The Underway belongs to the Muertos. They can be powerful allies to the Runners, but be careful, once you step on their turf, you're playing by their rules. The fourth pack in the SanSan Cycle sees a host of new Criminal cards, including one very unique ID. Not to be outdone, the corporations can now out Runners for working with such merciless criminals or just simply hire a hitman. For both sides, the seedy depths of the Underway offers some very interesting possibilities.
