Among Us is a multiplayer game designed for 4 to 15 players, with 5 or more recommended for the best experience. Each round, up to 3 players are secretly selected as Impostors. The game features four maps: The Skeld (a spaceship), MIRA HQ (a headquarters), Polus (a planet base), and The Airship (inspired by the Henry Stickmin series).

Impostors win by either eliminating enough Crewmates to equal their numbers or sabotaging vital systems without repairs. Crewmates can win by completing all assigned tasks or ejecting all Impostors. Games may also end if players leave in a way that triggers a win condition, such as tasks being auto-completed if a Crewmate quits.
