Anomaly: Warzone Earth launched back in April for the PC (feel free to give the demo a download, if you're so inclined). But it's coming to iPad in four to six weeks, and at last week's EA Summer Showcase day I got a chance to see how the transition was going.

It's no surprise that tower defense games really lend themselves to being played on a touch-screen interface. Poking and prodding to move troops around and interact with the game world make those games a cinch to play. As I learned from my time with Anomaly: Warzone Earth, the same is true for tower offense games as well.
