Master of the Apocalypse

A sudden global disaster erupts as an unknown virus spreads rapidly. People infected with the virus gradually mutate into terrifying zombies. Their bodily functions deteriorate dramatically, they lose consciousness, and they attack the living on instinct. At the same time, earthquakes, tsunamis, volcanic eruptions, and other natural disasters follow one after another. The world descends into chaos and darkness, and modern civilization teeters on the brink of collapse.
