Cro-Mag Rally from hush-lipped Citizen 12 Studios has finally passed the finish line and is now available on the Marketplace.

Cro-Mag Rally enjoys the distinction of being the first Xbox Live kart racer on Microsoft’s mobile platform. Just because the game’s prehistoric doesn’t mean it’s light on content, as it’s got two playable drivers, multiple vehicles, and nine tracks to race through. These include such varied locations as The Great Wall of China and the lost city of Atlantis. Not only that, but there are lots of powerups with which to assault your fellow racers. Hey, they probably had it coming.

Cro-Mag Rally costs $2.99 and there is a free trial. Stop over here (Zune link) at the Marketplace to get it.
