How to install mods on a American Truck Simulator server

Installing mods on an American Truck Simulator (ATS) server allows you to expand the game's capabilities — add new trucks, maps, and improvements. Proper server mod configuration ensures identical content for all players, eliminating synchronization errors and making co-op sessions stable and engaging.

Prepare mods in your local game

Before uploading files to the server, you need to properly prepare them on your computer. Launch American Truck Simulator, go to "Mod Manager" and activate all modifications you want to see on the server.

After activation, load into the game world, enter your profile and click "Drive".

Generate server files

For the server to "understand" which mods to use, you need to create special configuration files. To do this, open the developer console (usually the ~ or ё key). If you don't have the developer console enabled, you can enable it by following these instructions.

In the console line, enter the following command:

export\_server\_packages

Press Enter. The game will automatically create two required files: server_packages.sii and server_packages.dat. After successfully executing the command, you can close the game.

Locate the created files

Now you need to find the generated files and the mods themselves on your computer. Navigate to the game documents folder, the path usually looks like this: C:\Users<Username>\Documents\American Truck Simulator.

You will need:

1. Files server_packages.sii and server_packages.dat (located in the root folder).

2. Mod files with .scs extension (located in the mod folder).

Upload files to the server

Log into your hosting game panel and open "File Manager" or connect via FTP.

Navigate to the server directory at the following path: .local/share/American Truck Simulator

Upload here (to the root of this folder) the files server_packages.sii and server_packages.dat. Then upload the mod files (.scs) to the mod folder at this path .local/share/American Truck Simulator/mod on the server.

Restart the server

After completing the upload of all files, restart your server. During loading, the server will read the new configuration files and load the installed mods. Your server is now ready to work with new content!
