Fathomless

Retro Sci-Fi in the Deep Set in a grounded, retro-futuristic, Jules Verne-inspired world where Earth’s surface is uninhabitable. You must survive in the unexplored ocean, which hides increasingly strange truths the deeper you descend. A Colony in Motion Build and maintain a fully nomadic underwater settlement that must continuously relocate to survive shifting environments and resource depletion. Going Ever Deeper Resources are finite, and your survival depends on venturing ever deeper. Advancement comes from discovering hostile deep-sea biomes, strange fauna and flora, and rare minerals. Illuminating the Darkness The endless abyss is hostile and uninhabitable without light. You must illuminate your surroundings to build structures and gather resources — or risk being lost to the void. Fragile Lives Each colonist has unique traits, skills, relationships, and behaviors. Their lives matter — injuries are crippling, and death is permanent. They are not just tools; they are survivors thrown into this world alongside you. You need them, and they need you. Architecture Under Pressure Design and connect pressurized habitats, research stations, and living spaces that support your colony as it moves through the ocean. Optimize layout and logistics to make the most of your claustrophobic settlement. Adaptation is Survival Enhance colonists with mechanical upgrades or chimeric deep-sea bio-adaptations, altering their capabilities, roles, and chances of survival. But do so with care — or risk what it means to remain human. Signals From the Deep Send out exploratory submarines to salvage wrecks, uncover mysteries, and investigate strange lost ruins hidden beneath the sea.
