What to Do First in Subnautica 2

Quick Answer

Your first loop should be Scanner, oxygen upgrades, quartz/copper/titanium collection, Habitat Builder scans at the Welcome Center, and a small base with a full Fabricator.

Requirements

  • Stay close enough to the Lifepod for oxygen recovery
  • Collect titanium, quartz, copper, and battery materials
  • Use spoiler mode before reading deeper route details

Step-by-Step Route

  1. Use the Lifepod as your oxygen and storage anchor.
  2. Collect quartz from coral domes and copper/titanium from nearby nodes.
  3. Craft the Scanner and Standard Air Tank.
  4. Scan Habitat Builder fragments at the Welcome Center southeast of the Lifepod.
  5. Build a minimal base near the Lifepod, then add your own Fabricator.

What It Unlocks

  • Scanner-led progression
  • Starter base
  • Full Fabricator
  • Safer resource loops

Common Mistakes

  • Swimming deep before increasing oxygen safety.
  • Skipping quartz, which blocks early tools.
  • Building far from the Lifepod before you have storage and power planned.
