A solid release date wasn’t the only thing Valve Software had ready for this year’s Gamescom in Germany.  The biggest addition to the Portal franchise this time around will likely be the multiplayer test chambers that allow you and a friend to work your way through a series of challenges that you couldn’t complete by your lonesome.  It looks like we’ll be assuming the roll of these Bert & Ernie look-a-likes with four different colored portals to dodge the death labyrinths GLaDOS has concocted.

Fresh off the press, Valve also released five screenshots for an high def look into the level design we’ll likely be seeing in the single player campaign.  From the trailers showed off earlier this summer at the Electronics Entertainment Expo, that blue goop is ultra bouncy.  Bouncing drones anyone?
