Enter the Gungeon was released in 2016 by Dodge Roll as a bullet hell roguelike about exploring a gun themed dungeon to find a gun that can kill the past. Its death sound became a shorthand outside the game because runs are long, deaths are frequent, and the cue is instantly recognisable to players. Like the ROBLOX oof, it has moved into edits and streams as a universal game over marker, used whenever a character or player fails in a way that feels abrupt and final.
