Alrighty!
He's the deal.
The World is ending. Mankind is ending his existance in war. Fighting between individual factions and even individuals has spread accross the surface of the planet. The political situation has become "Fight or Die." Many have banded together to try to survive the coming cataclysm. For far above, the Earth's Moon Luna is falling from orbit. There is no real reason to fight, but you are compelled to end your lives in war. You have those that would follow you to your imminent doom. You may or may not have wanted them to, but they did so anyway.
The Gravitational forces involved with the moon's decent have inexplicably split the earth. Cracks reaching to the mantle, that are the size of continents, the oceans either destroying cities or draining away. The planet is a lost cause, and theres no way off. All you can do is fight to be the last one standing when the end comes.
Be the last one on the Stage. That Stage is the charred remains of New York city, some parts partially submerged, some parts filled with molten rock rising from the center of the Earth, and the rest torn and broken by the conflicts of men.
