Among Us takes place on a space ship in outer space. There are two teams: the Impostors and the Crewmates. There can be a total of 10 players in an online game, with up to three impostors. The Impostors’ objective is to eliminate all crew-mates using either aggressive, defensive, or passive tactics before the crew-mates complete all of their tasks or discover their true identity. The crew-mates’ objective is to complete all of their tasks while figuring out who the Impostor is.

Among Us is a multiplayer game, supporting 4–10 players. 1–3 of these players are randomly selected each game to be Impostors, while the rest are Crewmates. The game can take place on one of three maps: a spaceship (The Skeld), a headquarters building (Mira HQ), or a planet base (Polus).
