Anomaly: Warzone Earth, the "reverse tower defense" game of disabling defenses around alien spacecraft (and the game with the most "three random nouns stuck together" title since Sniper: Ghost Warrior) is heading to XBLA on April 6, perfectly situated within the announced "spring" release window. It'll cost 800 Microsoft Points ($10), itself an anomaly in a sea of $15 games.

Speaking of anomalies, check out the trailer above, released in honor of the XBLA release date announcement.
