The Apple Design Award-winning iOS "tower offense" title Anomaly: Warzone Earth has just been updated with iPad-sized retina graphics, so it'll be prettier than ever when you boot it up on your shiny new iPad 3 iPad.
Even if you don't have the new 'Pad, though, you can pick up the game's big and little versions for 50% off. That's $1.99 for the iPad version and $.99 for the iPhone. And the price cut lasts until the celebration's over (meaning we don't know how long it'll last), so act fast if you're on the fence.
Anomaly: Warzone Earth blends action and strategy for a genre the developers have named "tower offense". It was recently released for Xbox Live Arcade, as well, though that version doesn't appear to be on sale.
