Five Nights at Freddy’s: Ultimate Custom Night (UCN) is a point-and-click survival horror game developed by Scott Cawthon. Released on June 27, 2018, it serves as the "Ultimate" installment in the franchise, acting as a standalone expansion of the "Custom Night" mode featured in previous titles. While technically a spin-off, UCN is considered canon-adjacent and provides crucial narrative closure to the lore, specifically regarding the fate of William Afton. Its "exclusive" nature lies in its massive scale, offering the largest roster of antagonists and the highest level of customization in the series' history.
