The game allows the player to choose from 50 characters from all six main Five Nights at Freddy's games and FNaF World, and set their difficulty levels for the night from a minimum of "0" to a maximum of "20". The full roster includes Five Nights at Freddy's characters Freddy Fazbear, Bonnie, Chica, and Foxy, Five Nights at Freddy's 2 characters Toy Freddy, Toy Bonnie, Toy Chica, Mangle, BB, JJ (a female version of BB that previously appeared as a hallucination), Withered Chica, Withered Bonnie, the Puppet, and Golden Freddy, Five Nights at Freddy's 3 characters Springtrap, Phantom Mangle, Phantom Freddy, and Phantom BB, Five Nights at Freddy's 4 characters Nightmare Freddy, Nightmare Bonnie, Nightmare Fredbear, and Nightmare, plus Jack-O-Chica, Nightmare Mangle, Nightmarionne, and Nightmare BB from the game's Halloween Edition, Old Man Consequences from FNaF World, Five Nights at Freddy's: Sister Location characters Circus Baby, Ballora, Funtime Foxy, and Ennard, and Freddy Fazbear's Pizzeria Simulator characters Trash and the Gang, Helpy, the Mediocre Melodies (Happy Frog, Mr. Hippo, Pigpatch, Nedd Bear, and Orville Elephant), the Rockstars (Rockstar Freddy, Rockstar Bonnie, Rockstar Chica, and Rockstar Foxy), the Posh Pizzeria (Music Man, El Chip, and Funtime Chica), Molten Freddy, Scrap Baby, William Afton / Scraptrap, and Lefty, with the last character being the Phone Guy. During the night, the player must keep track of several mechanics, such as doors, ventilation systems, and air duct systems to avoid being attacked by the animatronics. The player can earn "Faz-Coins" to buy power-ups and deflect animatronics, and a "Death Coin" to eliminate a certain animatronic from the current night. The player is also able to select the office setting, choose power-ups that may help them during the night, and select 16 challenges available to them. The objective is to survive from 12 AM to 6 AM, with each hour in-game lasting 45 seconds. In the final release, 59 characters from the franchise were included, with some appearing without the player's choice. Of these extra nine, Dee Dee from FNaF World, has the ability to randomly spawn and summon either a character that isn't currently active or one of six that are unavailable to the player, with a new form of her named XOR being able to summon all of the extra six. These six include RWQFSFASXC / Shadow Bonnie from Five Nights at Freddy's 2, Plushtrap and Nightmare Chica from Five Nights at Freddy's 4, Minireena and Lolbit from Five Nights at Freddy's: Sister Location, and Bonnet from that same game's Custom Night. An easter egg involving using the Death Coin on Golden Freddy when he's the only active character on a night and set to 1 triggers a jumpscare from Fredbear, the earlier incarnation of Golden Freddy who had previously only appeared in minigames.
