Terrorist have invaded America. They have attacked with dirty bombs as well as some nukes. They have infiltrated our lives with their terrorist in a vast force that started at the east coast and moved west until they were stopped by us at the Rocky Mountain's. They met a force of people that they could not conqure and have begun to pay the price of there intrusion of America. The people that were prepared for this possibility now have to make it to a safe zone known as "The Fortress." A sanctuary for the many to reverse the tides of terror of this holy war. And the payback they get unleashed on them from the likes of people they could not imagine in their wildest dreams.
