Welcome to the Doomsday Hero. Toxic gas was unintentionally spilled during a significant biochemical experiment, severely polluting the city. Everyone is now infected and has turned into a zombie, with very few people remaining. The warriors could only carry on fighting in order to safeguard the few survivors because the temporary antidote could not yet be created. Contribute to the purchase of the soldiers' equipment so they can survive this trying period. Help the warriors use strong skills and equipment as well as more advanced weapons and mounts. To save every survivor on earth, you must team up with other warriors to destroy all the zombies you come across. Upgrade your weapons as you go for maximum damage and survival through the game's thrilling missions.
