About this game
COS-MOS is a 3D co-op game for 2–4 players, where you must overcome a series of crazy challenges in space, on the Moon, on an alien planet, and in other unusual locations. The game combines adventure, puzzles, physics-based interaction, and chaotic team gameplay, where success depends not only on coordination but also on the ability to handle unexpected situations.
Each level introduces new mechanics and objectives: using both hands to carry objects, inserting parts into machines, repairing systems, operating buttons and levers, driving vehicles, moving heavy objects together, and overcoming areas with ice, low gravity, and the vacuum of space. This keeps the gameplay varied and prevents it from feeling repetitive.
DANCE!
FIGHT!
SHOOT ALIENS!
RIDE BOATS!
AN SNOOP DOG REFERENCE!
A SPACEX REFERENCE!
And much more awaits you in COS-MOS!
