The Doomsday Wasteland Starts with a Flat Sign.

In the first year of the Cataclysm, a "zombie wave" suddenly broke out around the world. Humans were infected with alien viruses and turned into zombies. Animals with levels ranging from F to SSS and "alienated beasts" were mutated by radiation, and their strength corresponded to the level of the evolver. Human civilization collapsed instantly. Survivors are scattered in ruins, safe zones or in the wild. Resources are extremely scarce, morals are corrupt, and the law of the jungle has become the norm.
