This expansion includes new roles and action and corridor cards. As usual, there are the treasure-seeking dwarves, but they are now divided into green and a blue team. As always, they try to dig an underground passage to the treasure. But this time they are not the only ones. There is the chief, for instance, who wins when the prospectors win. The profiteer is altogether a separate one. He wins not only when the prospectors win, but also when the saboteurs win. The geologist, on the other hand, is not at all interested in the treasure. He searches the corridors for valuable crystals.
With this expansion, saboteur becomes even more hectic and exciting. Ideal card game for large groups of up to 12 players!
