Last week, word came that Valve would finally be releasing new DLC for Portal 2. Well, that day has come and the new DLC, titled "Peer Review," is out now on Steam, Xbox Live, and PlayStation Network. If you have Portal 2 installed on your PC or Mac, the DLC should automatically download whenever you start up Steam. XBL should have the DLC now, while the PSN should get it as soon as the PS Store updates. The DLC is entirely free, even on the consoles, so you really have no excuse to not pick it up and continue the story of Atlas and P-Body as they explore a new test track. There are also new single player and co-op leaderboards included in the DLC, so you can see how quickly you finish a level compared to the rest of the world. If you don't happen to own Portal 2, you can pick it up on Steam for the low price of $14.99. The game is 50% until October 6th, so you better hurry to pick up one of the best games of the year.
