Resetting Atlas Reactor Settings outside of the game

To reset the settings outside of the game, you'll need to remove one of the registry files for the game. Before doing this, please make sure you backup your registry first.


  1. Open the Run box with the keyboard combination Windows key + r.
  2. In the Run line, enter “regedit” (without quotes)
  3. Click 'OK'
  4. Say 'Yes' to User Account Control (Windows Vista/7/8.x/10)
  5. Select File, then 'Export'
  6. Save this file somewhere you can find it and name it. This is your registry backup if you need to revert back to it.
  7. Once you've saved your registry, navigate to HKEY_CURRENT_USER\Software\Trion Worlds\ and find the folder named 'Atlas Reactor'.
  8. Right click the 'Atlas Reactor' folder and select 'Delete'.
  9. Once this is done, close the Registry Editor and launch the game again. The game will now be using default settings.
