On the 11th of July, 1899 at 10 a.m., the Union Pacific Express has left Folsom, New Mexico, with forty-seven passengers on board. After a few minutes, gunfire and hurrying footsteps on the roof can be heard. Heavily-armed bandits have come to rob honest citizens of their wallets and jewels. Will they succeed in stealing the suitcase holding the Nice Valley Coal Company's weekly pay, despite it having been placed under the supervision of Marshal Samuel Ford? Will these bandits hinder one another more than the Marshal since only the richest one of them can come out on top?
In Colt Express, you play a bandit robbing a train at the same time as other bandits, and your goal is to become the richest outlaw of the Old West. The game consists of five rounds, and each round has two phases. The game takes place in a 3D train in which the bandits can move from one car to another, run on the roof, punch the other bandits, shoot them, rob the passengers, or draw the Marshal out of position. The train has as many cars as the number of players, and each car is seeded with gems, bags of loot or suitcases at the start of play. Will you be the richest bandit in the outlaw gang?
