Five Nights at Freddy's 4 was released in 2015 by Scott Cawthon and shifted the series to a child's bedroom, where sound became the main defense. At each door the player must listen carefully, because a faint breath means an animatronic is close enough to require closing the door immediately. Getting it wrong leads to a jumpscare. That listen or die mechanic made the breathing cue iconic among fans, and the isolated clip later spread through soundboards and fan videos as a shorthand for hidden danger nearby.
