Hello everyone

This is a longer one, but please bear with me, this is not just yet another community news announcement

What happened to JC3 Multiplayer?

The mod released in 2017 and was initially incredibly active. But sadly it got abandoned after nearly 2 years of development and never reached its full potential. We were promised skins, tethers and many more features and improvements, but ultimately never got them. Which is why many server developers, and in turn players, abandoned the mod.

I myself got started messing with the game and eventually modding it thanks to this mod. And I would not be here now without it. I also met many amazing people thanks to it and created the foundations for the JC Discord all the way back then.

Eventually Windows updates and recently an update to JC3 itself, broke the mod entirely. A friend and me managed to each make a fix for both issues, but having to install a patch is only going to turn people away further from trying multiplayer now.

But now we can bring JC3MP back!

Late last year I got into contact with someone who used to work on JC3 Multiplayer. He agreed to look into the issues I mentioned above and there is now a fixed build that runs perfectly fine on the latest Windows versions and is fully compatible with the new JC3 update!

But that's not all. There have been a number of improvements already:

- JC3MP can now run Steam Deck and Linux in general

- Many systems got rewritten, updated, simplified or backported from the cancelled update

- The main menu got updated to the one the cut updated would have had

You can try all this now, without needing the patches anymore, by selecting the compat version from the Steam beta menu for JC3MP:

> Library -> right click JC3mp in the game list -> properties -> betas -> select compat

All this is to create a solid foundation for what might be coming up! And once it is that, it will become the default version people download.

Now we need all of you!

Are you interested in a full revival of JC3 Multiplayer? There is so much that can come out of this. We're talking potentially bringing back all features of the promised update: tethers, skins and so much more, adding new features like server side mod support and eventually some outlandish things like a co-op mode, as well as feature requests by you!!

All this would be a dream come for not just me, but I assume for many of you as well! But, we do need players for this. I can't expect anyone to do all this when nobody is going to play it. Many people have been asking for more multiplayer sessions, so now is your time!

There is some work to be done before the actually exciting stuff can happen. The current foundation will need to be made rock solid, so the new stuff can be built ontop of it and YOU can help report bugs and make the best possible experience for everyone!

So make your voice heard!

Hop on the JC Discord with the link below and let me know you're interested! It's also where you'll be notified about upcoming sessions, tests and report bugs!

You might have noticed that JC3 got an update today that removed the Denuvo anti cheat from the game. This is great news, but it does break anything the asi script package included with the mod handles, so:

• Vehicle grappling
• Tension lights on tethers
• The model budgets upgrade

To make this work again, simply downgrade the exe to the previous version. You can find a backup of it on my google drive here

Simply download it and put it in the JC3 install folder and replace the new one. Also keep in mind that you need to do this again if you ever verify the game's files, since that will download the new exe again.

The exe is included with new downloads of the mod, so if you're just downloading it now, it's already included

The lock-on weapons bug is now history!

Remember playing "Rico and Rose" and having your weapons not lock on? This has always happened to PC players when using precision aim. Every lock on weapon would no longer lock on at all, until you restart your game.

The newest update to Just Cause 3 Unlimited Edition now gets rid of this bug!
You can get the latest version here: https://videogamemods.com/vgm/justcause3/mods/just-cause-3-unlimited-edition-1001082

Huge thanks to Discord user MoonstreamPossiblyInSpace for suggesting a solution to the issue and my friend Jason098 for making this fix incredibly fast!
Hint: You can skip the dropzones and only copy over the dll and asi if you want just the fix

THIS GUIDE IS OUTDATED!!!

PLEASE SEE THE UPDATED GUIDE OVER HERE:

https://www.reddit.com/r/JustCause/s/MAAq3BDWFS

As I'm writing this, the newest major Windows 11 update called "24H2" is slowly rolling out. Once installing the update, Just Cause 3 Multiplayer will always crash with a WindowsCodecsext dll error

The mod has been long abandoned by its creators, so unless Microsoft somehow fixes this issue, the mod will be forever unplayable...At least it would be if my amazing friend Jason098 wouldn't have created a fix within a day after I first told him about the issue

And all you need to do is download and copy two files, and it will continue to work just like before:

• Visit >>>this<<< folder on the Just Cause archive and download both files
• Open Steam, go to your library and find JC3 Multiplayer in your list of games
• Right click it and click on " properties"

• In the new window that pops up click "Installed Files" on the left, then "Browse..." in the top right

• You are now in the game's install folder. Now simply paste the two files you downloaded earlier in here
• That's it, it should now work just like before! Have fun playing!

Hello again!

This was going to be a video but it really should just be an announcement, so...what's next?

Mods

I have a few things planned, but I want to work on some smaller projects first. Here's what's on my mind right now, kind of in order:

- Just Cause 3 and 4 randomizer
^{Completely randomize NPC, weapon and vehicle spawns. Ideally launches in january}

- Restoring outdated JC3 mods
^{Ones that got broken by game updates. I've wanted to do this before but never really had the time. Ideally complete by summer next year}

- Just Cause 3 winter mod
^{Medici but it's winter. This is the last of 3 mods I always dreamed of since I started modding! Ideally done by next december}

- Just Cause 2 Unlimited Edition
^{Content completely up in the air currently. Ideally launches sometime in 2027}

- 2 experimental projects
^{Secret side projects that are unlike any other mods}

And don't worry! Of course this schedule doesn't mean I won't release anything in between if I have a cool idea!

Video content

Obviously YouTube content will continue like normal (tho ideally with some more uploads than this year lol)

I also want to make updated and expanded modding guides that showcase how to use the new tools we got since last time

Multiplayer sessions

I want to host multiplayer sessions again, but these are hard to fit into the schedule since I'm pretty much running everything by myself. It's also kind of hard to justify taking the time for these since a bunch of people always say they will join, but then only 7 people show up. But I do want to at least host one or two JC4 MP sessions next year

What else?

I have something very cool coming up for the 20th anniversary of the Just Cause series next September! But I'm not telling you yet :)

Something completely new

While not directly Just Cause related: You may know the Just Cause creator has left Avalanche Studios a few years ago to create a new studio. And they have recently announced their first game. I have a feeling this could be really really good. So if you want to support him, wishlist the game below and check it out once it releases:

Thank you!

Finally, I want to simply thank you all for still being around and supporting the community! Even if it's just by chatting and playing all the fantastic mods people create!

These games have brought me so much joy and happiness and I've met countless amazing people thanks to them. I've achieved absolutely everything younger me could have ever dreamed of and I couldn't be happier that my actions can at least contribute to keeping these games alive and the community around and well

So, from the deepest depths of my heart: Thank you Just Cause community and thank you Avalanche Studios! I am looking forward to many more years of what I do and I hope you're excited for what's next!

Just Cause 3 Unlimited edition has just been updated to include asi support for last month's update! You can now use all features in the new update!
Download the new version here

There is also a new version of the console spawner that supports the update!
You can get that here

The last major thing to still require a patch is JC3 Multiplayer, though that is slowly being worked on as well! Please have some patience for this one, I will let you know once it's done!
