How To Connect To Your Just Cause 3 Multiplayer Server

Here is how you and your friends can join your Just Cause 3 Multiplayer server. Your server always runs the newest JC3MP version, so keep the mod up to date in Steam.

What you needNotes
Just Cause 3 on SteamRequired. JC3MP runs on top of the Steam version of the game.
Just Cause 3: Multiplayer ModRequired. Free on Steam.
Just Cause 3 DLCOnly if the server owner has set required DLC.

Tip

Steam updates the Multiplayer Mod automatically. If you can't join, make sure Steam has finished updating it.

Connecting From the Server Browser

  1. 1
    In Steam, launch Just Cause 3: Multiplayer Mod.
  2. 2
    Open the server browser and type your server name in the search box.
  3. 3
    Select your server and click to join. If you set a server password, enter it when asked.

The first time you join, the game downloads the server's packages, such as freeroam, chat and the spawn menu. This only takes a moment.

Note

It can take a few minutes for a new server to appear in the server browser after it starts. If your server doesn't show up at all, check that Server Browser Listing is turned on.
