Colt Express Bandits Expansion - Django - Rules of Play says:
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 Django expansion, Django has a thing with dynamite. Don't come too close to him... At the beginning of each round, Django drops dynamite where he is located. Django has an explosion action that triggers all the dynamite in the train. Every bandit who is inside or on the roof of an exploding wagon is ejected. They give Django their Wanted token and must use their next action to board the train once again. Django wins the game if he succeeds in getting all the bandits' Wanted tokens.
