Nightmare's full body view is unlocked by completing Nightmare mode. The first six nightmare animatronics are unlocked for a full view. However, unlike in the third game, the player can view everything except the minigames without having to do certain tasks. The menu can only be unlocked if the player has completed Night 5. However, phantom animatronics, specifically Phantom Freddy, can still jumpscare the player. This also means that the player can stare at him for a long time when he is outside the window or door at a very early time, and Springtrap will still not be able to get the player (unless they open the Maintenance Panel or Monitor). No Errors - When this cheat is checked, none of the systems will produce any errors and fail, and the player will not have to use the Maintenance Panel at any time, making the night focused on finding Springtrap and getting him as far away as possible.As of version 1.03, completing Nightmare Mode with only this cheat enabled will also reward the player with a fourth star on the main menu. With this cheat and Nightmare combined, the player is theoretically simulating the highest Custom Night difficulty in Five Nights at Freddy's 3.
This option is very similar to Cheat Mode from the Android version of Five Nights at Freddy's. Whenever the player experiences the "Multiple Springtraps" hallucination, the radar will point out the real one. If Springtrap moves, this dot moves with him to the next CAM. A white dot with a red outline will be marked on the CAM where Springtrap is located.
Each hour is about 29 seconds, now making a night about 2 minutes and 53 seconds (rather than the usual 5 minutes and 48 seconds), the shortest night length in the series, even shorter than the first game's mobile version (tested on version 1.03). Fast Nights - When this option is checked, the nights would go much faster and, by extension, much easier to complete.This is unlocked with when the player gets all three stars (since the player can get the Good Ending before beating Nightmare mode). Because of this, it can be considered a replacement of the traditional Custom Night. The last option in the Extra menu, this option allows the player to tweak their gameplay by enabling certain cheats to make the game easier or harder.
