Subnautica 2 Walkthrough and Progression Guide
Quick Answer
Current Early Access progression is best handled as staged loops: oxygen and scanner, base and full Fabricator, Sonic Resonator mining, Rebreather/deeper ruins, Tadpole setup, then roadmap-dependent content.
Requirements
- Scanner
- Standard Air Tank or Air Bladders
- Habitat Builder
- Full Fabricator
- Patch notes checked
Step-by-Step Route
- Stabilize oxygen and scanner progression around the Lifepod.
- Unlock Habitat Builder at the Welcome Center and build a first base.
- Add a full Fabricator inside your base.
- Find lead and scan Sonic Resonator fragments so large ore and Bloom Biofilm routes open.
- Scan and craft the Rebreather before longer deep-water trips.
- Scan three Tadpole fragments, build the Moonpool and Vehicle Fabricator setup, then craft the Tadpole.
What It Unlocks
- Low-spoiler progression path
- Resource route order
- Vehicle preparation
- Patch recheck queue
Common Mistakes
- Reading full-spoiler route details when you only need the next requirement.
- Assuming a single complete walkthrough will stay stable through Early Access.
- Skipping source dates on route-critical pages.
