History VideoGame / PortalPrelude

* AmbiguousEnding: [[spoiler:Did Abby die? Who was the masked scientist dragging her outside?]] One theory is that [[spoiler:the scientist was Doug Rattmann, the only survivor of [=GlaDOS=]' attack, though the model used during that scene is female, the only female in the game outside of Abby.]]

%%* BossBanter: [[spoiler:Not surprising, considering that [=GLaDOS=] provides the page quote.]]

* RoomFullofCrazy: Several "raatman 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 [=GLAaDOS=] 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.

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

** The last example occurs in Test Chamber 16 (right after the behind-the-scenes sections). Go inside the button room, throw the cube into the main room, and put both portals in the button room. The current supervisor Peter [[UnintentionallyUnwinnable lampshades your stupidity]], and the game fades to black.

** The G-Man can be seen in several places, but is rather hidden. He's also mentioned by one of the scientists by description.

** [[VideoGame/HalfLife The G-Man]] shows up in a few places.

The current supervisor Peter [[UnwinnableByInsanity lampshades your stupidity]], and the game fades to black.

* OffTheRails: You get to go behind the scenes when one of the test chambers catches on fire.

** Test Chamber 06 requires you to put a cube on a button under a DescendingCeiling. If you allow the ceiling to go all the way down (with you not under it), it will not activate the button; instead, your test supervisor will say that the rules prevent him from giving you another try, and end the test.
** A similar game over occurs in Test Chamber 08; if you let the ceilings descend under you to the point of no return, Erik will tell you that he always wanted to kill you, and activate the disintegrator.

* TooDumbToLive: [[spoiler:In the final cutscene, a scientist is waving his arms around frantically in front of [=GLaDOS=], practically begging to be shot by a deadly laser.]]

''Portal: Prelude'' is an unofficial GameMod[=/=]{{prequel}} to ''VideoGame/{{Portal}}''. 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 ''Portal'' and three years before ''Videogame/{{Portal 2}}''.

* TheCameo: The G-Man can be seen in several places, but is rather hidden. He's also mentioned by one of the scientists by description.
** [[Anime/DomoTV Domo]] also appears as a drawing on a whiteboard and in the intro.
* ContinuityNod: The game draws from a lot of continuity from ''Portal'' lore including:

* FinalBoss: Relatively uncommon for mods.

* {{Irony}}: Why is it that the humans' tests are so much more lethal than the ones made by [[SelfDemonstrating/{{GLaDOS}} the murderous AI]]?

* NintendoHard:"[[AC:CAUTION: This game uses advanced portaling techniques and ''may not be suitable'' for EVERYONE. Be prepared to think with portals]]" You have been warned.
** Executed in a strange fashion, though. The game is, indeed, very difficult, but more so from an action perspective. Most of the puzzles (except for a few) are only somewhat more complex than Portal's, but the solutions are much more difficult to execute. (And let's not even talk about the advanced chambers...)
* NonstandardGameOver: Test Chamber 06 requires you to put a cube on a button under a DescendingCeiling. If you allow the ceiling to go all the way down (with you not under it), it will not activate the button; instead, your test supervisor will say that the rules prevent him from giving you another try, and end the test.

* ScrewThisImOuttaHere: Around the middle of the test course, Erik stops observing your progress out of frustration that you didn't die, and waits until the 18th chamber to return.

* {{Bizarrchitecture}}: The first level that introduces gravity-changing panels is set up in a test chamber where everything is turned in random directions.

* LightingReveal: The G-Man appears in the parking lot's tollbooth this way, during TheStinger.

** Domo also appears as a drawing on a whiteboard and in the intro.

** A similar game over occurs in Test Chamber 08; if you let the ceilings descend under you to the point of no return, Erik will tell you that he always wanted to kill you, and activate the disintergrator.

* NightmareFetishist: One of the scientists, Erik, likes to see test subjects die. According to a few other scientists, some of the test chamber hazards were designed by him. Eventually Erik gets [[VictoryIsBoring bored watching you]] and leaves until you reach the 18th test chamber.

Despite the game's difficulty, it's well worth playing, as in the final level, you get to [[spoiler:activate [=GLaDOS=] and see her kill everyone.]] It makes beating those grueling chambers even more satisfying.

** Domo also appears as a drawing and in the intro.

* {{Expy}}: Abby is based on Chell's model.

** While the mod was in development, it was stated that it was an alternative to everyone having French accents.
