Valve, changed the world with their first game. Expanded the art of video game story telling with their second. Now their amazing physics engine gets a work out in PORTAL!
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.
Amazing stuff! I can’t wait until HL2 - Episode II.
