It's been a long wait, but the free downloadable expansion for Valve's Portal 2 is available today for the PC, Mac, Sony PlayStation 3, and Microsoft Xbox 360. Featuring a new test track for the game's co-op mode, the new DLC (subtitled "Peer Review") offers new challenges and surprises. Here's 1UP.com's take on the matter:
The DLC is free on all three platforms and includes content for fans of both the solo and co-op campaigns. The story of P-Body and Atlas -- the two co-op robots -- continues in Peer Review "as you puzzle your way through a mysterious new co-op test track and once again match wits with GLaDOS." A new Challenge mode is introduced for both single-player and co-op, and accompanying leaderboards will let you compare your scores with other players.
Free expansions are always appreciated, and free expansions for fantastic games are even more valued. It looks like it's time to dive back into the world of Aperture Science with my co-op partner. Hey, Brad Hilderbrand! Schedule some time this week. We have a co-op challenge to resume. For more on Portal 2, be sure to listen to Episode 46 and Episode 49 of the Power Button podcast.
