Join forces in Killing Things With Your Friends, a 2026 co-op survival game from Flightless where you and your friends work together to dismantle mutant hordes with creative weapon hacks.
About this game
Killing Things With Your Friends is a co-op meat-grinder built around creative dismemberment. Tear off mutant limbs and use their abilities to survive the gauntlet of deadly lab experiments.
Work together, impress the researchers, and you might leave rich.
Fail and you might just become the next mutant experiment.
WELCOME TO EXOGEN LABS
Gather your team, sign the waiver you definitely read the fine print for, and enter our test chambers filled with puzzles, hazards, and semi-successful mutant ‘Things’.
Complete all the trials and escape before the timer expires, or you might just expire with it!
BODY PARTS ARE WEAPONS AND TOOLS
Rip them off, throw them away, and pick up something fresher from the bloodied floor.
Improvise your arsenal from whatever still twitches nearby.
Combine different limbs to gain the upper hand in fast-paced combat, and when you run low, harvest some more from your foes… or friends.
NO TRIAL IS EVER THE SAME
Trials are designed to test communication and coordination.
Survival requires teamwork! Layouts will shift, Test Subjects get stronger, and puzzles are ever-evolving.
You’ll share weapons, tactics, and mutant body parts, with dozens of unique challenge rooms to complete in our procedurally generated trials.
Sometimes lending a hand might cost you an arm (and a leg).
SURVIVE, ADAPT AND EARN GOLD
After all, why else would you sign the waiver?
Complete small challenges to unlock upgrades and spend your gold on new limbs, buffs, cosmetics, and more!
Advance toward becoming the perfect specimen.
KILLING THINGS IS BETTER WITH FRIENDS
Invite up to three other Test Subjects to survive the chaos of Exogen’s labs in public or private lobbies, or face the mutants alone if you seek a mindless slaughter.
United you stand.
Divided… you still stand, just on fewer legs.
FEATURES:
🥳 1–4 player online co-op
🧩 Vast array of unique challenge rooms
🩸 Dismember your enemies & each other
🦵 Numerous mutant weapons
🎙️ Proximity voice chat
🏗️ Procedurally generated trials
🤡 Character cosmetics
🎶 Original soundtrack from Jeremy Cullen
