We're still waiting for Tekken 6 to get its co-op mode via a free piece of DLC, but now might be the time to purchase the game as Amazon.com has it on sale for only $20. Both the Xbox 360 and PlayStation 3 versions are discounted.
If you're looking to snag one of the awesome Fight Stick Bundles that come with the game, a Hori wireless arcade stick and a hardcover art book; that's been discounted to $78. That's a total steal as the stick itself has retailed for almost $90! The deal ends when stock runs out or the end of the day today!
