Zombie Defense, by Dromedary Worldwide Software, is a survival-strategy game that pits four survivors up against hordes of Twinkie flesh-eating zombies. It’s essentially a tower defense game with a zombie-survival twist. You have to keep your four survivors alive for 20 nights until they can be rescued. After each night (level), you get to replenish supplies and search for new weapons. There are many stages to choose from, but your best bet is to play the same stage consecutively, so you can build up your barricades and conserve supplies. Weapons include: a 12 gauge shotgun, .357 Magnum, rifle, etc. Check out our video demo below and if you like the game, purchase it from the Android Market for 99 cents.
Note: developer has noted that Samsung devices may have issues, update is coming.
