It's not the deepest game, though it has been hailed as a technical showpiece for Apple's devices due to its crisp, beautifully animated 2D graphics. Players (controlling an awfully violent nun) hack and shoot their way through advancing waves of the enemy flavor of the decade, zombies. There are skill and weapon upgrades, the latter including flame throwers and mini nukes.

A 99¢ download on iPhone, the 360 release of Twin Blades will be priced at 240 ($3) and, so as not to miss a crucial marketing opportunity -- the traditional holiday ritual of decapitating zombies while dressed as a nun -- is slated to land on the Xbox Live Marketplace before December 25. Press Start plans to release DLC for the game down the road, including new levels and bosses. Check out the gameplay trailer after the break.
