Clearing all five nights unlocks a gallery of extra features: pictures and blueprints of the game's animatronics, their making-of, a map of the facility, and automatic access to Circus Baby's cupcake minigame. Here, the player remains in a security office and must prevent a hybrid animatronic called "Ennard" from entering it by watching surveillance cameras and closing electric doors, all of which consume a limited power supply. Completing this minigame grants access to a secret level during Night 5, a near-recreation of the gameplay in the original Five Nights at Freddy's. As in Five Nights at Freddy's 2, when a game ends, the player may be given a chance to play an 8-bit minigame, in which Circus Baby must give cupcakes to children and then bring an ice cream cone to a little girl. For example, Night 2 requires the player to sneak across Ballora Gallery and reset a group of circuit breakers, while for Night 4, the player is placed inside a springlock suit and must keep its spring locks wound up while shaking off the animatronic dolls (Minireenas) that climb onto it.
Instead of remaining in one place and preventing the animatronic antagonists from attacking, the player must move from room to room in order to fulfill a series of objectives that change during each of the five nights.
The bulk of the gameplay in Five Nights at Freddy's: Sister Location does away with the survival aspect of previous games.
