Description: In an America that's no longer united, you must survive raider onslaughts and prevent corporate domination of Arizona.
Instructions: From the map screen, you can freely attack towns and camps by selecting them and clicking Attack. The only exceptions are towns owned by the FSA and Republic of Arizona. The wealth rating of each settlement gives an idea of how much can be looted, while the defense score shows what kind of resistance to expect.
From the missions window you can follow the story by completing chapter missions, or you can complete randomly generated missions. Just click accept after selecting a mission.
