All Confirmed Subnautica 2 Biomes (and Far Far West)

Subnautica 2 takes place on an entirely new alien planet located in the Ariadne Arm. You will not find the familiar Kelp Forests of 4546B here.

Here is a list of the officially confirmed biomes (as of the May 14, 2026 Early Access launch) that you will be exploring. For depth, threats and resources at-a-glance, see the interactive predicted map.

The Biomes

1. Start Zone The equivalent of the ‘Safe Shallows’. This is where your escape pod lands and where you will find basic survival resources like Titanium and Bladderfish. Read the first 24 hours guide.

2. Coral Gardens A vibrant, highly illuminated area featured prominently in the trailer. Expect lots of harvestable flora and small, passive fauna.

3. Jelly Plateaus A mid-depth zone characterized by massive, gelatinous mushroom-like structures. Likely a transition zone containing mid-tier ores.

4. Kelp Forest (New Variant) While the name is familiar, this is an entirely new ecosystem. The ‘kelp’ here is much denser and features aggressive ambush predators hiding in the foliage.

5. Overgrown Ruins A mysterious biome hinting at previous habitation. Expect to find Alterra tech fragments and potentially ancient alien artifacts here. It is guarded by mid-sized predators.

6. Sparse Plains A desolate, open sandy area. It seems safe at first glance, but the trailer’s terrifying ‘Bobbit Worm’ Leviathan is known to burrow beneath the sand here.

7. VepZone A deep, highly toxic or acidic biome. You will likely need specific vehicle depth modules or DNA Modifications to survive the ambient damage in this zone.

What about ‘Far Far West’?

If you have been searching for a biome called ‘Far Far West’, you might be confused — there is no biome called Far Far West in Subnautica 2.

‘Far Far West’ is actually the title of a completely separate co-op shooter video game that happens to be releasing on Steam around the same time as Subnautica 2, causing search result confusion. The Ariadne Arm planet has its own unique biome list above.

Biome Depth Cheat Sheet

The seven confirmed biomes cluster into three depth bands:

Depth Band	Biomes	What you need
Surface (0–80m)	Start Zone, Coral Gardens, Ice Shelf	Standard O2 Tank, Fins
Mid-depth (80–300m)	Kelp Forest, Jelly Plateaus, Overgrown Ruins	High-Capacity O2 Tank, Tadpole vehicle
Deep (300m+)	Sparse Plains, VepZone	Reinforced depth modules, DNA pressure adaptation

Plan your first 24 hours around the surface biomes — never venture below 80m on Day 1 unless the Quartermaster has already built a base anchor.

What We Don’t Know Yet

Unknown Worlds has been deliberately tight-lipped on a few biome categories that we expect to appear during the 2-3 year Early Access window:

• Endgame caves and trench biomes — leaked datamines hint at a Lost River-equivalent and a deeper Abyssal Trench, but none confirmed.
• Procedurally seeded variations — the trailer hints at a fixed map, but devs have not ruled out seeded biome rotations.
• Story-locked zones — at least two biomes appear to be gated behind major story beats and will only unlock for late-game players.

Our predicted interactive map plots all of these as low-confidence markers, color-coded by source. Markers shift from predicted to confirmed as live player data comes in starting D+1.

Why “Far Far West” Confusion Is So Persistent

If you have searched “Far Far West Subnautica 2” and landed here, the explanation is dirty SEO data — not a hidden biome. Three reasons the search collision happened:

1. Far Far West (the unrelated co-op shooter) shares a launch month with Subnautica 2, so Google’s autocomplete co-occurred them.
2. Several early Reddit threads jokingly captioned trailer screenshots with “this looks like Far Far West” — search engines indexed the phrase.
3. A handful of low-quality clickbait sites published “Far Far West biome reveal” articles based on these jokes, spreading the false rumor.

There is no Far Far West biome. The seven biomes listed above are the only ones confirmed for Early Access launch.

Biome FAQ

Are all 7 biomes available on Day 1? Yes — Unknown Worlds confirmed that all seven launch biomes are accessible at Early Access start, though some require specific gear depth ratings to enter safely.

Which biome should I explore first? Start Zone, then Coral Gardens. The trailer’s Kelp Forest is tempting but it has the highest Day 1 player death rate due to Stalkers and Bleeders.

Will more biomes be added during Early Access? Almost certainly. The dev team’s stated roadmap mentions “at least 3-4 additional biomes” before the 1.0 release, plus deeper-tier expansions of the existing seven.

Where is the safest base location? At Early Access launch, the predicted-safest spot is the boundary between Start Zone and Coral Gardens — ~40m depth, low predator density, all four early-game resources within scanning range. We will publish a dedicated “best base locations” guide post-launch as player data arrives.
