Five Nights at Freddy's: Security Breach is undoubtedly the biggest game in the FNaF series to date (if the initial 80 GB filesize on PC didn't prove it enough). Spanning across the Mega Pizzaplex, a seven-story building, this game breaks the traditional 'sit on your chair and keep the animatronics away' formula of the previous games and instead goes for a free-roam mission-based structure, a first for the series.

Despite being delayed two times before release, there is still tons of content left over in the files. The sheer amount of removed lines that are vital to the story, comments from the developers, and unused functional content suggests that a lot of stuff was dummied out in order to finish the game on time.

To do:
A few things:
  • Document the debug menu for the golf section.
  • Keep an eye on maz0ntwt, as they're documenting a ton of unused dialogue and such.
  • There is a very unfinished 'Survival' mode in the Extras menu, allowing you to customize animatronic encounters, which should be documented.
  • Document LightTest's Pizzaplex, as it contains many differences, including unused hallways, unused textures, and more.
  • Add Plushbaby's model and animations (there may also be leftover voicelines).
  • Document Vanny's AI in Survival Mode.
  • Document the changes made in the February patch.

Unused Code

Unused Burntrap AI Properties

To do:
There are more AI parameters that have yet to be written down here

Despite never chasing the player in-game, Burntrap has fully configured AI parameters like the rest of the animatronics. This may mean that earlier on in the game's development, you may have actually been chased down by Burntrap, but in the final game this never happens.

There is a folder in the game's content directory called TEST_ProceduralWalls that contains many textures, meshes, and a 9211-line-long blueprint file called BP_SplineWall.uasset. It is unknown what this would have been used for.

Unused Text

This section will only detail text that wouldn't have been shown via subtitles. For unused subtitles, see the Unused Dialogue sub-page.

Hour Length

Used in the Survival Mode menu.

WARNING - Time does not stop when looking at the Faz watch.

This line of text makes it seem like at one point in development, Gregory bringing up the watch would not pause the game, allowing the Animatronics to still jumpscare him when it is up.

Cameras, messages, and more can be accessed through the watch.

A basic text string that teaches the player about what they can use the Fazwatch for.


These strings of text are used in the unused Survival mode settings page, as seen in the unused Extras menu.

Unused Models

Chica's Guitar

An earlier version of Chica's guitar is present within the files, consisting of different textures and a slightly different model. Interestingly, this model is used by the Chica hologram in the final game, though the regular version is never used.

Frozen Endo

Fnafsb frozenendomodel.jpg

An unused endoskeleton enemy that, aside from a model, only has scrapped mission text mentioning it. In the final game, its head and some parts of its body can be found in the first office in the game, but the rest of the model goes unused. The related unused dialogue suggests that this would've appeared in a scrapped boiler room area.

Magician Bot


A model for a magician S.T.A.F.F. Bot. A broken-down version can be seen in the final game after exiting the sewers, but this fixed version is never used at all.

Unused Objects


The elevator found in the main area has buttons that are unable to be pressed due to the doors never opening. If the player were to enter the elevator via hacks, however, the buttons can be pressed, making the elevator doors close and loading the player into a separate area of the map. This elevator was once seen in a pre-release trailer, but it is never used in game through legitimate means.

Glass Ball

An unused distraction that resembles a glass ball. When summoned in game, it quickly falls to the ground and shatters, signaling nearby animatronics.

Development Text

To do:
There's very likely a lot more of these.

Development Text in Maps

In the raw asset files for the maps of the game, several strings of normally-unseen debug text can be found, some of which may refer to unused content. It should also be noted that these are all seen in "old" versions of areas that appear to have had an updated map made (i.e. MAP_Laundry_Room_LightsOn vs. MAP_Laundry_Room_NEW_LightsOn).

Fnafsb devtextdoor.png

In MAP_Laundry_Room_LightsOn, the text 'Requires Staff Bot' can be seen in front of a door. The closest thing to using a Staff Bot in the game is when the player temporarily controls the chef Staff Bot in order to lure out Chica, but that happens nowhere near where some of these doors are located. It is also possible that this was just a note left in by a developer leaving a reminder that a Staff Bot still needs to be added here, as in the final version of this area a Staff Bot is seen behind this door.

Fnafsb devtextgate.png

Also found in MAP_Laundry_Room_LightsOn, above a fence in one of the rooms, is some text that says 'FenceGate(Locked)', despite no such gate existing in this room. This suggests that a fence gate (probably requiring Monty's Claws or Chica's Voicebox) was once planned to be inserted here.

Fnafsb devtextelectrical.png

Found out-of-bounds in MAP_Loading_Dock_Hallway_LightsOn is text that states 'ElectricalBox'.

Internal Development Text

Of course, there is also some development text located in the internal files of the game. A few of these were added in the 1.05 patch of the game, and include some interesting stuff, such as references to cut locations, as well as some colorful language in a few areas..

Changing visual settings requres you to restart the game.
Cheese Station
Crust Station
Delete the shit out of this file right about now.
Freezer room. Chef boyardee can food is all stored here. Most of the food is stored in boxes. (Probably should have used more boxes than cans for the whitebox)

Internal Name

The game's .exe file is referred to as 'fnaf9.exe'. Additionally, several internal files refer to the game as 'Quarters'.

Revisional Differences

12/23/21 Patch

This patch released on December 23rd, 2021, over a week after release, fixing various bugs:

  • Fixed an issue relating to being unable to recharge Freddy in the Parts & Service room.
  • Fixed an issue with Freddy appearing too early after exiting the sewers.
  • Allowed players to interact with arcades that were previously inaccessible.
  • Fixed an issue regarding mission objectives repeating themselves and not properly updating.
  • Moved two Retro CDs due to issues with Freddy being intermittently accessible. They've been pulled out of El Chips and Prize Counter and placed elsewhere.
  • Prevented some Security Badges being obtainable multiple times.
