Free Portal 2 DLC coming October 4

Oh my goodness, Valve has just made my day with the announcement of the first round of downloadable content for Portal 2 hitting Steam, Xbox Live, and the PlayStation Network October 4. Top that with the fact that it’ll cost nothing and I could just forget about that whole Half-Life 2: Episode 3 thing.

Titled ‘Peer Review,’ the Portal 2 DLC will be co-op focused with P-Body and Atlas returning to their duties to test a series of strange new tracks and face off with GLaDOS. The DLC  will also bring a new challenge mode for single-player and co-op modes, complete with leaderboards to compare – and brag – with friends.
