This is a tiny local patcher. It does not include or redistribute original game assets.

Installation

1. Extract the ZIP.

2. Close Subnautica 2.

3. Run Install-SpeedPatch.bat.

4. Start the game.

If the game is installed outside the default Steam location, run PowerShell in the extracted folder:

powershell -ExecutionPolicy Bypass -File . Apply-Subnautica2SpeedPatch.ps1 -GameRoot "D: SteamLibrary steamapps common Subnautica2"

Run PowerShell as Administrator if Windows blocks writing to Program Files.

Multiplayer

All players should install the patch locally. If only one player has it, movement may not match between clients.

Uninstall

Close the game and run Restore-SpeedPatch.bat, or verify game files in Steam.

Compatibility

The patch is version-sensitive because it edits Subnautica2-Windows.ucas at known offsets. The script verifies the bytes before writing. If it reports unexpected bytes, stop and wait for an updated version.

Notes

Steam game verification or a Subnautica 2 update can remove the patch. Run the installer again after verification/update if the script still confirms compatible bytes.
