Ultimate Custom Night is an action-packed game developed by Scott Cawthon. It is the ultimate mashup of all the Five Nights at Freddy's games, featuring 50 animatronic characters that you can choose from. The game offers endless customization options, allowing you to mix and match characters and set their difficulty level from 0-20.

As a player, you will be trapped in an office and will need to fend off the killer animatronics. You will have to manage two side doors, two vents, and two air hoses, which all lead directly into your office. In addition, you will have to use tools like the heater, A/C, global music box, power generator, and more to complete the ultimate challenges. You will also need to set up laser traps in the vents, collect Faz-Coins, purchase items from the prize counter, and keep a close eye on the Pirate Cove curtains.

The game also includes a challenge menu with sixteen themed challenges, voice acting from returning favorites as well as new arrivals, unlockable office skins, and cutscenes. Ultimate Custom Night is a must-play game for all Five Nights at Freddy's fans.
