Survival horror reaches its peak when you are forced to manage dozens of relentless animatronics simultaneously. UCN - Ultimate Custom Night turns the classic fnaf formula into a high-stakes strategic challenge where you dictate the difficulty. You start by selecting from fifty iconic characters, assigning them individual AI levels to create your own personalized nightmare scenario. Gameplay revolves around multitasking between camera feeds, power management, and locking heavy doors to stop intruders from breaching your office. Each active character increases the potential point total, pushing you to test your reflexes against the most aggressive configurations imaginable. Beyond the standard survival loop, you can customize your office aesthetic or utilize starting bonuses to gain a narrow edge against the machines. The infamous 50/20 mode remains the ultimate gauntlet for masters of the five nights at freddy series who want to prove their skills. Experience all the terror directly in your web browser for free with no downloads required.
In the main menu, you can activate animatronics that will be active during the night:
— Choose any animatronics you like
— Select a pre-made challenge and complete it!
You can also choose the office where you'll spend the night and a bonus to help you at the start of the game.
During gameplay, you need to monitor cameras, both main and additional ones, and keep an eye on the doors to close them at the right time.
Your score depends on the number of active animatronics and their assigned AI level.
The ultimate test is the "50/20" mode — set all animatronics to level 20 and try to survive the night!
