Among Us is a multiplayer game for four to fifteen players, although recommended for at least five.[11] Up to three players are randomly[12] and secretly chosen to be the Impostor(s) each round. As of 2021, a round can take place on one of four maps: a spaceship called "The Skeld"; a headquarters building called "MIRA HQ"; a planet base called "Polus";[13] or an airship based on Innersloth's Henry Stickmin series called "The Airship".[14][15] The Impostor(s) win(s) one of two ways: either by killing most of the crew (to the point that they're equal in number) or by sabotaging a critical system on the map (provided the Crewmates don't resolve it in time). The Crewmates likewise can win one of two ways: either by completing all tasks or by identifying and ejecting all Impostors.[13] Games can also end by players quitting the match if doing so fulfills any win condition (if a Crewmate quits the game, their tasks are automatically considered completed).[16][17][18] Among Us, Impostor, game, multiplayer, crewmates, impostors, spaceship, maps, tasks, sabotage, strategy, win conditions, 2D, adventure, alien, arcade, webgl, mobile game, online game, social deduction, deception, suspense, voting, kill, escape, innersloth
