Basic plot summary is that you get a new job at a place called Freddy Fazbear's Pizza, as a security guard. You have to work from 12 A.M. to 6 A.M. This would be no problem, but the animatronic characters turn evil during the night, and try to murder you. The game objective is to survive until morning comes. You can avoid the evil furry robots by closing the doors you have. But closing the metal doors consumes power, and you have a limited amount of power. If you run out of power, you only have 30 seconds left until you get caught. On top of shutting the doors, using the lights right outside your doorways, and checking the security cameras also consumes power. And like I said before, if you run out of power, you're screwed unless you have less than 30 seconds left until 6 A.M. An in-game night lasts approximately 10 minutes. This game is probably the scariest horror game I've ever played. It makes you really paranoid in every way. If you like horror games, you'll love 5 Nights at Freddy's.
