In between missions, you'll stock up in the Upgrade Store, increasing the power of your weapons and armor. Then it's back to more zombie-shooting fun! With 19 levels and lots of different zombies, Zombie Storm is non-stop zombie slaying madness! Remember, you don't have to save all the citizens - you can pass the level if even one is left standing at the end. So find your favorite citizen and follow him around, blasting enemies that try to convert him to the undead.
