Barring a secret level, Sister Location does away with the survival aspect of previous games. While previous games have the player monitor and keep the animatronics from reaching the player, who remains at a stationary position, through five increasingly-difficult nights, the player instead has to fulfill a series of objectives, which differ depending on the night played. For example, Night 3 requires the player to cross a dark room while moving away from Funtime Foxy as well as dismantling Funtime Freddy by pushing a combination of buttons, while Night 4 has the player prevent springlocks from unscrewing while also preventing a horde of Minireenas from reaching the player. A secret level accessible on Night 5, however, is a near-recreation of the gameplay of Five Nights at Freddy's, which necessitates the player to conserve energy while fending off the animatronic Ennard from reaching the player's office by looking at the monitor and shutting electric doors, which consume power. As in Five Nights at Freddy's 2, every so often, when the player loses a mission and gets a game over, they are sent to play an 8-bit minigame involving Circus Baby, who has to deliver cupcakes to children; doing it causes an ice cream to appear, which can be delivered to a little girl who appears at the beginning of the level. Delivering the ice cream is necessary to be granted access to the secret level. Clearing all five nights unlocks a gallery, where the player can view the game's five animatronics, their making-of, the pizzeria's map and gain automatic access to Circus Baby's cupcake minigame. An achievement system exists in the form of three gold stars, obtained by unlocking both of the game's endings and delivering the ice cream in Circus Baby's minigame. The player character, named Mike, mistakenly referred to as Eggs Benedict,[3] is a new employee of the underground Circus Baby's Rentals and Entertainment, a sister company of Fazbear Entertainment featuring animatronic that are rented out to children's birthday parties; they were originally intended for use in a pizzeria called Circus Baby's Pizza World, but the pizzeria had been shut down shortly before it was supposed to open due to "gas leaks". Mike is instructed by HandUnit (an AI that helps the player throughout the game) to watch and turn on the animatronics by electrifying them so they may be used during the day. He is also guided by the voice of Circus Baby, a female clown animatronic and the star of Circus Baby's Pizza World, who gives instructions sometimes contradictory to those of HandUnit. Baby's instructions help Mike survive the nights from the hostile animatronics: the ballerina Ballora and her minions known as Minireenas; miniature animatronics known as Bidybabs; and the "Funtime" versions of Freddy Fazbear and Foxy the Pirate Fox. It is implied via monologues throughout the game, as well as the ending of the 8-bit-style minigame, that Baby houses the remains of company director Mr. Afton's daughter, who was previously killed by her in a freak accident. As the week passes, the animatronics are taken to the parts and service room one by one due to apparent malfunction. On the fourth night, Circus Baby reveals that she kidnapped the player, and hides him in a "spring lock" suit just outside the "scooping room", where the animatronics' bodies are forcibly removed by a machine Baby describes as "The Scooper" (designed in a way similar to an excavator), and watches as the machine tears Ballora's body apart. On the final night, two agents sent to fix the animatronics are found hanged. Mike is told by Baby to take her to the scooping room. From there, Mike can heed Baby's instruction and obtain the normal ending, or sidetrack to the hidden "private room" once completing Baby's minigame, where the player needs to clear a survival mission modeled after the first game for an alternative ending. In the normal ending, Baby reveals that she and the other animatronics have been attempting to escape the complex, but without a human guise, they are unable to. However, now that they are assembled with a sympathetic human, i.e. Mike, they have merged into a single animatronic called Ennard to take his body. The epilogue ends with Circus Baby deceiving Mike into entering the scooping room, then locking him in it and using the machine to disembowel him and take his body. The final scene of the game shows Ennard inspecting itself in the mirror while inhabiting Mike's body. In the alternate ending, Mike returns home to watch the season finale of the animated series The Immortal and the Restless (whose previous episodes are shown in-between the nights and whose plot lampoons the series). After the show ends, Ennard appears in the room and slowly advances towards Mike.
