Why Power Comes Before Expansion
A bigger base is only useful if it stays powered. Before adding storage, crafting stations, or vehicle support, make sure your power system can handle regular use.
Power Transmitters matter when your energy source is not directly beside the base or when you want to organize a safer layout.
Planning A Power Setup
Decide what the base needs to run: crafting, charging, scanning, storage, and vehicle prep. Then build power capacity with room for future upgrades.
Route Connection
Power problems often show up right before long resource runs. Fix the base first so returning from a difficult route does not become another emergency.
How To Use This Page
Use this page when a location, base system, code, or exploration route is blocking progress. These pages should clarify what belongs to Subnautica 2, what belongs to older games, and what preparation the route needs.
Use current in-game landmarks and official updates; legacy franchise wikis are useful only for older-game clarification.
Before You Act On This Guide
- Confirm the location belongs to Subnautica 2, not an older Subnautica game.
- Bring supplies for the return route, not only the destination.
- Separate scouting from farming or code hunting.
- Mark useful landmarks before entering a long structure or objective loop.
Stop following a guide if its location names, vehicles, or codes clearly belong to another Subnautica title.
