History Trivia / Portal

* ThrowItIn: ** [[http://www.gamingangels.com/2011/03/pax-east-2011-portal-2-solo-and-an-interview-with-erik-wolpaw/ In this interview]], WordOfGod reveals that the blood splatters weren't meant to be in the game at all. However, they weren't even noticed until too late in development, and were so ingrained into the engine that, by that point, it would have been better to just leave them in the game. Valve went out of their way to remove the blood splatters for the sequel, however, hence its lower rating compared to the original.

** According to the ''Final Hours of Portal 2'', Peer Review was going to contain a single player campaign as well. The original plan was for players to be either ATLAS or P-body, who would be recruited by Rick to stop a brain-uploaded Cave Johnson from taking over the Enrichment Center. [[SequelHook Valve decided it would require too many resources for ''just'' a DLC...]]

* SerendipityWritesThePlot: According to ''Portal 2 - The Final Hours'', the reason the games take place in the ''Half-Life'' universe was to justify the recycled assets from ''Half-Life 2'', which were a lot more pronounced in early development due to the game's small development team.

* CreatorBacklash: ''Portal's'' writer, Erik Wolpaw, is sick of the non-stop cake jokes. In [[http://www.escapistmagazine.com/news/view/101476-Portal-2-Writer-Enough-With-the-Cake-Jokes-Already this interview]], he claims there won't be any references to it in the sequel. However, with [[https://www.youtube.com/watch?v=UgLgm_TN1gE one of Doug Rattmann's drawings in the sequel depicting the cake (at 1:07 in the video)]], and the binary code in Part 1 of the comic translating to "the cake is a lie", Valve seems to have gone back on that. Wolpaw even said [[http://www.telegraph.co.uk/technology/video-games/8359173/Portal-2-developer-interview-Chet-Falisek-and-Erik-Wolpaw.html they couldn't resist putting one joke]].

* SerendipityWritesThePlot: According to ''Portal 2 - The Final Hours'', the reason the games take place in the ''Half-Life'' universe was to justify the PropRecycling from ''Half-Life 2'', which was a lot more pronounced in early development due to the game's small development team.

* InferredHolocaust: Never mind all the researchers that [=GLaDOS=] gassed; "Bring Your Daughter To Work Day" implies that their ''children'' became victims too, or were tested to death. [=GLaDOS=] also manages to sneak in a reference to the multiple disasters of the ''VideoGame/HalfLife'' universe during the FinalBattle and in "Still Alive". It's implied during ''Portal 2'' that Chell herself was the daughter of one of the scientists at Aperture and she was forcibly taken as a test subject by [=GLaDOS=] during her massacre.

** Chell's leg-springs were part of an unused model for an enemy in ''VideoGame/HalfLife2''.

** The sentry turrets have largely the same behavior as ''Half-Life 2'''s Combine turrets.

** Chell actually vocally reacts to impact damage from cubes and other such things. The sound bites used for this are from female NPCs who take damage in ''Half-Life 2.'' In ''Portal 2'', though, this doesn't happen.

* HeyItsThatVoice:
** Creator/EllenMcLain is the voice of [=GLaDOS=], the ''VideoGame/TeamFortress2'' announcer, and the ''VideoGame/{{Half-Life 2}}'' Combine Overwatch. Due to how the Overwatch sounds in ''[=HL2=]: Episode Two'', it leads to a ''lot'' of EpilepticTrees.
** She's also an opera singer in real life.
** Music/MikePatton plays the aggression core.

** The sentry turrets have largely the same behavior as ''Half-Life 2'''s combine turrets.
