Five Nights at Freddy's 4, released in 2015, is the fourth entry in Scott Cawthon's survival horror series and moves the action into a child's bedroom, where the player must listen at two doors and a closet for approaching nightmare animatronics. Closing a door is a core defensive move, so its sharp slam became instantly recognisable to players who learned to react to sound cues alone. The clip later spread beyond gameplay videos into horror edits and short-form videos, where it still works as a quick signal of danger, hiding and a scene shutting down.
