Saboteur 2 is an expansion for Frederic Moyersoen's Saboteur, which first appeared in 2004.
The original Saboteur allowed 3-10 players, while Saboteur 2 handles 2-12 players. Saboteur 2 includes additional role cards (the boss, profiteers, geologists), new action cards (steal gold, change your role), and new tunnel cards featuring doors, ladders and bridges. What's more, the gold seekers can now be divided into teams -- blue vs. green -- and only those on the team that finds the gold score anything, assuming they do of course...
*NOTE* This is not a complete game, Saboteur is needed for play.
