Bulkypix has announced their zombie survival iPhone shooter Undead: The Last Refuge, set to arrive on the app store sometime this month.

The dev claims the game can really show off what the iPhone 3GS is capable of, as you’ll try to survive for as long as possible in a semi-fortified structure with the undead surrounding and closing in. The title features OpenFeint scoring with Facebook and Twitter intergration for high score posting. You can check out a gameplay video of the title here.

No pricing details or exact release date as of yet, but expect it to pop up on the App Store sometime in May. From the press release:
