Doomsday Era: from the Ashes

A "Black Mist Catastrophe" breaks out around the world. 99% Of humans are infected and mutate into zombies. Animals and plants are alienated. The "Shadow Eater Beast" that devours everything is born in the black mist... The survivors discovered that "source energy crystals" can resist the erosion of black fog, and some humans awakened special abilities, called "source energy users"... The world is divided into three major areas: the black fog restricted area (the lair of zombies and shadow-eating beasts), the ruined city (the stronghold of survivors), and the unpolluted mysterious "pure land"...
