Portal went from just one part of the Orange Box collection to the 2007 Game of the Year. Imagine what the franchise will do when it has the stage all to itself. Valve delivers another legend-in-waiting by refining and expanding a concept that simultaneously shatters both convention and the laws of physics. Use an experimental portal device to open entrances and exits as you travel through the eerily perfect world of Aperture Laboratories. Battle the sinister AI enemy GLADoS as you face the puzzle-filled challenges of the lab's test chambers. The single-player story features voice acting from The Office's Stephen Merchant while the co-op saga offers a story all its own.
