Portal Prelude

I am eagerly awaiting this "suped-up" map pack. I don't think it can even be called a map pack. It is a whole new storyline fitting into the Portal canon. Check it out here. The story takes place prior to the Portal game, as the name suggests. Prior to the switch being flipped on Glad0s. The lab is, instead, monitored by humans. As for the rest of the story, game play and how it all ties together will be revealed in 7 days when the game is released.
