Release Date: Now Available | PS3/360/PC
Portal was originally packaged with The Orange Box, available on the 360, PS3 and PC, and is now being sold separately for the PC. For any of you that didn't pick up The Orange box (which you should have, because as far as value goes, there is no better bang for your buck) you now have the opportunity to get the newest addition to Valve without the Half Life series package.
"Portal™ is a new single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay.
The game is designed to change the way players approach, manipulate, and surmise the possibilities in a given environment; similar to how Half-Life® 2’s Gravity Gun innovated new ways to leverage an object in any given situation.
Players must solve physical puzzles and challenges by opening portals to maneuvering objects, and themselves, through space."
