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 mini game. As of the 1 December 2016 update, clearing all nights also unlocks the non-canon Custom Night mode, which is set in a modified version of the Night 5 secret room. The player can choose from several modes and difficulty settings, facing new animatronics, and must conserve both power and oxygen supplies in order to survive.
