What is FNAF UCN?

Ultimate Custom Night (alternatively FNAF UCN) is a horror survival game which is a part of the scary universe of Five Nights at Freddy’s. The game, like other versions of FNAF, takes back its players to the infamous pizzeria, Freddy Fazbear Pizza, and again throws them into the role of a night security guard who is confined to a small office as vile animatronics attempt to get in.

Here is where you are allowed to make the challenge as difficult as possible, whenever compared with the earlier parts of the series. FNAF uses 50 animatronic characters, which players can select depending on seven games, which have an infinite number of gameplay opportunities as they are allowed to select their level of difficulty between 0 and 20.

The outcome is a terrifying horror adventure mixed with management of resources, tactics and immediate response as you battle to save your own life during the night.
