You've probably played loads of tower defense games on Android. There's a reason they're so popular, though. See, tower defense games are fun and hard to screw up. Still, the same old thing can get boring after a while. So it's nice to see Anomaly Korea show up and continue turning the genre on its head like its predecessor did. In Anomaly Korea, you play the creeps trying to get past the towers.
Gameplay And Controls
The backstory is that the aliens have invaded and they are not the nice kind that want to invite us to join a galactic federation.
