Portal 2 is finally getting its free "Portal 2: Peer Review" DLC on October 4th. The Portal 2 DLC pack was originally planned for the summer, but hey, better late than never. The DLC will be released on all platforms: PC, Xbox 360, PS3, and Mac next Tuesday.
Peer Review continues the story of co-op mode allowing gamers to resume their rolls as P-Body and Atlas. I personally identified with P-Body more. The DLC will also include a single player Challenge Mode and leaderboards.
Will this new DLC persuade you to play Portal 2 again?
