The War raged globally for a decade, gradually sweeping away the old order and replacing it with anarchy. With a final crescendo, it reached its cataclysmic finale, and only now have the ashes settled enough for the survivors to emerge from their underground bunkers once again.
In the aftermath a new age for humanity has begun. The world is a broken hellish version of its former self. By day the sun is visible as a faint ghost through the pall, a memory of golden promise. Rain spits black torrents from the heavens. Stagnant rivers reflect the hazy sheen in an inverted pall. Black trees morph and twist out of the hellish bracken.
No matter though, the bunkers are still operational. While scavengers forage the ruins of civilisation for anything that might ensure another day of survival, mechanised factories continue to provide sufficient material to ensure death at high velocities. There isn't much left, but it is worth fighting for...
The War may be over, but the Battle has only just begun. It is Year 0.
