FNaF is Five Nights at Freddy's, a survival Horror game series. The player character has the role of a security guard on a night watch, at a family restaurant called Freddy Fazbear's Pizzeria. His job is to keep an eye on the animatronic characters who will roam the venue at night. The problem with this is, if they encounter a person at night, they will assume they are an animatronic 'skeleton' without a suit, and force the person into a suit. This will be a fatal experience due to the nature of the suits.
