Portal: Gameplay Video
May 27, 2009
Portal is a cross between an FPS and a puzzle game. The object of the game is to get the cube (which isn't seen in the video) to the other end of the room, using the portals which are seen in the video. In the video I am just messing around creating the portals and jumping about. Just to demonstrate the main mechanic and attraction of the game.
You can buy it separately, but it more commonly comes in a bundle with Half Life 2 and Team Fortress 2, the bundle is called The Orange Box.
