Hank the Tank is out here on the battlefield blowing zombies up. Use the left and right keys to move and space to shoot. Annihilate all the zombies before they annihilate you!!! (or just reach the end) Click on the background to change the color. (By the way the tank is viewed from the top, the turret has turned sideways and it is facing the left)
