The greatest cover-up in history is about to be unearthed.

With famine and disease spreading out of control, the death toll was the worst in recorded history. It was being described at first as the Black Death. Little did the world know at the time but it was much worse.

The living had to fight to stay alive. It was what they fought against that the world wasn't ready for. Corpses rose from out of the ground, rotted and putrid. Decaying masses herded quickly, devouring everything in their way.

It is now 1855 and a crew of fearless cowboys face off against what their ancestors failed to vanquish. Follow Gus, Cole, Hector, Fred, and Yahto as they do everything they can to eradicate the pestilence plaguing the Wild West.

To right the wrongs of their forefathers, they must purge the world of the undead.

Man took back what was rightfully theirs. Or did they?
