Among Us was released by Innersloth in 2018 and surged in popularity in 2020 through Twitch and YouTube, making its sabotage alerts instantly recognisable. The oxygen crisis occurs when an impostor triggers the O2 sabotage, forcing crewmates to enter codes at two locations before time expires or the impostors win. Clips of close calls helped turn the alarm into a standalone meme sound, similar to other game alerts like the danger alarm sound effect meme. It remains popular because the beeping alone communicates a race against time.
