Does the screenshot say it all? If not, let's be clear: you should check out Dead Rising 2. Especially if you're still hanging onto that Xbox Live Gold account of yours, because the game is free as of today through the Games With Gold program.
That's not all, either -- Dead Rising 2: Case Zero, the standalone DLC that helped ease us into Chuck Greene's story of being a good father and sometimes riding a tricycle in his boxers, is also a part of this promotion. Be sure to play it first if you want to carry over PP, clothing, and Combo Cards for a little head start in the full DR2.
These will remain free through the end of August, so don't take too much time.
