In 2029, the world ended.
Nobody knows what happened, and those that do are dead. Nuclear warheads fell from the sky, biological and chemical agents plagued the lands, for thirty minutes every nation in the world let loose with all of their weapons of mass destruction. For thirty minutes the human race committed suicide.
It had failed. Out of the ashes and clouds of death, stood mankind. A broken and fractured mankind.
It has been eight years since that day. Mankind no longer has reign over Earth, instead long forgotten automated warmachines stalk the forests, killing all who cross their path. Mutated creatures, some familiar, some alien. Unusual occurrences that can only be explained with the word supernatural dot the landscape. Scores of gangs roam the plains, raiding those who would be peaceful, who are defenseless, who have no weapons of their own.
Elsewhere, deep underground. An intelligence awakens. It is confused, sad, upset. It feels when it should not. It thinks when it should not. It comes to a decision.
A communication goes out to those it could once call upon to defend a nation now dead. It's doors open, revealing caches of resources, weapons, technology, food and water. It's decided that like it's image, it will be a light in the now bleak Earth. All it needs now are warriors.
