The year is 2012 and it is, quite simply, the end of the world.
The apocalypse has begun, demons have begun to escape the confines of hell, digging their way up through the earth to emerge in South America, wave upon wave of the unholy creatures wrecking havok on the unsuspecting humans. The Horsemen of the Apocalypse and other powerful demons have begun to terrorise the world, killing as many people as possible.
Despair fills the hearts of all men in North America who would take up arms against the demons.
Famine has struck the countries of Europe, crippling them and their people.
Pestilance oozes it's way across Asia, either killing the people or turning them into zombie-like husks who's only desire is the feed.
War rages in Africa, the Horseman providing the region with as much devastation as he can.
Death creeps into Oceania, leaving the countries barren and empty of all life.
The apocalypse is going off without a hitch.
Except... it's early.
The apocalypse isn't supposed to happen for a number of years yet but here it is happening right now, way too early. The Creator, althought omni-present, isn't in contact with the angels at the moment and so they cannot ask for divine assistance or guidance. As the demons are moving in on Earth, staking their claim to it and the humans who live there, the angels have to moblise to fight them back, knowing that the world is not yet ready to end.
But with factions within the ranks of the angels potentially helping the demons and the rapidly dwindling numbers of humans, the angels will have to act fast to ensure that there's a world left to save. The demons will have to fend off the angels long enough to either enslave or kill the last of the humans. And the humans will just have to hold on for dear life as the armies of Heaven and Hell clash with the world as the price.
