VVelcome To Portal Industries
Hey Wyther, remember that Prey game you were talking about? Yeah, it kinda sucks. This here is the Acme Portable Hole© game that has a similiar concept and this trailer is pretty 'dope' or 'fucking dope' as the kids say.
Portal will be a free bonus game for people who get Half-Life 2: Episode 2, which is a mouthful, and has a nice trailer of its own.

dope 2-3 dope.
it's based on a much less cool looking puzzle game (but still very cool) narbacular drop done by some digipen students, I believe they are the same people who made this, becuase i'm pretty sure valve hired all the group after they graduated.
