If you want the short answer: build your first base in the Shallows, move serious operations toward Chuer Towers or Plateaus, then add compact outposts in the Lead Zone, Graveyard, and Observatory.

Do not judge a biome by looks. Judge it by how many trips it saves, how often it tries to kill you, and whether it gives you the resources you actually need.

Subnautica 2 Biome Ranking Criteria

A good base location needs four things:

Each biome is scored out of 40 points.

Best Subnautica 2 Biomes Ranked

Best Starter Base: Shallows

The Shallows are still the safest first base location in Subnautica 2. You get food, basic materials, clean routes, and very few real threats.

Why It Works

The Shallows give us exactly what early game needs:

• Titanium
• Copper
• Quartz
• Easy food fish
• Safe build space
• Fast access to nearby early biomes

The only real problem is silver. You will outgrow this place once upgrades and base modules start asking for better materials.

Build Strategy

Use the Shallows as your starter hub.

Build:

• Fabricator
• Storage wall
• Power source
• Food/water setup
• Scanner support if available

If you keep running out of silver, do not abandon the Shallows immediately. Add a small resource run toward the Plateaus.

Best use: First main base

Avoid building here if: You want mid-game resources without travel

Best All-Round Base: Chuer Towers

The Chuer Towers are the strongest overall base location. Safe enough to live in. Rich enough to matter. Central enough to save time.

Why It Works

This biome has:

• Good resource spread
• Access to lithium
• Manageable threats
• Strong route value
• Distinct landmarks for navigation

The Great Jaw is the main thing to respect. It is huge, but it is not the same problem as a roaming Leviathan. Stay away from its trigger zones and the biome is very manageable.

Build Strategy

Build here when your Shallows base starts feeling too basic.

Best setup:

• Scanner Room
• Large storage
• Battery charging
• Vehicle access
• Resource sorting lockers

If you want one serious mid-game base, choose Chuer Towers over Anemone Hills or South Raceway. It simply wastes less time.

Best use: Main mid-game base

Main weakness: Terrain and visuals may not suit every player

Best Early-Mid Upgrade: Plateaus

The Plateaus are not as safe as the Shallows, but they are much better for progression. This is where we start solving real crafting bottlenecks.

Why It Works

The Plateaus give access to:

• Silver
• Lead
• Copper
• Quartz
• Titanium

That means fewer painful early-game resource loops.

The downside is creature pressure. Nibbler Mangoes, Sand Spee juveniles, and border threats make this biome less relaxing.

Build Strategy

Build on the safer side near the Shallows. Do not place your main hatch near hostile borders.

Good layout:

• Compact main room
• Scanner coverage
• Resource lockers
• Fast exit route toward Shallows

If you are dying often here, your base is too exposed. Move it closer to the safe edge.

Best use: Second base or early-mid main hub

Main weakness: More predators than beginners expect

Best Resource Outpost: Lead Zone

The Lead Zone is simple: come here when you need lead. It is one of the most useful farming biomes in Subnautica 2.

Why It Works

You get:

• Heavy lead supply
• Other mid-tier resources
• Good access toward harder zones
• Practical outpost value

The problem is local harassment. Mango Nibblers are annoying, and the Marrow Breach near the wreck can punish lazy routes.

Build Strategy

Do not build next to the wreck. Build on a safer edge and farm inward.

Recommended outpost:

• Scanner Room
• Fabricator
• Storage
• Medkit backup
• Power cell/battery chargers

Result: faster lead farming, fewer long trips, less inventory waste.

Best use: Mining outpost

Main weakness: Wreck-side danger

Best High-Risk Outpost: Graveyard

The Graveyard is dangerous, but it earns its score. This biome has serious resources, wrecks, and story value.

Why It Works

The Graveyard can provide:

• Titanium
• Gold
• Sulfur
• Celestine
• Advanced materials
• Wreck access
• Story progression routes

The catch is obvious: heat, predators, and Marrow Breaches.

This is not a cozy base biome. It is a pit stop biome.

Build Strategy

Keep it small.

Build:

• One compact room
• Power
• Fabricator
• Storage
• Medkits
• Emergency food/water

Do not overbuild until you know the patrol routes.

If you are adapted for the heat and know how to move through the biome, a Graveyard outpost saves a massive amount of time.

Best use: Dangerous resource and story outpost

Main weakness: Low safety, constant pressure

Best Late-Game Base: Observatory

The Observatory is the best late-game living space. It is safer than most endgame biomes and packed with useful resources.

Why It Works

The Observatory offers:

• Strong late-game resources
• Low threat level
• Alien tech access
• Good staging position for final biomes

Its weakness is the route. You need to pass near the Collector Leviathan Arena, which makes early travel miserable.

Build Strategy

Once you can reach it safely, make it your late-game hub.

Build:

• Full crafting setup
• Deep storage
• Power infrastructure
• Vehicle support
• Emergency return supplies

If you are still constantly returning to early biomes, delay this base. If most of your work is now deep-zone exploration, build it.

Best use: Late-game main base

Main weakness: Bad access from early biomes

Decent but Flawed Biomes

These biomes can work, but they are not top picks.

North Raceway

The North Raceway scores well because of its access value.

Build here if you often move toward the Graveyard. Keep it small: storage, power, medkits, batteries.

Do not make it your main base unless you like constant route traffic and moderate predator pressure.

Anemone Hills

The Anemone Hills are safe but poorly placed.

It has resources and food, but the map position hurts it. You spend too much time traveling.

Build here only if you like the biome's look.

Power Plant

The Power Plant has good resources but bad living conditions.

Threats include Needler Mangoes and deeper-zone pressure. Useful as a small station. Bad as a home base.

Root Canyon

The Root Canyon has top-tier resources and terrible access.

The Collector Leviathan threat and depth make it inefficient for most players.

Build here only when you are geared, confident, and farming specific late-game materials.

Worst Subnautica 2 Biomes for Base Building

Some biomes are not challenging. They are just bad investments.

South Raceway

The South Raceway has fewer resources and less route value than the North Raceway. Use it as a pass-through zone, not a base site.

Blighted Coral

Problems:

• Infected biome
• Parasites
• Infected Marrow Breach
• Poor resources
• Bad location
• Zero practical value

Enter, finish your objective, leave.

Collector Leviathan Arena

This zone has almost no resources and one massive problem: the Collector Leviathan.

The only build worth considering is a protected transit route. As a base location, it is dead on arrival.

Best Base Plan by Game Stage

Use multiple bases. One giant base creates long trips and wasted inventory space.

Recommended Route

1. Start in the Shallows.

2. Expand toward the Plateaus for silver and lead.

3. Move your serious base to Chuer Towers.

4. Add a Lead Zone mining outpost.

5. Build a small Graveyard pit stop.

6. Set up your late-game hub in the Observatory.

This route cuts travel time hard. It also keeps dangerous biomes from becoming full-time chores.

Key Creature Threats for Base Planning

Creature behavior matters more than size. A huge passive creature is less annoying than a small predator camping your hatch.

Rule of thumb:

If a predator patrols your daily route, the base location is worse than the score suggests.

FAQ

What is the best biome for a starter base in Subnautica 2?

The Shallows. It is safe, central, easy to navigate, and stocked with basic materials. Its only major weakness is poor access to silver.

What is the best overall base location in Subnautica 2?

Chuer Towers. It has the best mix of safety, resources, accessibility, and long-term value. It is the strongest mid-game main base choice.

Should we build a base in the Graveyard?

Yes, but keep it compact. The Graveyard is dangerous, but its 10/10 resource value makes it worth using as a pit stop for wrecks, story routes, and advanced materials.

Is the Observatory worth building in?

Yes. The Observatory is one of the best late-game hubs. The only issue is access, since reaching it means dealing with routes near the Collector Leviathan Arena.

Which Subnautica 2 biomes should we avoid building in?

Avoid Blighted Coral and the Collector Leviathan Arena. Both have terrible safety, weak resources, and almost no practical base value.

Summary

The best Subnautica 2 base strategy is not one perfect base. It is a chain of smart bases.

Build like this:

• Shallows for your first safe hub
• Plateaus for early silver and lead access
• Chuer Towers for your main mid-game base
• Lead Zone for mining
• Graveyard for dangerous resource runs
• Observatory for late-game operations

Skip Blighted Coral, South Raceway, and the Collector Leviathan Arena unless you enjoy making survival harder for no reward.

Best practical pick: Chuer Towers.

Best first base: Shallows.

Best late-game base: Observatory.
