History VideoGame / PortalPrelude

** [[AvertedTrope 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...)

** The 2023 remaster [[AvertedTrope averts]] this on all characters but [[CreepyMonotone GLaDOS]], for obvious reasons.

* SuspiciouslySimilarSubstitute: Abby is based on Chell's model.

* 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 [=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.

* 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, 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.

* SilentProtagonist: Abby

''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 ''VideoGame/Portal1'' and three years before ''VideoGame/Portal2''.

* BattleThemeMusic: "Believe" by The Chemical Brothers is used for [[spoiler:the FinalBoss. According to the credits, [=GLaDOS=] loves this song more than cake.]]

* NoobBridge: Even if you have played ''VideoGame/{{Portal}}'', there are a lot of places you'll probably bet stuck if you don't know what to do. One early puzzle requires to you push forward, crouch, and jump while in midair to clear the ledge.
