Words really can't to justice to the originality of this gameplay, so you'd best check out the hi-res version of the trailer here.GameStop wrote:In other situations, you may be under fire by a gun droid. So all you need to do is shoot a portal open over the gun, then shoot a portal open beneath a crate, then watch the crate fall through the hole and crush the gun. It gets even crazier, and the diagrams shown in the trailer showed some incredibly crazy things that you can attempt, like creating a series of Portal so that you're constantly chasing yourself.
(Note: If the hi-res mirror goes down due to traffic, it's big and is on the front page of Digg, you can get the torrent for it here, or watch the lo-res version at Gamespot)
