Fallout 76 is Bethesda's online multiplayer entry in the Fallout series, released in 2018, where launching a nuclear weapon is a major endgame event. When a player targets an area, other players in the zone hear this imminent strike warning, giving them a short time to escape before the blast. Clips of the alert spread among Fallout players and gaming editors because the sirens instantly signal something huge is coming, even outside the game. It remains popular as a shorthand for an incoming disaster in memes, montages and reaction videos.
