In Colt Express, you play a desperado among several who attack a train. The Marshal patrols the train, thwarting the plans of the bandits. Who will become the best gunslinger? Who will get the greatest share of the loot?

Each character has his own personality but, at the end of the day, they all have the same goal: to get the biggest slice of the pie in robbing the passengers.

A game goes in 5 rounds. Each round, there are 2 steps: programming the next actions by placing card on the top of the common pile; performing those actions.

The possible actions are: moving from a car to another one; going up or down; robbing the loot; shooting an opponent; punching an opponent and making him loose a loot; moving the Marshal. When he meets a bandit, the latter flees to the roof and receives a shot.

At the end of the game, the richest outlaw wins the game.
