Portal 2 Peer Review DLC Now Available on Xbox Live

The first downloadable content pack for Valve’s Portal 2 has been released onto Xbox Live.

Entitled ‘Peer Review’, the free DLC  is free with the download size weighing in at 1.37GB. The developer recently summarized Peer Review upon its announcement:

In “Peer Review”, you and a friend will continue the story of loyal bots P-Body and Atlas as you puzzle your way through a mysterious new co-op test track and once again match wits with GLaDOS. The DLC also features a single player and co-op Challenge Mode, and leaderboards to compare Challenge Mode scores with friends and the Portal community.

The Peer Review downloadable content will soon go live on the PlayStation Network upon the PlayStation Store’s weekly update. Portal 2 has, since its mid-April release on multiple platforms, sold over two million copies.
