Subnautica 2 Storage Guide — How to Get More Storage

How to Get More Storage

Collect Portable Lockers Early

Portable Lockers scattered in Coral Reefs

Before unlocking Habitat Builder, find Portable Lockers in Coral Reefs. Pick them up and place near your Lifepod.

Build Storage in Your Base

Wall Lockers and Floor Lockers for long-term storage

Stack Wall Lockers

Stack two Wall Lockers vertically — 40 slots total

Wall Lockers take minimal space. Stack two vertically for 40 Storage Slots in same footprint (vs Floor Locker’s 30).

The Bottom Line: This is the kind of mechanic that seems obvious after you know it, but the game sure as hell won’t tell you upfront. I learned most of this the hard way — by drowning, starving, or getting eaten. The systems in Subnautica 2 are deep but fair. Once you understand how they work, survival stops being a struggle and starts being a strategy. And that’s when the real fun begins.
