The Zombie Last Guard game precedes the Zombie Mission games. The Zombie Mission team responded to the warning. The zombies attack in hordes, and you must work together to save them. Their intention is to kill the servers. Target guns should be activated to secure the servers. You must use the points you earn to upgrade both your own guns and turret towers.
Don't forget to check out the "Market" area for arm upgrades and an extra health bar. The zombies get more powerful with each stroke. Only the ICE Gun will hinder the Fire Zombies. Keep the zombies away from the servers and you'll be able to win the title!
