If you're an octopus pirate, you can't just sit back when you're attacked by UFOs — you have to fight them off! (There's a sentence I never thought I'd type.) And in Octo's Tales by Granet Entertainment, that's exactly what you do.

Gun Down Elves with Shotgun Santa

Fight the Undead with Zombie Mansion
First person shooters are starting to make their way to the App Store. One excellent option is Zombie Mansion. The game has its flaws, but it is a good effort at bringing some of the time-honored tradition of blasting zombies to your iPhone or iPod Touch. The game begins by placing you trapped inside, go figure, a mansion. Fortunately you are armed with some sort of magic stick that fires energy balls at the undead.
