You take on the role of a Desert Ranger, fighting a losing battle to keep your beloved Arizona alive, when the self-proclaimed Patriarch of Colorado sends a radio message promising help if you complete a job that only an outsider can do – save his land from the ambitions of his three bloodthirsty children.

So you travel from the scorching deserts to the frozen mountains and start from scratch, building a new base, finding a vehicle that can move in the snow, training new fighters, and battling in the hostile wilderness – all while trying to decide whom to trust in a place plagued by corruption, intrigue, warring factions, mad cultists, criminal gangs, and bitter family feuds. You're not even sure you can trust the Patriarch, but since he holds the survival of Arizona in his hands, do you have a choice?
