Five Nights at Freddy's (FNaF) is an American media franchise
created by Scott Cawthon.
The main series consists of nine survival horror video games
taking place in locations connected to a fictional family pizza restaurant franchise
named "Freddy Fazbear’s Pizza", after its mascot, the animatronic bear Freddy Fazbear.
In most games, the player assumes the role of a night-time employee,
who must utilize tools such as security cameras, lights, doors, and vents
to defend themselves against hostile animatronic characters that inhabit the locations.
