Anomaly: Korea wasn't really a sequel to Anomaly: Warzone Earth, a "reverse tower-defense" game released in 2011 in which you maneuver tanks and convoys around a battlefield and direct them to blow away alien towers. (Lots of people loved it.)

This one really is a sequel. The folks at development studio 11 Bit have just announced Anomaly 2, out for PC, Mac, and Linux this spring for $15. Trailer's above.
