COS-MOS

COS-MOS is a cooperative party game for 2-4 players where you navigate chaotic space challenges: repair your ship, solve puzzles, overcome traps, and rescue each other in a world of hilarious and unpredictable ragdoll physics.

You and your crew wake up aboard a barely functioning spaceship drifting through space. Systems are failing, alarms are blaring, and something keeps hitting the hull from the outside.There’s no time to ask questions — only to act.You must work together to keep the ship alive: restore power, fix the oxygen system, and venture into open space to restart the engine. Every task requires coordination, timing, and a bit of luck… because nothing ever goes exactly as planned.With physics constantly working against you, even the simplest actions can spiral into chaos. Tools slip, objects fall, and your own teammates might become the biggest obstacle.Each step forward brings you closer to your destination — if the ship doesn’t fall apart first.<h2 class="bb_tag" >Key Features</h2>Co-op chaos Play with 2–4 players and try to survive together… or accidentally sabotage each other.Fully physics-based gameplay Everything is interactive.
