On the 11th of July, 1899 at 10 a.m., the Union Pacific Express has left Folsom, New Mexico, with 47 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.
