Portal 2 DLC Finally Hittin On October 4

First we were told we would get the Portal 2 DLC in Summer, then we were told mid-September and now we're being told something else. The free DLC for Portal 2 will be available to download next weekon October 4.

"Peer Review", the name of the DLC, focuses more on the co-op mode, but it will continue to storyline of the game. The only thing single player is getting is a challenge mode that tracks down online scores for a leaderboard, co-op will be getting the same things as well.
