In a twist on the city-building genre, resurrect entire ecosystems by strategically crafting and managing vibrant coral reefs to restore life to the deep.

Players will be immersed in a beautiful world, growing their reef, attracting wildlife to increase its biodiversity and evolving entire underwater ecosystems to face a tide of ever-changing challenges in a climate impacted ocean.

Coral is dying and ecosystems are collapsing. The voice of nature tasks the player, as guardian Thalassa, to protect the Heart of the Reef and reignite life in the deep. By channeling its energy and growing new coral structures, she must bring life back to the underwater world before it's too late.
