|This page sucks.|
If you could make it suck less, that would be awesome.
Specifically: This is a really good game and deserves better than this horribly-formatted todo-filled piece of trash.
Portal 2 doesn't have any cake, but there's plenty of space to move around and find unused things in. The game's ending leaves several questions unanswered, although one was eventually answered as a DLC in The Elder Scrolls V: Skyrim.
A whole bunch of stuff.

| Unused Lines|
Cave Johnson has a lot of unused lines.
More unused GLaDOS taunts, referencing Chell by name, and Portal leftovers. Also, upload the dialogue files separately, not merged into one.
|Unused prerecorded messages from chapter 1 which are replaced by Announcer's prerecorded messages.|
|Unused speech from the scene where GLaDOS is reactivated.|
|These are thought to be from an unfinished scene in which you'd hear a recording of Caroline getting forcibly turned into an AI.|
|Extended unused speech of Wheatley talking about nanobots. The dialogue is shortened in the final.|
|An alternate version of meeting potato-ized GLaDOS. In one version of the script, she continued being a snarky jerk at you even while impaled on your Portal Gun. This got on testers' nerves very very quickly.|
|From an earlier version of the co-op plot, in which GLaDOS sent Atlas and P-Body out to find "artifacts" of the long-dead Aperture workers (coffee cups and such) to make them more human. Here, they've found a certain newspaper comic strip, presumably Garfield.|
|This was heard when the co-op demo was completed when the game was being played at PAX.|
|A snippet of dialogue from Dr. Kleiner in Half-Life 2. It's listed as error.wav in the game files, and it plays when the game fails to load a required file, something that doesn't really happen unless the game has been tampered with or improperly installed. In the PS3 port, this sound is played occasionally when the buttons next to the vitrified test chamber doors are pressed, though it is currently unknown why this is, or if it occurs in other versions of the game.|
|5 seconds of pink noise. Likely used for testing.|
|Entering adhesion gel.|
|Exiting adhesion gel.|
|Unused paint idle SFX.|
|Unused paint trickling sound effect.|
|Unused line for when the player is spotted by a Turret.|
|Unused line for when a Turret is searching for the player.|
|Unused line for when a Turret is shooting at the player.|
|Unused lines for when the player knocks down a Turret.|
|Unused lines for when the player picks up a Turret.|
|A beep sound that was used as a placeholder for the real music cues.|
|This is supposed to play after jumping a second time trying to say "apple", but another track is used instead.|
|A fragment of "Self Esteem Fund" from the first Portal, followed by a spark sound effect.|
|Workshop maps made in the Perpetual Testing Initiative will randomly choose between five music tracks. This one is listed along with them, but is never chosen.|
A purple gel which, when used with portals, would allow the player to walk on the walls and ceiling of test chambers. While this may sound neat, it proved to be disorienting and cause motion sickness among playtesters. You also could not use portals while the effects of adhesion gel were taking place (while you were walking on walls/the ceiling). This led to it being cut from the game (and eventually replaced by reflection gel), although the textures remain. Because of this, several community map-makers have tried (with varying success) to implement it in their maps. A video of it (albeit after the effects were removed) can be found here.
An unused gel type that reflects lasers. Added in the PeTI update, and can be added into a map by setting the Paint Type keyvalue to 1 (Stick). It replaces the Adhesion Gel that was dummied out before the PeTI update was released, although it still contains all of the Adhesion Gel effects that made it into the final game.
The gel uses the textures for conversion gel. Due to this and the fact that it is still usable (to some effect), it has been used by some community map-makers in their maps, with only minor problems with animation and textures. A video of the gel can be found here.
Two placeholder graphics found exclusively in the PS3 version of the game.
References to a camera weapon can be found scattered throughout the game files. One of these takes the form of a full unused texture for a camera model, likely a world model, simply named "camera.vtf". In addition, there are references to an HUD icon for this camera at "hud_icon_camera.vtf", along with several other similarly themed cut HUD icons, presumably remnants of F-Stop.
Investigate this. There may be more chicken references left in the code.
The most bizarre entity by far is a chicken. It has a script named "npc_sounds_chicken.txt" with five clucking sounds, a squawk, and a startled noise listed. According to a comment in the script, "strider footsteps are heard everywhere in map". There is also a HUD icon named "hud_loc_chicken". There is also a particle named "chicken.pcf", and a sound effect of the Team Fortress 2 grenade launcher named "chicken_tube". The sound file can be heard below.
This NPC was likely a part of F-Stop in some form.
An unused turret with the unique ability to shoot a light blue laser that causes damage to the player. Unlike the Thermal Discouragement Beam, the laser does not impede the player's movement, and does not affect the game environment or mechanics. The turret does not appear in any of the final game's maps, but can still be spawned using the developer console. When spawned in the final game, the lack of a model means that it shows up as a bright blue "ERROR" sign, although it still retains its laser function.
Pre-release screenshots show that the turret originally didn't hover, but was attached to the ceiling via a wire, and used the model of the curiosity core from Portal. It could also be carried around like a normal turret.
Some of the items in the motel room at the start of the game could fold out. Likely a leftover from the aforementioned F-Stop. As seen in this demo intro, furniture would fold in order to reveal the room being a simulation.
The particles used for the cut Pneumatic Diversity Vent (see the prerelease page.) still exist in the final game under the name broken_tube_suck. As the vents are not used, neither are the particles. While this was to be used for the Diversity Vents, they are actually a leftover from Portal - specifically in the second escape map when the player has to smash a pipe to get access to the cubey goodness within.
The game has coded and modeled entities for small fragile spheres called "futbols". It comes in two versions: glass, and bomb. There are special spawner entities, with models, for both. The bomb version was reused for the redirectable bombs in the final game with a different model. Judging by the map "mp_futbol_01" these are very likely remains of the Competitive Multiplayer Portal 2, which was reworked into Co-op very early on as the matches quickly became hectic and confusing. The objective would have been to redirect a bomb of sorts into other players using portals.
The game has unused point indicators as seen in the first second of the video. Probably used for multiplayer testing or the early multiplayer concept with the Futbols.
Was the editor version "9" when the DLC first came out?
Present in SteamApps\common\Portal 2\sdk_content\puzzles is devtest.p2c, a Perpetual Testing Initiative custom puzzle made by the developers to test the editor. You can play and edit it by copying the file into SteamApps\common\Portal 2\portal2\puzzles\your_steam_id. It appears as a nameless entry under Create Test Chambers. It has no image, and appears to have every object available in the editor placed in a room the same size as, and obviously based on, the blank template. The line "Version" (which is the version of the editor the puzzle was made in) has the value "9", rather than "14".
Three of the Cube Droppers are missing connections. This is either because the level was only meant to test the editor rather than gameplay, or Cube Droppers had different settings in earlier versions of the editor.
Unused Palette and GUI Icons
Upload the rest of the icons.
The folder portal2_dlc2/materials/puzzlemaker/palette contains all of the item and GUI icons, plus several extras not used in-game. These include a crusher, a large Faith Plate, and an unidentifiable "ghost" panel.
An unused variant of the fizzler which destroys paint passing through. The entity itself (trigger_paint_cleanser) is used in-game to prevent using paint in certain locations, but it never appears as a fizzler. An unused particle (paint_cleanser.pcf) is present in the game files as a red version of the fizzler from the original Portal. Additionally, Paint Fizzler instances can be found in the instances/gameplay folder.
Interestingly, the only cut map referencing the Paint Fizzler in its name is a co-op map. This implies that paint fizzlers may have been co-op exclusive.
Scrapped Paint Gun
During development, the developers used a paintgun for gels. The gun was from a student game called Tag: The Power of Paint, in which the player could paint the environment to add and remove paint with various effects. The Repulsion and Propulsion Gels are two of the paints actually used in that game. Developer commentary mentions that the player would be given the gun, so they could paint the grounds and walls to complete test chambers. However, it would cause confusion towards players not knowing exactly where to place what paint, as well as destroy the aesthetic of the game.
It was ultimately removed in favor of keeping the game simple by using only the Portal Gun to manipulate puzzles. The idea was revived in the standalone release of the mod Aperture Tag in 2014, which was approved by Valve themselves and is available through Steam. The paint gun seen within that is not a C++ entity though, but simply changes the Portal Gun model and uses standard Source entities to make it shoot paint.
Unused Map Names
All single player maps have proper map names, including ones not normally playable in Challenge Mode. These maps and their names are listed below. The map names are stored in Steam\SteamApps\common\Portal 2\update\resource\basemodui_tu_english.txt.
|Map Name||Translation Token||Challenge Mode Name|
In addition, if the player adds those maps to the Challenge Mode map list (Steam\SteamApps\common\Portal 2\portal2_dlc1\challenge_maplist.txt) the game makes use of those map names in the Challenge Mode menu (except the Credits map, which never appears). They are fully playable although they lack dedicated goal points. The "Level Completed" screen will come up when the player hits the level transition trigger. The Steam server correctly records the player's times and scores. The Community Data chart is also available on these maps, with the somewhat expected number of Fewest Portals records.
Portal 2 keeps a list of resources used in each map under the Portal 2\portal2\reslists folder. Resource lists and sound lists exist for every single-player and co-op map in the game, as well as many, many extras that do not correspond to any map in the final game. Oddly enough, these resource lists don't exist for the Art Therapy co-op DLC maps or custom maps made in PeTI or Hammer, so these files are possibly not used at all?
Interestingly, there are way more scrapped co-op map ideas than scrapped single-player maps. The used single-player maps all stick to a "sp_a#_MAP_NAME" convention, with # being the "act number" somewhere between one and five. This must have been a late addition, because the old prototype maps don't follow this convention.
You can also see hints of unused concepts in the map filenames, such as adhesion gel ("paint_stick") and rockets.
Unfortunately, these files contain nothing of value, and the maps themselves do not exist in the files. So you can't play any of these concepts, or even see what they looked like. Bummer!
