Sophie’s Seclusion

After leaving the Old Habitat, enter the cave beside the “Welcome Home” sign. The cave has blue guiding lights.

After the second blue light, go down, turn 180 degrees. Spot a hatch at the bottom. There’s plenty of Silver on the nearby rock walls.

Crafting & Building

Return to base and craft the Underwater Propeller at the Fabricator. Use the Habitat Builder to build:

  • Processor
  • Battery Terminal — charges batteries when base has surplus power; pair with Hydroelectric Turbine
  • Bio Bed — set respawn point in your base
  • NoA Terminal — mission terminal for your base

How to Use the Processor

The Processor makes advanced materials (like Titanium Ingot) in a powered base:

  1. Click “Configure Processor” on the left, select a recipe (e.g., Titanium Ingot)
  2. Click “Load Processor” — Titanium Ingot needs 3 Titanium per use, click once to load 3
  3. After the countdown finishes, click “Open Processor Output”
  4. Drag the finished product to your inventory
