Set sail across a chain of handcrafted islands, each with its own ruins, resources, and secrets to uncover. Chart new routes, gather what you need to build your home base, and unlock ancient Atlantean technology as you push farther into the world.

Swim through glowing trenches, overgrown ruins, and underwater caves in search of gems, ancient technology, and long-lost secrets. The deeper you go, the stranger—and more powerful—the discoveries become. Oxygen is limited, though, so don’t forget to come up for air!

Your seaside villa awaits! Build the island retreat of your dreams with paintable walls, tiled mosaic floors, charming furniture, and houseplants galore. Watch the sun set from your deck, and recover health in safety while the dangers of night creep across the sea.

Sun-loving plants power your advancement through the journey of Atlantis. Grow dozens of types of unusual plants for food and to condense into energy for your arsenal. Build a greenhouse, automate watering, mix fertilizer, and reap the rewards of your crops.

Start with scavenged blades and scrap-tier tools, then advance to Atlantean energy weapons that channel solar energy to take out the most fearsome bosses. Unlock new blueprints through combat and exploration, craft gear with rare resources, and power your weapons with mystical plant-grown solar fuel.

Battle corrupted creatures to reclaim the sunken civilization’s ancient power. Clear infested islands and activate ancient lighthouses to open fast travel routes. Each conquered island brings new resources, tougher enemies, and more opportunity to expand.

Face the adventure solo or with up to 3 friends in online co-op. Share a home base, divide tasks, and explore alone or together.
