Among Us was released in 2018 by American studio Innersloth and exploded in popularity in 2020 through streams and social videos. On maps like The Skeld, impostors can sabotage the reactor or oxygen supply, triggering a countdown that forces crewmates to rush to fix it or lose the game. Clips of that alarm later spread beyond gameplay into meme edits and soundboards as a universal signal for disaster. Its link to high pressure rounds and impostor chaos keeps it recognisable to players and non players alike.
