Five Nights at Freddy's: Sister Location is a demo for the original FNAF game. It includes Night 1 & half of 2. You are hired to work as a late night technician. And your mission is to watch and motivate animatronics by electric shocking. Besides, you also have another objective that is to survive as long as possible because you can be attacked by anything in the Circus Baby’s Pizza World. Dissimilar to other Fnaf games, you can crawl through air vents to head to rooms. Remember to keep an eye on Ballora, Funtime foxy, and more. Good luck!
