This page details prerelease information and/or media for Portal 2.
| This article is a work in progress.
...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.
|
| This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?
Notes: This page is missing a huge number of pre-release videos and content, alongside some bad grammar and next-to-no referencing or sources for information. |
After the release of The Orange Box, Valve took a break from working on games to experiment with other projects, at the request of Gabe Newell. Some of these projects included potential sequels and spin-offs of Portal.
Timeline
| To do:
- Try to start expanding this timeline and provide specific dates for when much of this happened (if possible), provide details and preferably not "eras".
- Clarify what Art Therapy Super Tests mean
- The Development Limbo apparently happened, between the end of F-Stop and start of Core Hub
|
August 2007 - March 2008 Directed Design Experiments - Various experiments were conducted to improve the Source engine. This stage is not really related to Portal 2 development.
December 2007 - December 2008 - F-Stop - Valve's fifth experiment featuring a camera. This would end up as a prequel to Portal.
January 2009 - October 2009 - Valve's first attempt at a sequel to Portal. The story would have been about the Personality Cores taking over Aperture Science and using them to repair GLaDOS. Portal fans named this stage Core Hub after the hub (Central AI (GLaDOS) Room).
January 2009 - 2010 - Experimental - When Valve began work on an actual sequel to Portal, this stage was focused on creating new features for the game, many of which (light bridges, excursion funnels, aerial faith plates, and lasers) remained in the retail game.
Summer 2009 - The developers of Tag: The Power of Paint were hired by Valve. Paint (gels) development had begun, although in separate game, based on Portal 2.
November 2009? (confirmed late 2009) - Gels were merged into the main game.
November 2009 - June 2010 - Storyline rework began, making the hub concept to be scrapped. The storyline was closer to retail, but there are still differences. Overgrown chambers style development has started. Portal fans named this stage Multi-Core after the idea of multiple cores that would be merged into Wheatley later.
June 2010 - August 2010? - The team merged all the other cores into Wheatley and had him survive his supposed death. He was immediately set to become the new antagonist of the game. The underground was a good candidate to suit the origin of the gels in the game.
September 3rd, 2010 - The Full Co-Op Trailer was shown off at PAX 2010.
September 2010 - December 2010 - The underground was rapidly finished and Act 4 began getting crunched on. Only Chapter 8 gets completed, and the Art Therapy Super Tests get canned. PotatOS was rewritten to be nicer to the player. The sp_aX_ convention was introduced.
December 11th, 2010 - The intro to co-op was shown off at the 2010 Spike Video Game Awards.
December 17th, 2010? - The Content Lock was established. Optimizations began across the whole game.
March 9th, 2011 - Preload PC build got compiled.
March 16th, 2011 - Xbox 360 Gold build got compiled.
March 25th, 2011 - The first of the Aperture Investment Opportunity promotional videos called "Panels" was published on YouTube.

| F-STOP
Valve's fifth game experiment. |
| Core hub
Now a sequel to Portal, this went from one core to multiple cores before returning to one core. |
| Multi-Core
This is where the game and its storyline get similar to the retail one, but it's still different. |
| Pre-Retail
This game is starting to look more closer to the final game, albeit with some differences. |
