Portal - First Look Movie

Valve has released the first trailer for Portal, the puzzle mini-game that will accompany Half-life 2: Episode Two. The video is a rather surreal attempt at humor and is shot as a company's instructional video.

Portal is a new type of single player game that changes how players approach, manipulate, and surmise the possibilities in a given environment in a manner similar to how the Gravity Gun changed our approach to how an object may be leveraged in any given situation.
