"In the western areas of Mars, where men are men and the horses love them for that, is the setting for our tale of power, control and a really nice peanut butter and jelly sandwich. This is where the land is untamed, the people are wild and lawlessness reigns. Do you have what it takes to make your mark on this dusty land and call yourself a true Martian Gunslinger?"
