Wild West Z is the story of the Wild West, enslaved by a supernatural force and its monsters. Take part in gang warfare and battles with monsters on American soil.

1896. Louisiana is ravaged by a newly appeared unknown force, dubbed the Origin, which has emerged from the bowels of the earth and created monsters that destroy people and devour their souls. The U.S. Army is unable to counter and retreats, leaving total chaos in the state. Most of the residents were either killed or fled, but some were able to band together to take control of the situation. The territories are divided between them and each wants to establish their own orders, but not everyone wants to play fair and try to master Origin and use its power to establish a dominant position in the world of rifles and revolvers. We, on the other hand, are a member of one of the gangs, destined to deal with this and find out what Origin can do in human hands.
