FNAF 7 is more than a game. The main character is a guy who has to spend five nights with Freddy and the other animatronics, working the night shift as a guard in a pizzeria.

Animatronics that entertain children during the day turn into something else after midnight. Save energy and watch the cameras. Close the doors quickly when you see Freddy and his gang. Your task is to stay alive for five nights at work. A useful hint is the battery indicator on the screen, which tells you how much room for error you have left.
