Doomsday Vanguard

In the year 1023 on the continent, the Z virus was maliciously leaked by an organization with the intent of overthrowing the continent's regime, plunging the world into the brink of panic and destruction. This dreadful evil disaster distorted everything that existed. Life forms infected by bacteria became deranged, attacking everything around them. The entire continent was nearly laid to waste, with only a few cities remaining, fighting against the virus and seeking a cure.
