Press Start Studio’s iPhone anime-style shooter Twin Blades has made the leap onto the Xbox 360 via Live’s Indie Games service, and is now available for download. In the game you take control of a nun determined to rid her city of that awfully popular and persistent group we know as zombies.

The title brings addictive gameplay in multiple environments on a frantic ’31 day’ campaign that includes upgradable weapons. Twin Blades is available now for 240 MS Points ($3) on Xbox Live (46 MB) with a trial version available to download as well.
