Valve just confirmed that some free DLC is headed to Portal 2 on October 4th. All platforms are scheduled to receive the Portal 2: Peer Review DLC – not too shabby at all is it?
In “Peer Review”, you and a friend will continue the story of loyal bots P-Body and Atlas as you puzzle your way through a mysterious new co-op test track and once again match wits with GLaDOS. The DLC also features a single player and co-op Challenge Mode, and leaderboards to compare Challenge Mode scores with friends and the Portal community.
