The Voidtrain save game location on Windows is %LOCALAPPDATA%\VoidTrain\Saved\SaveGames\, while Microsoft Store installations store files inside %LOCALAPPDATA%\Packages\HypeTrainDigital.VoidTrain_7t701d8q7nf00\SystemAppData\wgs. Knowing where these files live allows you to create manual backups before modding or restore progress if an autosave slot is overwritten.

Save File Paths by Platform

Depending on your platform and distribution store, Voidtrain places your save game and configuration files in different directories on your system.

Platform / StoreSave Game LocationConfiguration File Location
Windows (Steam / Epic Games Store)%LOCALAPPDATA%\VoidTrain\Saved\SaveGames\%LOCALAPPDATA%\VoidTrain\Saved\Config\WindowsNoEditor\
Windows (Microsoft Store)%LOCALAPPDATA%\Packages\HypeTrainDigital.VoidTrain_7t701d8q7nf00\SystemAppData\wgs%LOCALAPPDATA%\VoidTrain\Saved\Config\WinGDK\

For Steam users, the local save directory maps deeper under a Steam Cloud folder organized by your unique Steam account ID:

%LOCALAPPDATA%\VoidTrain\Saved\SaveGames\SteamCloud\<Steam ID>\Game\

Inside this directory, individual world saves are categorized under SaveSlot subfolders containing the primary world.sav file.

How to Access the Voidtrain Save Folder on Windows

You can navigate directly to your local save files using the Windows Run dialog without having to manually unhide system folders.

  1. Press Windows Key + R on your keyboard to open the Run prompt.
  2. In the text field, paste %appdata%/../Local/VoidTrain/ and click OK.
  3. Open the Saved folder, followed by SaveGames.
  4. Open SteamCloud, then the folder named after your numerical Steam ID.
  5. Enter the Game folder to find your active save slot directories.

To back up your campaign, copy the entire save slot directory or the relevant world.sav file to a secure backup location on your drive before editing game data or installing mods.

Save Slot Structure and Autosave Overwrites

Voidtrain provides a specific allocation of slots across its save system:

  • 3 slots dedicated to autosaves (the first three slots in the menu).
  • 5 slots dedicated to manual saves.

Because the first three slots are reserved for autosaves, starting a separate solo playthrough can automatically overwrite existing autosave progress from a co-op run if manual saves were not created.

According to official developer guidance from HypeTrain Digital, client players connecting to a co-op host rely on the inventory data stored in their own latest save. If a client player starts a new solo file and utilizes those same autosave slots, their active co-op character equipment can be overwritten. To avoid losing guns or gear, make an explicit manual save in one of the five manual slots before switching between multiplayer and solo sessions.

Restoring Save Files from Steam Cloud

If an autosave slot is accidentally overwritten or you need to recover an earlier world state, the game host can retrieve older save states through the Steam Cloud web portal.

  1. Close Voidtrain completely on your PC.
  2. Open your web browser, log in to Steam, and navigate to your account's Steam Cloud page.
  3. Locate Voidtrain in your games list and find the save file that matches the date and time of the session you want to restore.
  4. Download the target save file to your computer.
  5. Rename the downloaded file to world.sav.
  6. Open your Run window (Windows + R) and navigate to %appdata%/../Local/VoidTrain/.
  7. Browse to Saved > SaveGames > SteamCloud > [Your Steam ID] > Game.
  8. Place your renamed world.sav file into the target folder under SaveSlot.
  9. Launch Voidtrain and choose the corresponding slot from the load menu. If a Steam Cloud conflict prompt appears on launch, choose to use your local files.

Managing Steam Cloud Sync

When troubleshooting save conflicts or installing community mods into the VoidTrain\Content\Paks directory, you may want to prevent Steam from immediately overwriting local save edits with cloud data.

  1. Open your Steam Library.
  2. Right-click Voidtrain and select Properties.
  3. Under the General/Updates settings, find Enable Steam Cloud synchronization for Voidtrain.
  4. Uncheck the option to disable cloud saves for the game.
