Among Us is a social deduction game developed by InnerSloth and released in 2018, where players work together on a spaceship while hidden impostors try to sabotage them. At the start of each round, every player is secretly assigned as a crewmate or an impostor, and that reveal sets up the entire game. The game became a worldwide streaming hit in 2020, and its short sounds became shorthand for suspicion and surprise in videos far beyond the game itself.
