# NotAlterra

|
|
|
**Subnautica 2 Save Manager**
|
|
|
|
NotAlterra is an unofficial tool for managing Subnautica 2 save files. It locates your save folders, backs up and restores `.sav` / `.bak` files, and lets you inspect the internal metadata of every save.

|
|
|
Not affiliated with Unknown Worlds Entertainment or KRAFTON.
|
|
|
|
|
|

- **Create / restore** full backups (only `savegame_*` files)
|
|
- **Manage** UE5 Config `.ini` files — backup, restore, delete

|
## How to Build
|
|
|
|
```bash
|
|
# Linux
|
|
cargo build --release
|
|
|
|
# Windows (from Linux with mingw-w64)
|
|
rustup target add x86_64-pc-windows-gnu
|
|
sudo apt install mingw-w64
|
|
cargo build --release --target x86_64-pc-windows-gnu
|
|
```
|
|
|
|
|
|
## How to Run
|
|
|
|
Download the pre-compiled executable for your platform from the [releases page](https://github.com/forkless/NotAlterra/releases).
|
|
|
|
### Linux
|
|
|
|
```bash
|
|
tar -xzf notalterra-v0.1.3-linux-amd64.tar.gz
|
|
chmod +x notalterra
|
|
./notalterra
|
|
```
|
|
|
|
### Windows
|
|
|
|
Extract the `.zip` archive and double-click `NotAlterra.exe`, or run from a terminal:
|
|
|
|
```powershell
|
|
Expand-Archive notalterra-v0.1.3-windows-x64.zip -DestinationPath .
|
|
.\NotAlterra.exe
|
|
```
|
|
|
|
You can also extract the `.zip` using Windows Explorer (right-click →
|
|
**Extract All**), then open **Command Prompt** or **PowerShell** in that
|
|
folder and run `.\NotAlterra.exe`.
|
|
|
|
> [!IMPORTANT]
|
|
> **Running an unsigned executable on Windows** triggers a UAC "Unknown
|
|
> Publisher" warning, forcing you to click "Run anyway" and bypass
|
|
> Windows' safety net. This tool lacks a signature not because it's
|
|
> unsafe, but because services like SignPath Foundation require a
|
|
> well-established CI/CD pipeline, audit trail, provenance
|
|
> documentation, and community standing to meet their acceptance
|
|
> criteria.
|
|

|
## Usage
|
|
|
|
Run the binary. Use **Set save folder** from the main menu to enter your save
|
|
path manually (paste is supported). The menu is keyboard-driven:
|
|
|
|
| Key | Action |
|
|
|---|---|
|
|
| `↑` `↓` | Navigate |
|
|
| `Enter` | Select |
|
|
| `Esc` | Cancel / Back |
|
|
| `Y` / `N` | Accept / Decline in dialogs |
|
|
|
|
### Menu
|
|
|
|
1. **Set save folder** — enter your save folder path manually (paste supported)
|
|
2. **Recover save file** — pick a backup, preview metadata, overwrite the live save
|
|
3. **Create full backup** — copies all `savegame_*` files to `NotAlterra_Backups`
|
|
4. **Restore full backup** — overwrite the save folder from a previous backup
|
|
5. **Inspect save files** — view all GVAS properties of any `.sav` / `.bak`
|
|
6. **Manage UE5 Config (.ini) files** — backup, restore, or delete `.ini` files
|
|
7. **View disclaimer**
|
|
8. **Exit**
|
|
|
|
|
|
## Where Files Live
|
|
|
|
```
|
|
%LOCALAPPDATA%\Subnautica2\Saved\SaveGames\
|
|
savegame_0.sav
|
|
savegame_0.bak
|
|
savegame_0_1.bak
|
|
savegame_1.sav
|
|
...
|
|
```
|
|
|
|
### Linux (Proton / Steam Deck)
|
|
|
|
```
|
|
~/.steam/steam/steamapps/compatdata/1962700/pfx/drive_c/users/steamuser/AppData/Local/Subnautica2/Saved/SaveGames/
|
|
savegame_0.sav
|
|
savegame_0.bak
|
|
...
|
|
```
|
|
|
|
Use **Set save folder** from the menu to enter your save path (paste is
|
|
supported). The path exists only in memory for the current session —
|
|
re-enter it the next time you run the tool.
|
|
|
|
Backups are stored in `NotAlterra_Backups\` alongside the binary.
|
|
|
|
|
|
## Session Persistence
|
|
|
|
No configuration file is written to disk. The save folder path exists only
|
|
in memory for the current session — set it each time via **Set save folder**
|
|
from the main menu (paste is supported).
|
|
|
|
The disclaimer acceptance is tracked via a 0-byte sentinel file
|
|
(`NotAlterra_LICENSE_ACCEPTED`) alongside the binary. Delete this file to
|
|
re-prompt the disclaimer on next launch.
|
|
|
|
|
|
## Platform Support
|
|
|
|
- **Windows** — fully tested and supported.
|
|
- **Linux** — builds and runs. Use **Set save folder** to enter your save
|
|
path (typical Proton locations are shown under "Where Files Live" above).
|
|
|
|
|
|
## Safety
|
|
|
|
- Runs in your user context — no admin privileges required
|
|
- No network connections
|
|
- Read-only inspect mode won't touch files
|
|
- Pre-restore snapshots created automatically
|
|
- .ini delete requires a prior backup
