While fully implemented in the game, the Schrödinger's Cube is not usable in maps, as Valve hardcoded them to change into normal reflection cubes on spawn.
Portal 2 ending skin#
Additional skin slots were added to the reflection cube model and are used for these, though the textures themselves are missing. Fizzling or painting one cube will also do the same to the other one (a behavior which is mentioned in The Final Hours of Portal 2). When a laser enters one cube, it will come out of the cube it is linked to. The cubes would be placed in pairs and linked together. It is implemented as cube type 5 on the existing prop_weighted_cube entity. The Schrödinger's Cube is an unused Reflection Cube variant introduced in the Peer Review DLC.

What byte needs to be changed to enable this? A video of the paint gun can be found here. There are several maps in the reslists) that mention the 2guns gamemode. However, they are no longer implemented and will not spawn in-game. Two entities for the paint gun, weapon_paintgun and item_paint_power_pickup, are still in the FGD. Many paint gun-related assets remain in the game's files, including HUD icons, particles and a console command. The paint gun seen there is not a C++ entity, though, but simply changes the Portal Gun model and uses standard Source entities to make it shoot paint.
Portal 2 ending mod#
The idea was revived in the standalone release of the Aperture Tag mod in 2014, which was approved by Valve themselves and is available through Steam. It was then planned to be brought back in DLC2, which did not happen. It was later planned again as a multiplayer gamemode named 2guns where one player would have a paint gun, and the other a portal gun, and could swap them, before being removed again. It was removed from singleplayer early on in favor of keeping the game simple by using only the Portal Gun to manipulate puzzles. However, it would cause confusion towards players not knowing exactly where to place what paint, as well as destroy the aesthetic of the game. Developer commentary mentions that the player would be given the gun, so they could paint the grounds and walls to complete test chambers. The Repulsion and Propulsion Gels are two of the paints actually used in that game. There's a texture intended for the Hammer map editor that would indicate swapping your portal gun with the paint gun.ĭuring development, the developers used a paintgun for gels, similar to the student game called Tag: The Power of Paint, in which the player could use a gun to paint the environment. It has never been officially used by Valve, who simply call it "sticky gel" or "stick paint". It is often referred to by the community as "Adhesion Gel".
Portal 2 ending code#
The code for sticky gel is still in the game, although disabled by default, and can be re-enabled with this mod (archived download) that requires an older version of the game. It was later shown by Valve with the effects working in a presentation here. A video of the leftovers (albeit after the effects were removed) can be found here. Because of this, several community map-makers have tried (with varying success) to implement it in their maps. All of the Sticky Gel-related textures and particles remain in the final game. The gel is purple, however it is not known whether this would be the final color. This led to it being cut from the game and eventually replaced by reflection gel in the PeTI update.

While this may sound neat, it proved to be disorienting and cause motion sickness among playtesters. Going through game_sounds_music_a2.txt will reveal the internal, possibly original, name for the "Turret Wife Serenade" track.Ī gel which, when used with portals, would allow the player to walk on the walls and ceiling of test chambers. This one is listed along with them, but is never chosen. The ending track was composed by none other than singer-songwriter and self-described geek Jonathan Coulton and sung by Ellen McLain (GLaDOS).Workshop map made in the Perpetual Testing Initiative will randomly choose between five music tracks. Before you play the video below, please note that it could spoil the ending of Portal 2 for you as it contains the actual song that plays at the end of the game and the ending cinematic.
