Subnautica 2 Base Building Guide: Best Early and Late Game Locations and Blueprint Acquisition

Subnautica 2 base location selection, blueprint acquisition, hydroelectric turbine usage tips. Early game: build on flat ground near Escape Pod 105, use ocean currents for power. Late game: recommend Alien Ruins, abundant minerals and close to objectives. Detailed steps include construction gun, room blueprint, silver ore locations, etc.

• Guide Theme: Base Building

Prerequisites

• Scanner
• Battery
• Portable Locker
• Sea Litchi
• Fiber Grow Bed

Correction Notes

• 'Reception Center' might be a misrecognition of 'Outpost' or 'Tree of Life'; it's actually an early building.
• 'Camp One' might refer to the 'Escape Pod One' or 'Aurora Wreck' area.
• 'Biological Laboratory' might be 'Biological Research Facility'.
• 'Old Habitat' is a precise location name.

6

Collect Silver Ore and Build Initial Base

Mine silver ore in the cave next to Camp One; it is used to make oxygen tanks and power materials. After getting the Room Blueprint, return home to build a base and containers.

Key Points:

• Silver ore location: cave next to Camp One
• Silver ore uses: oxygen tanks, power generation

Choose Early Game Base Location

Time: 02:08.400 - 02:26.730

1 / 73

7

Choose Early Game Base Location

Build on flat ground near Escape Pod 105; there is a large ocean current nearby for hydroelectric power. Use solar power as a transition before unlocking hydroelectric turbines.

Key Points:

• Location: direction of Escape Pod 105
• Terrain: flat ground
• Power: ocean current hydroelectric (can place 20 turbines)

Acquire the Hydroelectric Turbine Blueprint

Time: 02:34.210 - 02:59.370

1 / 101

8

Acquire the Hydroelectric Turbine Blueprint

Bring a portable locker. From the escape pod, go north 360 meters to the Old Habitat; scan the first hydroelectric blueprint next to the water flow. Then go to the platform where the 'Welcome Home' sign points to 75 direction; scan the second hydroelectric blueprint along with power transmission and interior wall.

Key Points:

• Distance to Old Habitat: 360 meters north of escape pod
• Number of hydroelectric blueprints: 2
• Platform location: 'Welcome Home' sign pointing to 75 direction

Unlock Other Important Blueprints

Time: 03:01.530 - 03:09.370

1 / 31

9

Unlock Other Important Blueprints

Inside the Old Habitat, scan the blueprint for the Battery Charger, Processor, and Sonic Resonator.

Key Points:

• Inside Old Habitat
• Blueprints: Battery Charger, Processor, Sonic Resonator

Build Hydroelectric Turbines and Connect Power

Time: 03:09.850 - 03:30.380

1 / 82

10

Build Hydroelectric Turbines and Connect Power

Return home and build hydroelectric turbines. Note that the power transmission connection must use a circular base, otherwise it won't supply power. It can be connected to the roof or side.

Key Points:

• Power transmission requirement: circular base
• Connection method: roof or side

Collect Copper and Titanium

Time: 03:30.700 - 03:37.420

11

Collect Copper and Titanium

The cave next to the early-game base location contains copper and titanium, making them easy to collect quickly.

Key Points:

• Copper and titanium location: cave next to base

Summary of Early-Game Base Advantages

Time: 03:37.780 - 03:46.540

Choose Late-Game Base Location

Time: 03:47.380 - 04:27.080

1 / 159

13

Choose Late-Game Base Location

It is recommended to build a second base next to the marked dwelling at the Alien Ruins. Reasons: close to late-game objectives (2400 meters from escape pod), abundant minerals (all ores except lithium), and availability of hydroelectric and thermal power.

Key Points:

• Location: next to marked dwelling at Alien Ruins
• Approximately 2400 meters from escape pod
• Minerals: all ores except lithium
• Power: hydroelectric + thermal

Solving Food and Water

Time: 04:27.760 - 05:07.530

14

Solving Food and Water

When building at Alien Ruins, bring Sea Litchi and four Water Jellies. Initially, catch fish near the tower and quickly build a grow bed. Use the Sea Stars on the roof to grow fiber, make oily salad, or use fiber in the processor to produce water. You can also mass-breed Sea Litchi to solve food and water.

Key Points:

• Sea Litchi
• Grow bed
• Fiber source: roof Sea Stars
• Oily salad
• Fiber to water

Finding Silver Ore Location

Time: 05:07.810 - 05:36.090

15

Finding Silver Ore Location

From the grow bed, head in the 330 direction. After seeing a water flow, dive down to below the red plants to collect large amounts of silver ore.

Key Points:

• Direction: from grow bed head 330
• Markers: water flow, red plants
• Depth: dive below red plants

Use Alternative Materials for Acid

Time: 05:38.520 - 05:49.360

Use Alternative Materials for Acid

If you didn't bring any Dead Floater Jellyfish, you can use gold and sulfur instead to make acid. Gold and sulfur can be collected from the volcano beneath your feet.

Key Points:

• Alternative materials: gold + sulfur
• Location: volcano beneath your feet
