From JC2-MP Documentation
Welcome to the JC2-MP Windows server tutorial. This page will explain the very basics of setting up a Windows server. This tutorial assumes you already have some basic Windows knowledge.
Downloading the Just Cause 2 Multiplayer mod
In your steam client head over to the Store page, then type "Just Cause 2 Multiplayer" in the search bar and click on it.
Now you should arrive and the Just Cause 2 Multiplayer page, proceed to download the mod by clicking on the PLAY button.
Downloading the server
Once you have the Just Cause 2 Multiplayer mod on your computer, we will also automatically have access to the JC2-MP dedicated windows server. Head over to your library and drop down to tools.
Once you arrived at the tools page type "Just Cause 2" in the search bar.
Editing the server options and starting the server
You can now start the server by simply double clicking on "Just Cause 2: Multiplayer - Dedicated Server".
But before we do that let's configure our server.
Head over to where you have installed Steam, by default this is
C:\Program Files (x86)\Steam\...
Now navigate to where the dedicated server is located.
C:\Program Files(x86)\Steam\steamapps\common\Just Cause 2 - Multiplayer Dedicated Server\...
Rename this to config.lua, and then open it by right clicking and selecting "open with" then choosing Notepad or any other text editor.
Once you have opened it, you can edit your server slots and many other options there. For additional information, read the readme that is in the same folder. Simply follow the instructions in the config and readme, and have fun with your server.
