History VideoGame / PortalPrelude

* {{Bowdlerise}}: The RTX remake removes all instances of profanity (with the exception of a "Damn!" by one of the scientists), as well as Erik's comment about Abby giving them a "reward" if she keeps their assistance a secret.

* ChekhovsGun: Before Abby starts her journey to the Central AI Chamber, she stumbles into the observation room of Test Chamber 06 from the original Portal. Through the window she spots a Handheld Portal Device dropped by a test subject who didn't make it. [[spoiler:She'll later need it & others from a storage room to defeat [=GLaDOS=].]]

** [[spoiler:[=GLaDOS=] floods the Enrichment Center in neurotoxin, before having a morality core installed.]]

* DoomedByCanon: [[spoiler:You can not prevent [=GLaDOS=] from filling the Enrichment Center with a deadly neurotoxin and [[EverybodyDiesEnding killing everybody in it]], even after you place the Morality Core.]]

In 2023, a remastered version was released on UsefulNotes/{{Steam}} through a partnership with NVIDIA, six months after the latter did the same to the original ''Portal'', having fully re-recorded the voice lines of most main characters.

* RoomFullOfCrazy: Several "ratman dens" exist in the game, some more hidden than others, using identical scribbled ramblings and tributes to the Companion Cube from the original game. Though this predates when "the" Rattmann began hiding, as [=GLaDOS=] is yet to be turned on, the overseers mention another test subject had gone crazy and had been hiding about the facility in a similar fashion.

''Portal: Prelude'' is an unofficial GameMod[=/=]{{Prequel}} to ''VideoGame/Portal1''. The game takes place before [=GLaDOS=] was activated, when tests were monitored by real Aperture Science employees. The game is notable for being [[NintendoHard significantly more difficult than the original]]. It was developed by a team of three in 2008, just one year after the main game and three years before ''VideoGame/Portal2''.

* TheStinger: [[spoiler: As a nighttime storm rages, someone, presumably Abby as she grunts with a female voice, slowly walks up to the Aperture parking lot exit booth seen in the original ''Portal'' ending, before collapsing to the ground. As her vision fades in and out, the lightning flashes to show G-Man standing in the booth...]]

** Averted with Erik, who shows signs of being sadistic and enjoying the sight of test subjects dying. (On the other hand, he's also the happiest of the bunch when you reach the final chambers and, eventually, complete them...)

* DullSurprise: Thanks to the [[SyntheticVoiceActor computerized voices]], there are many hilarious moments of this. This is [[AvertedTrope averted]] in the remaster however.

* AdaptationalBadass: Unlike in her debut game, [[AIIsACrapshoot GLaDOS]] is capable of directly attacking Abby during her boss fights, rather than having turrets and neurotoxin do it for her, and possesses such weapons as electric shockwaves, laser beams, and a tractor beam.

* AmbiguousEnding: [[spoiler:Did Abby die? Who was the masked scientist dragging her outside? Did the G-Man have something to do with the recent disaster involving [[BigBad GLaDOS]]?]]
