This would be mine apocalypse
In the year 2010 the Earth met her deadliest nemesis, an unexpected invasion of the Supernatural. Unprepared, the armies of the world couldn’t stand against foes immune to human made weapons. Not able to bring this evil on its knees, they even used nuclear weapons, but it only brought disaster on their self. Now with their modern technology and weapons destroyed, the people on Earth were thrown back to the Dark Ages, with demon Lords who demanded tributes, and hordes of undead walking the face of the Earth. Even in the darkest hours, heroes emerged and battles are won against the evil that has invaded the Earth.
