Where Are Subnautica: Below Zero Saves Located?
Below Zero Unity LocalLow folder with Unknown Worlds slot saves on PC.
Last updated
Below Zero follows the original Subnautica with saves in LocalLow under Unknown Worlds, one numbered slot folder per run. Each slot bundles the world, bases, vehicles and inventory together.
Slots are folders rather than files, so copy whole slot directories. The two games use parallel folders, never a shared one.
Where Subnautica: Below Zero stores this, by platform
%USERPROFILE%\AppData\LocalLow\Unknown Worlds\Subnautica Below Zero
Runs are slot0000 style folders inside with world and player data within. Copy the full game folder with the game closed. The original Subnautica uses a sibling Subnautica folder, so label backups to avoid mixing them.
Frequently asked questions
How do I back up Below Zero runs?
Copy the entire Subnautica Below Zero folder from LocalLow\Unknown Worlds. Each slot folder is one run and restores independently.
Can I move a Below Zero save to another PC?
Yes. Paste the slot folder into the same path on the new install with the game closed. Match game versions or the world may fail to load.
