Wild West Exodus
Alternate universe tabletop games are a dime a dozen, but Wild West Exodus is the miniatures-based tabletop wargame you need to check out. Set in a dark Wild West, the world you play in is torn apart by the evil forces of the Enlightened. Take the frontier as your battleground and battle it out with armies of steampunk war machines, biomechanically enhanced warriors, monstrous creatures, and even ordinary soldiers.
The game supports 2 to 4 players and each fields an army that ranges in size from 6 to 40 highly detailed miniatures. Check out the photos here:
