Subnautica: Below Zero Save File Location

Last verified: 2026-10-08

Save file location (Windows (Steam)): Steam\steamapps\common\SubnauticaZero\SNAppData\SavedGames

Quick answer: On PC, Subnautica: Below Zero stores saves inside the install folder at ...\SubnauticaZero\SNAppData\SavedGames\ , one folder per save named slot0000, slot0001, and so on. On a standard Steam install that is C:\Program Files (x86)\Steam\steamapps\common\SubnauticaZero\SNAppData\SavedGames . Unknown Worlds officially DISABLED Steam Cloud for Below Zero, so there is no cloud backup — copy a slot folder out before updating, verifying files, or reinstalling, because those can wipe the install folder.
Windows (Steam)
Steam\steamapps\common\SubnauticaZero\SNAppData\SavedGames
Windows (Epic / other)
<install folder>\SubnauticaZero\SNAppData\SavedGames

Below Zero is one of the few games where Steam Cloud is officially switched off — the developers disabled it — so your saves live only inside the install folder and a manual backup is the ONLY backup. Here is the exact PC path and how to protect your run.

Save file locations

Windows (Steam)
Steam\steamapps\common\SubnauticaZero\SNAppData\SavedGames

Full default: C:\Program Files (x86)\Steam\steamapps\common\SubnauticaZero\SNAppData\SavedGames\ . Each save is a slot00XX folder. Quick route: right-click the game > Manage > Browse local files, then open SNAppData\SavedGames.

Windows (Epic / other)
<install folder>\SubnauticaZero\SNAppData\SavedGames

Same SNAppData\SavedGames layout inside wherever the game is installed. Note the folder is 'SubnauticaZero', separate from base Subnautica.

Cloud saves

Subnautica: Below Zero does NOT use Steam Cloud — Unknown Worlds deliberately disabled it because cloud syncing was corrupting saves. That means there is no automatic backup at all: your only safety net is copying a slot folder out of SNAppData\SavedGames yourself, especially before an update, a Verify Integrity, or a reinstall.

Cloud save conflict & platform recovery

Real risk: because saves sit in the install folder and there is no cloud, an update, Verify Integrity, or reinstall can delete a run with no cloud copy to restore from.

  1. With the game closed, copy your slot00XX folder from SNAppData\SavedGames somewhere outside the install folder.
  2. Before any update, file verification, or reinstall, make that copy first — there is no Steam Cloud to fall back on.
  3. To restore, paste the slot folder back into SNAppData\SavedGames with the game closed; it reappears in the in-game load list.
