The Revive: Call of the Abyss expansion introduces the mysterious life form Scyphoz, which lives in the giant lakes that are formed by meltwater from the glaciers. By building near lakes, you gain devotion points, which let you access the new and powerful Scyphoz cards. You can also use the switch action to initiate journeys, sending out your citizen on missions to gain more devotion points.
Aside from 16 Scyphoz cards, 18 journey cards, 3 lakes, and the devotion track, this expansion contains 15 new machine tokens, 9 slot modules, 9 new citizen cards, and four new tribes, with all of the content (other then the Cordycephians tribe) being compatible with solo play. The four new tribe boards feature only an advanced side, and each has its own unique rules, advanced abilities, and technologies.
