• Anemone HillsThe Anemone Hills are Subnautica 2's biome of towering pink-and-green anemones about 300 m northwest of the Lifepod, 0 to 151 m deep, where the infected Heat Tolerance Angel Comb waits behind Bloom you clear with the Sonic Resonator.
• Coral GardensCoral Gardens and North Coral Gardens are Unknown Worlds' names for Subnautica 2's early coral areas around the Lifepod; update 1.1 (Jul 8, 2026) put a second Biolab and more Silver there, and 1.2 gave North Coral Gardens its own music.
• Dolerite SpiresThe Dolerite Spires are a maze of jagged volcanic pillars in Subnautica 2's starting region, shallow to mid depth, with Lithium and Titanium, Quaker's Meetinghouse and two Spires wrecks that All Things How lists for the High Capacity Air Tank and the Rebreather on the launch build.
• GraveyardThe Graveyard is Subnautica 2's hot, orange-watered biome, 0 to 266 m deep, that needs the Heat Tolerance Adaptation; it holds Gold, Salt, Sulfur and Lithium, the Tadpole Pens, Tailings Village, a Cicada Wreck, Nahema's Lab and hundreds of Water Slugs.
• Metal FarmsThe Axum Metal Farms are the far eastern edge of Subnautica 2's Early Access map, about 2,000 to 2,200 m east-northeast of the Lifepod beside the Karakorum Power Plant, the only source of Troilite and Atacamite and where you find the Axum Bacterial Culture to build a Metal Farm of your own.
• Necrolei HillsThe Necrolei Hills are Subnautica 2's infected hills about 300 m northwest of the Lifepod, the main source of Necrolei Cysts for Strong Acid, with Copper, Titanium, Deepwing Egg Clumps and fauna mutated by the Bloom.
• Observatory IslandObservatory Island is Subnautica 2's Axum tower rising out of the sea about 1,000 to 1,200 m east of the Lifepod, with the Alien Ruins (Unknown Worlds' Axum Ruins), the Rosetta Stone, a Biolab since 1.1 and the Axum Observatory, where the Early Access story stops.
• PlateausThe Plateaus are Subnautica 2's rocky biome about 300 m northeast of the Lifepod, 23 to 119 m deep by All Things How's count, with Camp One, the Old Habitat and the caves that hold the early Silver; the sandy Lead Zone lies nearby.
• Root CanyonRoot Canyon is Subnautica 2's deepest explorable biome, a pitch-black canyon 365 to 750 m deep in the far east, with root-like walls, the Control Room, Tech Sites, Blight Nodes, a Cold Zone, colonist Dive Elevators and the Axum Metal Farms; the Collector Leviathan patrols its lower reaches.
• ShallowsThe Shallows are Subnautica 2's starting biome, the bright coral reefs around the Lifepod, 3 to 224 m deep by All Things How's count, with the Welcome Center about 85 m southeast, the first Angel Comb, Quartz-filled Coral Domes and caves of Copper and Titanium below.
• Tar CascadesThe Tar Cascades, in the area Unknown Worlds calls the Sparse Plains, are Subnautica 2's dark, tar-coated crossing about 700 m east of the Lifepod, 0 to 250 m deep, where the Collector Leviathan guards the way to the Axum ruins; cross low along the bottom in a Tadpole.
• Tufa ZoneThe Tufa Zone, which guides call Tufa Towers, is the biome of tall rock towers about 400 m south of Subnautica 2's Lifepod, home of the Great Jaw clam and its Lithium; it and the Thermal Area got their own music in update 1.2 (Aug 19, 2026).
