Colt Express Bandit Pack: Belle Expansion
Each one of the six Colt Express: Bandits expansions allows the players to compete against the game itself, which is operating under the rules of that particular expansion. A new story is told each time as every expansion creates a specific goal and new actions for the bandit played by the game. That bandit may win, and if that happens, all the players lose. Thus you need to work together against this "bot", while keeping in mind that in the end, there is only one winner — the richest bandit, of course.

In the Belle expansion, Belle is looking for jewels. She always moves towards the place where there are the most jewels. She has two specific actions:

Theft, which allows her to take one jewel for every bandit in her location.
Charm, which makes move all the bandits towards her location.

The Marshal also has a thing with Belle, so she can stay in the wagon where the Marshal is located.
