Remember the free Portal 2 downloadable content that was supposed to come out in the summer? Well, it's called "Peer Review," and it'll finally be available for download on PlayStation 3, Xbox 360, and PC on October 4.
"Peer Review" has Atlas and P-Body pairing up for more action in a new co-op test track. It also adds a challenge mode for both single-player and multiplayer with leaderboard support.
Speaking of free Portal 2 stuff, Valve hooks people up with the last volume of the game's soundtrack. Cheers to complete soundtracks!
Speaking of peer review, how would you evaluate Valve now?
