You crash-land on a planet that's entirely ocean. Your life pod floats above coral reefs, kelp forests, and volcanic trenches—all filled with alien sea life, some docile, most dangerous. Survival means managing oxygen, crafting gear from scavenged materials, and building submersibles to reach deeper biomes where rarer resources unlock better equipment. You'll construct underwater bases, scan creatures for data, and navigate bioluminescent caves while avoiding predators. The loop: explore shallow zones for basics, push into riskier depths for upgrades, repeat. No combat focus—stealth and evasion matter more than firepower. Progression gates tie directly to how deep you're willing to dive. It's tense, methodical exploration with base-building on the side.
