Among Us, developed by InnerSloth and released in 2018, lets Impostors sabotage doors to trap Crewmates in a room and slow their tasks. The door sabotage alert became widely recognised when the game exploded in popularity in 2020 through streamers and short-form videos, where its tense beeps were reused as shorthand for being cornered or caught. It remains popular because the sound is instantly recognisable to players and works even without any gameplay footage.
