Portal 2 PAX Co-op videos

The co-op portion of the game will just be adding to the length of Portal 2.  With co-op two players can go puzzle solving via internet, LAN, or split-screen. Each player will be controlling a test robot, armed with a portal gun. Just like in the single player the portal gun will shoot two portals, so that's a total of four portals between the two players. Well that's enough explaining here's some videos.
