The game follows a fictional storyline where you find yourself in the quarantine zone five years after the event.
Everything has changed in that time, and you find yourself in a very different Britain, on the wrong side of the quarantine wall. The area is run by the military and beset with factions, in-fighting, and a growing sense of fear.
It’s up you to unravel the mystery of what happened. Explore the countryside, villages, and settlements and meet odd people, wicked cults, rogue government agencies and others along the way.
