This is a great deal for any PC gamer yet to sample Portal's puzzling delights, as after trying the first game you'll be eager to play the second one. You have a gun that fires two portals to travel around the puzzle rooms in one of gaming's most unique experiences. The robotic voice of GLaDOS 'guiding' you through the facility is the star of the show and is brilliantly matched in the second game with the addition of Stephen Merchant. There's a lot of space out there and you'll want to see it all.
