Notes and stuff
Edit: The long-anticipated Just Cause 3 Multiplayer Mod is finally getting a proper launch on 20th July. It will be on Steam and everything.

The mod by fan group Nanos GbR has been in beta since January, but it's worked out most of the kinks in the half-year it's been publicly available.

This multiplayer mod will allow players to create their own game modes, but it's mostly meant for futzing around as it supports hundreds of players per server - even if they all look like the exact same man. Now you can have aerial battles, vehicular races, or emulate the group skydiving scene in Point Break.

FAQ

HOW TO INSTALL THE MODIFICATION?

Simply download the installer from our website and install it in any directory. Then simply launch the newly created launcher.

WHAT ARE THE SYSTEM REQUIREMENTS?

The system requirements are the same as those of Just Cause 3. If you can run the singleplayer, you will be able to play the game. The modification requires you to have Steam running and to be logged into an account owning Just Cause 3.

CAN I DOWNLOAD THIS MOD DIRECTLY FROM STEAM?

This Beta release is only available on our website. Future versions may be available on Steam.

HOW CAN I APPLY FOR BECOMING A TESTER?

You should not apply as a tester. We are inviting people from the community ourselves to join our team.

THE GAME DOES NOT LAUNCH. WHAT CAN I DO?

You can try running the modification as an admin and try to delete the "cache" folder in your JC3:MP installation directory. If that does not help be sure to check out our support forums.

MY SERVER IS NOT ANNOUNCED ON THE MASTERLIST.

You need to generate an auth-key and then add it to your masterlist package. Your server won't be listed otherwise.

2017, everybody that played this before has likely forgotten it, so this is sadly a dead post (f=rip)
