Gameplay

Five Nights at Freddy's is a horror game that tasks you with surviving five nights at a Freddy Fazbear's Pizza restaurant. You play as a security guard who must keep an eye on the restaurant's four animatronic mascots, Freddy, Bonnie, Chica, and Foxy, to make sure they don't sneak into the office and end your life. 
The mascots move around the restaurant at night, and if they catch you off guard, they'll jumpscare you and end the game. To keep an eye on them, you use a series of security cameras placed around the restaurant. You can also close the doors to the office to keep them out. If you survive five nights, you unlock an extra night where you play as Freddy Fazbear.
