Kid, Geek, Gamer, Director, Needs a life.
Easily the scariest running next to fnaf 4. The game's atmosphere and tone gives it the spooky factor. Add that to the animatronics trying to kill you with some backstory and you've got a hit game. It has some flaws and the jumpscares don't get you that much when you get to night 5 or 6, but it's still a great game.
