Mr Krabs has opened a brand new Krusty Krab in the city, staffed completely by animatronic versions of his old employees (because it was cheaper than paying their salarys). You are hired as the night watchman at this new restraunt, however strange things begin to happen as the lights go out, and you find yourself in a greater danger than you had expected...

Mr. Krabs had decided to open up a brand new Krusty Krab in the city. He builds animatronic versions of the older employees (since it was cheaper then paying their salaries), and hires two humans to keep charge of the restaurant, the player, and the Phone Guy. When it turns night, the player begins their night shift and these animatronics go on a hunting spree for blood. Your blood.
