Surviving Ultimate Custom Night with multiple animatronics active requires a system. Random checking and panic responses will drain your power and get you killed. Here is how to build a routine that works.
Establish a camera check cycle. Visit the most critical camera positions in a fixed order every 10 to 15 seconds. This ensures no animatronic moves undetected while minimizing the power cost of camera usage. Skipping checks to save power is tempting but almost always leads to a surprise attack.
Prioritize door management in Ultimate Custom Night. Doors are your most reliable defense but also your biggest power drain. Close them only when you have confirmed a threat is approaching, and open them the moment the threat retreats. Leaving doors closed as a precaution burns power you will need later.
Learn which animatronics are audio-based versus visual-based. Audio threats require you to listen for specific sounds and respond with the correct action. Visual threats need camera monitoring. Mixing up the response types wastes time and power on ineffective countermeasures.
The final hour is always the hardest. Power is low, multiple animatronics are at peak aggression, and your margin for error is razor-thin. Save at least 15 percent power for the 5 AM to 6 AM stretch. If you enter that hour with less, your chances of surviving drop dramatically.
Start with low difficulty settings and increase gradually. Ultimate Custom Night is designed to be mastered incrementally. Each difficulty bump teaches you one more animatronic pattern, and that knowledge compounds until you can handle configurations that seemed impossible during your first attempts.
When you fail, note which animatronic got you and why. Was it a missed camera check? A door left open too long? A sound cue you ignored? Each death in Ultimate Custom Night teaches something specific, and players who learn from failures improve faster than those who just restart and hope for better luck.
