Zombie Attack Free is a free preview of Zombie Attack, a "tower defense" real-time strategy game in which you fight off a horde of zombies with strategically deployed gun turrets. An endless stream of zombies (punctuated by progressively more difficult levels) rushes across a field, trying to reach and attack your humble shack, as you run around on the field (by tilting your device, or using touch-and-drag controls) placing and upgrading gun emplacements. You earn money for every zombie you drop, and the game ends when the zombies destroy your shack.
Like other tower defense games, the heart of Zombie Attack is resource management, as you choose between when and where you should build turrets, and whether you should upgrade existing guns or instead spend on building increasingly expensive new ones. What makes the gameplay in Zombie Attack so rich, though, is the added arcade action as you run around on the field--because you can draw zombies toward you, and because any turret you stand next to will do 50 percent more damage. This game is a solid value for real-time strategy fans, with fun 3D graphics and good sound effects, and the affordable paid version offers even more options and turret types.
