Five Nights at Freddy's 4 is the fourth game in the series and the final chapter of the series' overarching story (until it wasn't). Instead of taking place in a pizzeria like the other games, FNAF 4 takes place in a regular suburban house, where a young child has to fend off nightmarish versions of the animatronics using only a flashlight.

Unused Graphics

[Frame 2] titlescreen

Demo Leftover

A leftover piece of text from the game's demo version of the main menu can be found in the files of the full version.

Star Animation

An animation, intended for the unlockable stars on the main menu. Curiously, these are intended as separate animation sequences, possibly meaning the regular stars could be converted into these at one point in development in some way. Despite this, no code is associated with them.

The end of demo screen can also be found in the full version's files as well.

Unused Code

Original 20/20/20/20 Mode Ending

After beating 20/20/20/20 mode, an ending was supposed to occur similar to Nightmare mode's ending, except the player could actually open the lockbox's locks (which would move downward and fade away upon doing so); however, the box still cannot open. While it IS technically used, this is completely inaccessible without modding due to 20/20/20/20 mode always sending the player to the title screen upon completion.

* User clicks with left button on Active 2
+ Alterable Value A of Active 2 = 0

[Frame 13] Cutscenes

Nose Honk

A hitbox internally named honk can be found out of bounds in the cutscenes. It has functioning code, and behaves identically to the Freddy Plushie nose-honking easter egg on the bed in the main levels; clicking on it with the left button makes a honking noise. This leads to the possibility that you could originally honk the Fredbear plushie's nose. It is possible that this was scrapped due to the cutscenes always hiding the mouse cursor by default, thus making honking the nose impossible.

Event 198

* User clicks with left button on honk
	 Sound : Play sample PartyFavorraspyPart_AC01__3 on channel #10

Unused Text

[Frame 7] intro to plushtrap

Unused Strings

Two unused pieces of text for Fun With Plushtrap's tutorial screen can be found out of bounds, and use a completely different font from the final game. They also reveal that beating the minigame would originally only skip one hour on your next night instead of two. Both unused strings read as follows:

Fun with Plushtrap

Hold Ctrl to use Flashlight. Use flashlight to stop Plushtrap on the "X" to skip 1 hour on your next night.

[Frame 11] extras

Pre-Completion Nightmare

Before unlocking Nightmare in the extras menu, his animatronic name display text is supposed to read the following string, however it is normally invisible and cannot be viewed without modding.

[Frame 13] Cutscenes

Chapter Text and Counter

Some unused text that says "Chapter". It was intended to be designed for the minigames, however it is placed out of bounds and thus goes unused. Interestingly, a counter that was intended to be used alongside this text actually has code associated with it, but it too is placed out of bounds and its code does not work properly.

Debugging Material

[Frame 4] level

Test 2

A counter can be found off-screen at all times referred to internally as test 2. This counter always sets itself to Nightmare Fredbear's closet or bed kill timer. A game over is achieved if this value is greater or equal to 10.

(Source: Original TCRF research)

Test 3

Another off-screen counter can be found in the files named test 3. This counter shows an alterable value stored inside the map radar icon for the closet. This value will set itself to 1 if Bonnie or Chica are at the far ends of the hallways and the player shuts the door, causing them to go to your doorway immediately. This mechanic is presumably a punishment system for the player closing the door when they are not in danger yet.

[Frame 8] plushtrap game

Test

A counter can be found off-screen named test. This counter is always set to an alterable value stored in the main background object. When the player is not using the light, the value is set to 0, but if the flashlight is used, this value is set to 1. If any of Plushtrap's animations (excluding when he lands on the X) play, this value is set to 3 until the animation sequence ends. Curiously, this value is set to an insanely large value of 98 when Plushtrap successfully lands on the X.

Miscellaneous

Oddities

Nightmare Jumpscare

Prior to v1.1, Nightmare's killscreen would send you to the warning screen. However, as of v1.1, this was changed to jump to a deleted frame (which still jumps to the warning screen due to the way the engine handles deleted or missing frames). What this scene would have been is completely unknown.

Event 2 (Pre-v1.1)

* Timer equals 05''-00
	Sound : Stop any sample
	storyboard controls : Jump to frame "Frame 17" (1)

Event 2 (v1.1)

* Timer equals 05''-00
	Sound : Stop any sample
	storyboard controls : Jump to frame (deleted frame, please replace action)
