed, despite what Geneva says.
Mod your weapons on the fly, pick the affix that fits your attitude, and become the problem. Master the Animal Power that accentuates your playstyle, because destruction should be custom-tailored.
On your missions through space and time, perfect your genetic signature until you’re a walking war crime.
Squad up in 4-player co-op with your emotional support gremlins and jump right into the action. The game scales with your crew, so every run hits hard, stays fresh, and keeps you coming back for more.
Perfect for tryhards and button-mashers alike because death’s a lot less lonely with friends.

Your voice shapes the game. We listen, tweak fast, and update even faster.
Join early. Make it yours.
Dive into the lurch with ever changing paths of chaos, making every run unique. Pull the thread with help from unlikely allies. Will you merely scrape the surface, or delve deeper into the conspiracy? Every run brings you closer to the truth!

NUKE the Anunnaki in the BALLS now!
The pyramids are ready to reveal their ancient secrets.Battle through alien hordes to hunt the Anunnaki.This update is an absolute unit of content you can chew on for hours, from new pyramids to fighting Anunnaki gods, to a complete overhaul of the UI and a brand new permanent progression system. There is so much to explore and explode, let’s talk about it.PyramidsThe ancient structures await, packed with brand-new challenges, stunning vistas, and boss fights that would very much prefer you stop existing. These aren’t just bigger run-and-gun arenas. Every pyramid is overflowing with traps, hazards, and environmental nonsense designed specifically to end your run in the most embarrassing way possible. And getting there? Not exactly a leisurely stroll. First, you'll need to take down the bosses lurking in the present-day biomes. One boss defeated, one artifact claimed, one new path revealed. Simple in theory. Less simple when something inhuman and ten times your size is trying to flatten you. Each pyramid brings its own flavor of suffering. Can you survive the blistering heat of the Fire Pyramid? Are you sure you want to know what’s hiding in the Shadow Pyramid? And perhaps the most important question, can you make it out of the Light Pyramid alive? That’s all we’re willing to tell you, despite this being the biggest part of the update. The rest? You’ll have to discover firsthand. Assuming of course, you survive long enough to see it.UI OverhaulEverything. And we mean everything. As far as the eye can see has been rebuilt visually and mechanically. Menus, progression, customization, the whole thing got dragged into the lab and came out significantly better looking. It's also fully reactive to controller input, which is objectively the superior way to play. Mouse and keyboard players, don't worry. We remembered you exist, too. Let's break it down. Permanent Progression with Randi The brand new permanent C.U.S.T.O.M. progression system is here. Unlock upgrades that perm...Read full article on Community Announcements (Kole)AnnouncementsOfficial

Ah yes. Balance. That magical word that means we changed things because some of you kept wiping before clearing the first biome. After observing player behavior we’ve rolled out a set of adjustments to make the game more readable, consistent, and slightly less like being shoved into a blender full of aliens. But only slightly.Enemy Population ChangesPreviously, the ecosystem of Chimera could best be described as every alien everywhere all at once. While that did create exciting moments, it also created situations where there was not enough time to learn enemy patterns and behaviors. So we’ve tightened up enemy distribution to make encounters more thematic and predictable.Certain enemies are now restricted to later biomes:Reptoids – Now appear only in Giza and beyondTall Aliens – Same deal, they’ve relocated to Giza and later areasLarge Drones – Also restricted to Giza+The idea is simple, earlier areas shouldn’t feel like the alien equivalent of the final exam. Progression should feel like escalation, not like you accidentally walked into the endgame while looking for snacks.Player Assistance ChangesYes, we helped you. Get used to it. We’ve made a few changes designed to improve survivability and clarity without turning the game into a guided tour.Improved UI for Buffs & AugmentsThe UI has been reworked to make buffs and augments easier to read.Changes include:Clearer iconsBetter visual distinctionMore readable status effectsNow you can actually glance at your buffs and craft your loadout faster.More Health PacksYou now start with 4 health packs instead of 1, and more can be picked up mid-run. You’ve got a bit more breathing room and margin for error. Use them wisely, or panic-spam them immediately when you see something with too many teeth. We’re not judging.Selectable Player ClassesYou can now choose specific classes with Randi, each with predictable equipment styles. This means consistent weapon loadouts, recognizable armor archetypes, more deliberate team roles.L...Read full article on Community Announcements (Kole)Patch NotesOfficial
