Well, this news should make Portal fans pretty GLaD(OS). The first set of Portal 2 DLC will be released for free on October 4th, 2011.
The add-on is titled, “Peer Review,” and consists of a brand new co-operative test-track for Atlas and P-Body to get through, as GLaDOS insults them the whole way. The DLC also brings a single-player and co-operative Challenge Mode to the game, along with community leaderboards.
Portal 2: Peer Review releases next Tuesday, October 4th, on the Xbox 360, PS3, and Steam. While you wait for Tuesday to come, be sure to download the third and final installment of the Portal 2 soundtrack, which is also available for free. You can download that by clicking here.
