Colt Express Bandit Pack introduces a new way to play the game, turning one character into a Bandit controlled by the game. As players compete to become the richest outlaw of the Old West, they now have to make sure the Bandit does not disrupt their plans.

The mini-expansion has players facing Ghost, the nefarious racketeer, who will go out of his way to retrieve a suitcase full of money. If Ghost still possesses the suitcase at the end of the game, he alone wins the game!
