Ruthless zombies pounces on our country. They continuously evolve to become more and more aggressive. Our shellfire almost can’t stop them. Dear brave soldiers, your country needs you. We need you to undertake this great mission--PROTECT COUNTRY AND DESTROY ENEMIES! You have to build a solid front, otherwise these zombies will go across the restricted area to evade our territory if careless and you fail.
