Subnautica 2 Biomes — Full List & Map

The starter biome and home of Lifepod. Bright, sunlit, packed with passive fauna and the foundational materials (Titanium, Silver, Quartz, Lucifer Rotsac). Danger 1/5 — the only major hazard is the Mimic Pylon hidden among genuine Feather Kelp.

Starter (first dive, first base candidate)

Mid-shallow biome northwest of Lifepod, characterized by anemone clusters and the Hecaton Tunic. Primary early-game source of Necrolei Cyst — the renewable input for Strong Acid recipes.

Starter / Early Necrolei Cyst farming for Strong Acid recipe

Corrupted mid-game biome west of the Shallows, entered via a plateau hole ~186 m from Lifepod. Bloom Cankers obstruct passage and require the Sonic Resonator to clear.

Mid (must visit to unlock Heat Tolerance)

Plateau-topology biome northeast of Shallows, dominated by Dragon's Scale Coral and Cherimoya Rotsac. The story-progression hub — Old Habitat clusters four colonist blackboxes here.

Early–Mid (story progression)

Spire-formation biome — possibly a sub-region of the broader Tufa Towers area. Wreck-dense: five POIs in a relatively small area.

Sparse-region biome — flat seabed with scattered mineral deposits. Home of the **second Collector Leviathan boss arena** (no respawn).

Orange-tinted hydrothermal-vent biome east of Shallows. The mid-to-late game power-resource zone — Gold, Sulfur, Lithium, and the bulk of the colony lore.

Mid–Endgame

Coral Gardens micro-biome — primary dedicated Silver source. Small footprint but the highest Silver concentration per m² in the early game.

Karakorum entry biome (Observatory Island) — the first deep-region zone past the Shallows tier. Holds four story anchors: Rosetta Stone, Axum Observatory, Alien Ruins, and Ruby's Blackbox.

Mid

Deep Karakorum endgame biome and the home of the Collector Leviathan boss arena.

Karakorum micro-biome at 226 m. **Source of Creature Enamel** — required for Enameled Glass and the Bioscanner.

Karakorum micro-biome at 0–450 m. Heat-source zone — dense vent clusters yielding Gold and Sulfur.

Deep Karakorum biome east of Observatory. The endgame's electric hazard zone — Surge Jelly, Electric Geordie, and Twin Sitaray all carry shock damage.

Endgame / story

Extreme-depth Karakorum biome east of Power Plant. The deepest commonly-explored area at 5/5 danger.

Endgame

Tower-formation biome southwest of Shallows. Home of the Great Jaw Leviathan — a clam-trap-style predator that ambushes from inside a shell.

Mid

Shallow-depth biome east of Shallows. Source of the eponymous Lead deposits — the Sonic Resonator's gating material.

Early — main Tadpole fragment site

Distinct from Anemone Hills despite the similar name. A second Necrolei Cyst source — useful redundancy for Strong Acid farming.

Surface biome east of Shallows. The Flashlight-blueprint biome — North Raceway Large Wreck is the canonical first wreck after Welcome Center.

Early

Surface biome southeast of North Raceway. Lighter on POIs than its northern counterpart but holds the Colonist Bunker (Nahema's Lamb) at 87 m.

Early

Map boundary 'red wall'. Entering spawns the **Shiver Leviathan** — a single-purpose enforcer that prevents straying outside the playable area.

Meta-listing of the seven Cicada Wreck fragments scattered across the map: Lander Garage (Leadzone, 18 m), Canteen (Tufa Towers, 85 m), Empty Hold (Graveyard, 53 m), EVA Prep (Karakorum, 64 m), Therapy Room (Root Canyon, 192 m), Stairway to Heaven (Karakorum east, 300 m), Unknown Wreck (582 m below Lifepod SW).
