Five Nights at Freddy's launched in 2014 as a point and click horror game where a night guard monitors cameras and hallways for roaming animatronics. Its cramped office, flickering lights and off screen noises made ambient sound central to the fear, because danger was often heard before it was seen. Clips of its hallway atmosphere spread through YouTube lets plays, fan games and meme edits, and creators kept reusing the mood long after the first game. The sound remains popular for building dread without showing anything.
