You take on the role of the Desert Ranger, who fights in a lost battle to keep his beloved Arizona alive, when the self-proclaimed Patriarch of Colorado sends a radio message and promises him help if he completes a job that only a stranger can do - to save his family 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 snow-moving vehicle, training new fighters, and fighting in the hostile wasteland - while trying to decide who to trust in a place plagued by corruption, intrigue, warring factions, crazy heretics, criminal gangs, and bitter feuds between families. You're not even sure if you can trust the Patriarch, but since he holds the survival of Arizona in his hands, can you do otherwise?
