Fantasy Flight Games is bringing the world of tunnel fighting to the world of Dust in their Operation Hades expansion. Here’s a preview look at what they’ve got in store.
From the preview:
Operation “Hades” introduces new rules for underground fighting, as well as two new kinds of tiles, each of which comes with their own, specialized terrain rules. When fighting underground, forces have to deal with rules for dim lighting, low ceilings, and limited deployment.
