Anomaly: Warzone Earth put a different spin on the tower defense genre, giving players a chance to take charge of a plodding convoy as it made its way through fortified enemy defenses across the globe.

This new version of the game by original developers 11 Bit Studios adds six Xbox-exclusive challenges. You can see how it looks in the gallery below.
