COS-MOS Demo

About this game

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.

Key Features

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. You don’t press buttons — you physically grab, carry, and manipulate objects.

Unpredictable situations
Ragdoll movement and real physics turn every task into a challenge — and often into something much worse.

Minimal UI, maximum immersion
All actions happen directly in the world through physical interaction, without relying on traditional interfaces.

Your first mission
In this demo, you’ll complete training and attempt to repair your ship under pressure in the first level.
