There is now a global music box, which is more efficient but drains a lot of power, and different musical selections.

Used to deal with a few specific animatronics, those being the Marionette, Chica and Lefty.Having the doors closed for a long period of time wastes a lot of power. One of the main ways to prevent animatronics from entering the office.Some timing is needed in order to be successful. Used to deal with some animatronics strategically, by flashing it at them.The access to it can be conditioned by a few animatronics. Also used to operate most of the other mechanics in the game. Used to check all the cameras, vents and ducts.Some mechanics are returning from other games, while others are exclusive to UCN. UCN features a wide range of different mechanics all of which have to be mastered in order to beat 50/20 mode. Lastly, there's a checkbox which toggles characters' decriptions on and off.

There are also other buttons, such as the challenges, which allows you to select a pre-made combination of animatronics and their difficulties, the power-ups, which give you a boost in the following night, and the offices, giving you four different offices to play in, the first one being unlocked from the start and the other three unlocked by different high-score values. You can, of course, manually set the difficulty of any animatronic, manually, to any number between 0 (not active) to 20 (max.

There are buttons on the right side of the screen which allow you to set the difficulty of all animatronics to 0, 5, 10 or 20. There are 50 slots in total, each one with a different selectable animatronic. The game starts and the player is immediately greeted with this menu.
