Real ocean science. Fantastical depths.
Learn by building a world.
Fathom Atlantis is a simulation where you design and manage an underwater civilization — but every system you interact with is grounded in real ocean biology, chemistry, and ecology. Food webs behave like food webs. Biomineralization is how you build. Species presence is mapped through eDNA.
The fantastical city is the frame. The science is the substance. You learn it by needing it.
We're building this carefully, in the open, with researchers and educators from the start.
Every system in Fathom Atlantis is built on real science. These are the three domains your civilization will draw from: engineering the deep, growing with living materials, and learning to read what the ocean is telling you.
Underwater structures don't fight the ocean. They negotiate with it. Pressure, current, and tidal energy become constraints you design around, and eventually, resources you harness. Real ocean engineering principles govern every structure you place.
Coral builds with dissolved minerals. Kelp forests feed entire ecosystems from sunlight and current. In Fathom Atlantis, living organisms aren't decoration. They're infrastructure. Biomaterials, synthetic biology, and regenerative aquaculture are how your civilization grows.
Most of what happens in the ocean is invisible: chemistry shifting, eDNA drifting, populations rising and falling in silence. Learning to sense, measure, and interpret those signals is how you understand what you've built and what's at risk.
Fathom Atlantis is in active early development. No release date yet, no promises. We're building it carefully, with real scientific grounding, and we want the right people following along from the start.

We're particularly interested in hearing from marine biologists, science educators, and people who've tried to explain eDNA at a dinner party.
