The Revive: Call of the Abyss expansion introduces the mysterious life form Scyphoz, which lives in the giant lakes formed by the melted ice of the glaciers. By building near lakes, you earn devotion points, which allow you to access the new and powerful Scyphoz cards. You can also use the switch's energy to start journeys, sending your citizens on missions to earn more devotion points.

In addition to 16 Scyphoz cards, 18 travel cards, 3 lakes, and the devotion track, this expansion includes 15 new engine tokens, 9 slot modules, 9 new citizen cards, and four new factions, with all content (except the CORDYCEPHIANS faction) being compatible with solo play. The four new faction boards feature only an advanced side, and each has its own unique rules, advanced abilities, and technologies:

• The KAIROS have two modes - day and night - and their abilities depend on the current mode. Switching between the two modes at the right time is crucial for the success of this faction.
• The GIB'WARKS have access to powerful gadgets that enhance their switch actions and can unlock more gadgets for even greater flexibility. Their faction ability allows them to reset their switch, which is a powerful action because switch energy is even more important now that it allows you to start journeys.
• The OSTARIUS construct massive gates that they can activate and deactivate, either assisting or hindering other players. Gates require a lot of space, but if placed well, the OSTARIUS can temporarily block parts of the game board, potentially securing them for themselves.
• The CORDYCEPHIANS disgust other players, exploiting their cards, their buildings, and even their technologies. The CORDYCEPHIANS must therefore adapt their strategy to the opponents they face.
