Anomaly Warzone Earth – 320MSP (was 800)
Anomaly is, in our humble opinion one of the finest games to be released on XBLA in recent memory. It is a fascinating twist on the tower defense genre where you take control of the attackers who must defeat the towers. Those who are yet to pick it up have a great opportunity because it is on sale for a mere 320MSP right now. We don’t know why it is on sale or for how long so pick it up while you have a chance.
