Out of the surviving human population 3 factions formed.

The Governors
The Religious Cult
Civilian Surviors

The Governors; A band of soldiers lead by a fanatical Ex-General. Their aim is to restore a form of law and order to the cities; but in a way that we would call dictatorship.

A freak Religious cult that say they predicted this 'cleansing' of the earth all along; with new found faith in their religion they are more determined than ever that this was meant to be, and that they are the saviours and must finish the 'cleansing'.

The final faction... are ordinary people, a handful of innocent Civilians that got caught up in this mess, they are bewildered and angry at what happened to their families and everyone they knew, and are just trying to survive from day to day in this dark new world.
