Another co-op release hits Xbox Live Arcade today.  Elements of Destruction features 2 player co-op, both local and over Live.  If you were a fan of unleashing natural disasters on your poor, unsuspecting Metropolis in SimCity back in the day, then you might want to check out Elements of Destruction.  Players control lightning, earthquakes, and other forces of nature in order to cause as much mayhem as possible.  Elements of Destruction will set you back 800 points, or $10 bucks.
