How To Install Mods on Your Arma 3 Server
Learn how to install Steam Workshop mods on your Arma 3 dedicated server.
Arma 3 has one of the largest modding communities in gaming. Mods can add new maps, weapons, vehicles, missions, and total conversion experiences. Here is how to install them on your server.
Installing Mods via Startup
Find the Mod IDs
Browse the Steam Workshop for Arma 3 and find the mods you want to install. Copy the Workshop ID from each mod's URL. The ID is the number at the end of the URL (e.g., https://steamcommunity.com/sharedfiles/filedetails/?id=123456789).
Open the Startup Page
Log in to the XGamingServer Panel and select your Arma 3 server. In the sidebar, click Startup.
Enter the Workshop Mod IDs
Find the Workshop Mod IDs or Mods field in Startup. Enter the mod IDs separated by semicolons (e.g., 123456789;987654321;111222333).
Restart Your Server
Go to Console and restart your server. The mods will be downloaded automatically during startup.
📝 Note: Mod downloads may take some time depending on size. Watch the console for download progress and any errors.
Installing Mods Manually
If you need to upload mods manually (for example, custom or private mods):
Stop Your Server
Log in to the XGamingServer Panel and Stop your Arma 3 server.
Upload the Mod Files
In the sidebar, click Files. Upload your mod folder (usually named with an @ prefix, like @CBA_A3) to the root server directory.
Add the Mod to Startup
Go to Startup and add the mod folder name to the mods list (e.g., @CBA_A3).
Start Your Server
Start the server and verify the mod loads correctly in the console output.
⚠️ Warning: Players connecting to your server must have the same mods installed on their client. Make sure to communicate which mods are required. The Arma 3 Launcher will typically auto-detect and prompt players to subscribe to the required mods.
💡 Tip: CBA_A3 (Community Base Addons) is a dependency for many Arma 3 mods. Install it first if your mods require it.
