Is it any good?
In this terrifying iPhone version of the console game, you're a soldier trapped in a crumbling World War II bunker surrounded by blood-thirsty Nazi zombies. The 3D details and driving Terminator-style soundtrack are good. Zombies roar and stagger realistically. The game isn't quite as slick as other iPhone first-person shooters such as N.O.V.A., and it costs more. But older teen fans of the genre will want it in their collection.
