How to Install Workshop Mods on Your Arma 3 Server

Install and configure Steam Workshop mods on your Arma 3 server.

Steam Workshop mods enhance Arma 3 with new content, weapons, vehicles, maps, and gameplay features. This guide covers how to add mods to your server that players will need to download to connect.

Players must have the same mods installed locally to join your server. They can subscribe to mods through the Steam Workshop and manage them via the Arma 3 Launcher.

Adding Mods via Control Panel

  1. Navigate to the Wabbanode Control Panel and Stop your server. Wabbanode control panel with stop button
  2. Click the Settings tab and select Arma 3 Server Settings. Wabbanode Settings tab with Arma 3 Server Settings selected
  3. Locate the Mods field and enter your mods in the format @mod1;@mod2;@mod3.. Mods field in Arma 3 Server Settings
  4. Click Save and Start your server.

Mod Format

Mods are specified using the @ prefix and separated by semicolons:

@CBA_A3;@ace;@RHSUSAF;@RHSAFRF

Finding Mod Names

  1. Go to the Arma 3 Steam Workshop.
  2. Find the mod you want to install.
  3. The mod folder name is typically shown in the mod's description or can be found after subscribing.
  4. Common format: @ModName or @WorkshopID

Tips

  • Load order matters - put dependencies like CBA_A3 first
  • Test mods one at a time to identify conflicts
  • Provide your players with a mod list or collection link
  • Keep mods updated to match the Steam Workshop versions

Mod mismatches will prevent players from joining. Ensure all players have the exact same mods and versions installed.

Your server mods are now configured. Share the mod list with your players so they can subscribe and join your operations.
