I’m always fascinated to see the inventive methods that games and app companies come up with to kill off zombies because they all know we love killing those zombies! Today’s tip of the hat goes to Promethium Marketing Group and UK development studio GrinLock, the team behind Tweet Defense, which is a game that combines Twitter stats and zombie killing to make a unique Tower Defense game. The game features 10 levels, 5 zombie types, including the viral marketing zombie and zombie twins Gu and Ga, and 6 tower types, including the unique BOOSTER tower that enables you to use Twitter celebs to boost your tower stats. So how does it work exactly? Here’s Tweet Defense’s executive producer, Nelson Rodriguez to explain:

“We wondered what it would be like to take your social network and your activities there and turn it into a game. We ended up with a full-on Tower Defense game that uses your friend list and your tweeting activity to impact how powerful your towers are.”

Tweet Defense is available now for download from the Apple iTunes App Store for a limited sale price of $0.99/£0.59.
