Subnautica 2 Biomes
Subnautica 2 biomes organized for starter routes, resource regions, hazards, reported coordinates and spoiler-safe map planning.
Quick answer
Subnautica 2 biomes are best handled as route regions: each biome can affect resources, depth, danger level, POIs and story routing. Because Early Access changes over time, this page labels whether biome notes are site-reviewed, third-party reported or route-only.
Subnautica 2 biome overview
This page is the biome hub for the Subnautica 2 map. It separates starter areas, resource-heavy regions, hazard zones and reported coordinate areas so players can decide where to explore before opening the full interactive map.
Biome names and boundaries can change during Early Access. Exact-looking coordinates stay tied to their source, while broad areas are written as route guidance instead of fake borders.
Early safe areas
Starting Shallows, Coral Gardens, Stone Pillars
Resource routes
Axum Ruins, Overgrown Ruins, Sparse Plains
Hazard checks
Collector arena, deep-start reports, wreck routes

Starter & Safe Routes
Early areas and forgiving routes for first tools, scanner setup and short resource loops.
Major starter-region reef with the densest normalized point coverage.
Dangers
starter oxygen mistakesreef ambush pocketsfauna crowding
Route hint: Start with shallow coral routes, then use related resource pages before committing to deeper reef pockets.
Early human-structure biome with shallow access and compact resource density.
Dangers
interior oxygen risktight sightlinesmoderate fauna pressure
Route hint: Approach from shallow water, mark the exit and work outward from the structure instead of improvising deeper turns.
Early terrain transition with more vertical cover and moderate route risk.
Dangers
Navigation loss around pillarsmoderate fauna risk
Route hint: Use as a route landmark, not an exact point.
Early human/colony route landmark tied to cave systems and Silver routes.
Dangers
Cave oxygen riskroute commitment
Route hint: Use cave systems and geothermal outskirts for early Silver planning.
Early landmark connected to the northern trench resource route.
Dangers
Current navigationcave oxygen risk
Route hint: Go north roughly 350-400m toward the reported water-current trench for mixed resources.
Resource Biomes
Resource-dense regions to use after basic oxygen, navigation and return-path planning are stable.
Large ruin field with dense research coverage and many resource groups.

Dangers

Route hint: Use the research centroid and depth range as a broad planning signal, then submit capture evidence before plotting exact boundaries.
Ruins-and-growth biome with rich fauna coverage and deep route pressure.
Dangers

Route hint: Work the outer growth first, then move inward only when the exit direction is still obvious.
Open, thinly covered biome where exposure matters more than clutter.
Dangers
open-water exposurelong return pathslimited cover
Route hint: Cross in short legs, confirm the return bearing often and avoid turning broad research density into fake exact markers.
Hazard / Spoiler Biomes
High-risk or spoiler-sensitive areas where survival planning matters more than fast farming.
Tiny high-risk arena sample tied to a single leviathan encounter.

Frequently asked
How many biomes are in Subnautica 2?
This tracker currently organizes 22 biome and area entries. Some are normalized research biomes, some are community route areas, and some are reported coordinate regions, so the count should not be treated as an official full biome total.
What are the main Subnautica 2 biomes for early players?
Starting Shallows, Coral Gardens, Stone Pillars, Camp One and Old Habitat are the first areas most useful for starter routing, basic tools and short resource loops.
Are Subnautica 2 biomes randomly generated?
No public official source says Subnautica 2 uses randomly generated biomes. This site treats biome names, coordinates and boundaries as evidence-based map data instead of procedural assumptions.
Which biome should a new player use first?
Start with Starting Shallows and Coral Gardens, then move through Colonist Bunker, Camp One or Old Habitat once oxygen and return routes feel stable.
Which biome has Silver?
Silver appears in early route planning around Coral Gardens, Colonist Bunker and Plateau-style reports. Use the Silver page for current map filters and evidence labels.
Are biome coordinates verified?
Only entries labeled with reviewed evidence should be treated as verified. Broad areas and coordinate regions are useful map filters, not guaranteed boundaries.
What does an approximate area mean on this index?
It means the page is useful for route planning, but you should treat the map link as a broad filter rather than a guaranteed boundary.
Can I submit biome boundaries?
Yes. Submit coordinates, screenshot or video evidence, game build and notes through the Submit page.
