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

In addition to 16 Scyphoz cards, 18 journey cards, 3 lakes, and the loyalty track, this expansion contains 15 new engine tokens, 9 slot modules, 9 new citizen cards, and four new tribes, with all content (except for 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:

• 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 tribe.
• The GIB'WARKS have access to powerful gadgets that enhance the switch actions and can unlock more gadgets for even greater flexibility. The tribe's ability allows them to reset their switch, which is a powerful action because the switch energy is even more important now that it allows you to start journeys.
• The OSTARIUS build massive gates that they can activate and deactivate, either helping or hindering other players. The 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 leech off other players, exploiting their cards, buildings, and even their technologies. The CORDYCEPHIANS must therefore adapt their strategy to the opponents they face.
