A World War ZA (World War: Zombie Apocalypse) has come. The Undead Brigade and The Demonic Union are trying to attack the ROBLOX World and destroy our precious Core, which is containing the most vital energy and uses as a power source for our world. It is better to protect it! Use your Weapon, drive a drivable vehicle, pilot a Jet, morph into NPCs, collect the Coin and spend it for the base upgrade and more powerful weapon. Soon you will face a Zombie King who is commanding all of the zombies to assault us.
