We first reviewed Limbic Software’s Zombie Gunship (Free) over a year ago, and since then, the game has only gotten better with updates. If this is the first you’ve heard of it, here’s the game in a nutshell: You know those awesome AC-130 levels from Call of Duty games? Well, take that, add zombies, done.

This update adds a highly requested “no humans" mode, so you can basically just go nuts shooting everything that moves. If you’ve been annoyed by pesky humans running from zombies and consequently getting in the way of your bullets, you can activate the “Human Sequestration Advisory System."

In other Limbic Software news, they just opened an online store where you can buy various Zombie Gunship merch’. Their shirts are printed on those stupidly nice American Apparel shirts, and currently come in three different designs.

Additionally, Limbic’s Arash Keshmirian and Kevin Pazirandeh (of Zombie Highway (Free) fame) have put together a new podcast called “Walled Garden Weekly". It’s awesome, and you should subscribe to it if you’re looking for another iOS-centric podcast to listen to.
