[World] The game is set 15 years after a global epidemic caused by an unknown virus in which 99% of humanity was either killed or turned into zombies. In order to survive, the surviving humans have established several “cities” surrounded by high walls to keep the zombies outside. The cities are self-sustainable within the walls, though some brave survivors will go outside the walls to areas overrun by zombies to search for supplies or weapons. Of course, in this lawless world, there are some survivors who choose to kill and plunder to survive. [Features] (A dead world brought to life) We strive to create a convincing post-apocalyptic world with a variety of ghastly and horrific settings not limited to just deserted streets. (Built for fun) Players can collect a variety of materials and parts to construct buildings and maintain the city wall, turning their humble sanctuary into a post-apocalyptic empire. (RTS controls) Players control heroes and survivors to fight despotic powers and explore zombie-infested areas. The skill-based gameplay sees players controlling their armies in real time, allowing them to experience ferocious battles. (Freedom of exploration) Players can freely explore the world map and choose to develop in any direction. At any time and in any place, they can battle other players, or form alliances to occupy resource points. Players can also discover special shops on the world map, which will allow them to purchase rare items.
