|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 appears to have been just for a demo done for the PAX event.|
|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.|

Mel was originally to be the main protagonist of Portal 2 before being moved to multiplayer and, unfortunately, eventually cut altogether. Her only valid instance of her appearance (physically) is from a retexture of a Chell model from the original Portal. Her appearance was that of a blue-eyed, blonde haired woman with a light blue jumpsuit, pink gripped Advanced Knee Replacement units, and a Caucasian skin tone. Though she and Chell were meant to appear in multiplayer, they were eventually replaced by Atlas and P-Body.
When Mel was still the main protagonist, it was found that playtesters became disappointed at the fact that GLaDOS didn't recognize them. After being changed to a multiplayer character, the consequence of dying without respawning often made playtesters afraid of experimentation. Thus, Chell was re-introduced as the main protagonist. Atlas and P-Body were used for multiplayer, and were shown being taken apart and re-assembled in different areas to help players (and playtesters) overcome any fear of not being able to respawn. This also creates a reasonable excuse for being able to respawn.
A possible early version of Mel is seen in Portal 2: The Final Hours as a random character in an early jumpsuit design for Chell in Portal. This character had a different face and overall younger appearance than Chell, and is therefore assumed by many to be Mel. Her placeholder texture is still in the game and separate from those of Chell, but lacks animations (although they are specified, they don't exist anymore).
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 be replaced by reflection gel, although the textures are still in the game.
Because the textures are still in game, 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 turning off SmartEdit and setting the gel type to -1. It replaces the Adhesion Gel that was dummied out before the PeTI update was released, but all effects of it are still on this gel.
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.
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" that is empty, but presumably would contain a chicken or some form of chicken-related paraphernalia. 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.
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 can still be spawned with cheats, and can be found in-game by using noclip and flying behind the level sign of level 1/19 and looking left. If you go near it, it will give off a blue effect and any captions enabled will scroll left.
Prerelease 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. Unfortunately, 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.
Very early in development, when Portal 2 was still F-Stop (circa 2007), mannequins were prominent where turrets are now. The F-Stop device and mechanics were apparently different, and have been elusive. The mannequins were to be used during F-Stop testing as turrets are used in Portal Gun testing. According to Portal 2: Final Hours, the mannequins were sentient robots who were to rise against Aperture Science.
Along with the F-Stop mechanic, the prequel idea, and the F-Stop device, the mannequins were ultimately cut, although one remains in a deactivated state for testing of turrets.
Back when the game was in early development, Mel was still running around Aperture as the protagonist, and Cave Johnson replaced GLaDOS. The Gyroscopic Liability Absolver and Disc Operating System (otherwise known as Betty) was to introduce the player to new test chambers. She would "roll out after [Cave Johnson] had described the test" and void Aperture Science of any liabilities that may be found during testing. As shown in the image, the early model for Betty was a small morality core attached to a desk lamp with wheels.
Interestingly, the acronym of her name (GLAaDOS) was to be the only reference to GLaDOS, the antagonist from Portal and the final version of this game.
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, seen in a prerelease demonstration video, still exist in the final game under the name broken_tube_suck.
The tubes are not set up to suck up in the final game, but the tubes are used to dispense some objects and to carry the player in plot sequences.
The testing apparatus can be recreated using the used tube props, standard Source engine entities, and the unused particles. Pieces of the wall being sucked away, as in the video, would have to be specifically set up and arranged at points in the map, and wouldn't be as dynamic as it appeared.
While this particle 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. 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.
Devtest PeTI Puzzle
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.
Early Aerial Faith Plate
Add an picture of the final and early design's of the Faith plate.
— Marc Nagel
As seen in the E3 demo of the Aerial Faith Plate, the model was changed to what we know and love today. In the developer commentary, it is said that it changed because playtesters had trouble recognizing it.
" The faith plate was originally a robot arm model which we hurriedly placed into the maps to see if the gameplay was fun. Over time, it became apparent that playtesters were struggling to tell the faithplate apart from the standard arm, so we replaced it with a new design. It was meant to be a simple heavy weight which was flung upwards, propelling the player. The length is meant to imply a direction, so the player knows the intended flight path before they step onto it. We experimented with foot marks and treadplates on the design, but it quickly became confusingly busy, so we kept the design simple. "
Pneumatic Diversity Vent
A mechanic intended for testing only. Intended for sucking up objects into a vent and spewing them out somewhere else.... or just remove them forever. When hacked in normally, it doesn't work. It only works as intended with the usage of Bee Mod, or the Hammer. According to unused screens, the vents could carry a variety of objects, including the cut Hover Turret, chairs, tables, Companion Cubes, and open Fire Turrets.
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 paintgun seen within that is not a C++ entity though, but it makes use of the game's "Vscript" squirrel implementation.
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|
|NOTE: Do not appear in Challenge Mode menu even with hacking|
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). 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 most of the Art Therapy co-op DLC maps, 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, like adhesion gel ("paint_stick"), "2guns", whatever that is, 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!
