Unlike its human counterparts, an army of zombies is completely independent of support. It will not require food,ammunition, or medical attention. It will not succumb to panic, desertion, or out-and-out mutiny. Like the virus that gave it life, this undead force will continue to grow, spreading across the body of this planet until there is nothing left to devour. Where would you go? What would you do?
