Five Nights at Freddy's 2, released in 2014 as the sequel to the original horror game, expanded the office gameplay with a vent system that animatronics could use to reach the player. The vent audio became a recognisable cue for fans who watched playthroughs and streams, where hearing it meant checking the vent lights immediately. It has since been reused in fan edits, jumpscare compilations and horror videos because it carries that same warning meaning without needing any visuals, keeping the game's tension alive years after release.
