Portal 2 News: Portal 2's DLC arrives October 4 across all platforms, but you can download the final volume of the soundtrack today.
Portal 2's first DLC is called ?Peer Review? and the release date is October 4 on Xbox 360, PS3, Mac and PC. Along with this announcement, developer Valve has made the final volume of Portal 2's soundtrack available for download today, also for free.
?Peer Review? will include co-op and single-player content. Valve has promised further adventures of the robotic duo Atlas and P-Body, and more GLaDOS. There will also be a single-player and co-op challenge mode, which will feature online leaderboards.
Even though it's a sequel, Portal 2 is the year's most original big-budget title. It's only $30 on Steam, and for another five dollars you can get it bundled with the original.
Exclusive to PlayStation 3, Portal 2 supports cross platform multiplayer. That means you can play online with computer gamers. In fact, PS3 copies come with a free download of the game for Mac and PC.
