If you need any reason to play Portal 2 besides to enjoy the puzzle gameplay as well as the unique comedy contained in the game, then how about completely free DLC. Valve announced earlier today that they will be releasing the free DLC next month on October 4th on the PlayStation 3, Xbox 360 and PC.
The DLC is going to be named Peer Review and will provide more missions for P-Body and Atlas and even give GLaDOS a bit of screen time as well. There are a few leaderboard single player and co-op missions to see who will be able to obtain the best time. So better dust off that copy of Portal 2 because it is going to be getting some playtime next week.
