A patch is a game programming improvement, made by the game developers (Avalanche Studios) to improve game performance and fix Just Cause 3 Bugs and glitches.

These are not to be confused with Modifying, which is when the player community alters game code for fun.

While we’re glad you’re getting familiar with Medici before Tuesday, this does mean that you’re playing the unpatched version of the game, and a host of fixes and improvements will be available within the next 24 hours.

Fourth patch and Sky Fortress compatibility content

Sources: Here and here.

A 1.1 GB patch has been released for PC, with console patches to follow soon. The patch is reported to mostly improve performance, but also add compatibility to the first expansion pack, the Sky Fortress.

Quote from the second source:

So before we get into the nitty-gritty, we'd like to apologise for the belated release of our latest patch notes - the game launch in Japan yesterday and had the team rushed off their feet and we needed solid confirmation on what actually went into the update - as you can see it wasn't a small download. We know how important these updates are to you and in future we'll make sure our patches and notes are released correspondingly.

So our latest Patch (1.1GB) includes a few alterations to JC3 for the Japanese release of the game. It also contains some improvements to online functionalities, and stability. Here’s a more technical breakdown of what the patch includes:

  • Japanese Audio added
  • Online

-- Protocol change for GetStats to reduce server bandwidth -- Further improvements to GetStats, adding zlib compression to the response

  • Stability

-- Fixed raycast scheduler threading issues The Just Cause 3 team continues to work on optimisations and fixes. Thank you for your feedback so far, we want to let you know that your comments aren’t falling on deaf ears. If you have any questions for us, please fire away below!

Sixth patch and Mech Land Assault compatibility content (v1.04)

Quote from this page:

Just Cause 3 Update 1.04 Today Preps for Mech Land Assault DLC, Which Is Out on June 3

May 31, 2016

A 1.50GB download on PlayStation 4, developer Avalanche Studios has released Just Cause 3 update 1.04 on PS4, Xbox One, and PC to help fix some issues and prep for the new Mech Land Assault DLC. Here’s the full list of patch notes for today’s update:

Preparation for new content
This includes preparation to make sure your new mech can get around (and tear up) Medici comfortably. The Kousava Rifle was designed by a competition winner as part of a promotion with a major retailer and can now be redeemed in game or bought separately.
  • Adjusted region boarders
  • Bug fixes
  • A new island for the Mech Land Assault (nearly 20km squared in game) means we have had to shift a few of the boarders of Medici around.

Priced at $11.99/€11.99/£9.49, or free as part of the $24.99/€24.99/£19.99 Expansion Pass, Mech Land Assault releases on June 3 for Expansion Pass owners and June 10 for everyone else.

Here’s what to expect from Mech Land Assault, which takes Rico to the new island of Lacrima, where the Black Hand runs a prison camp: Defended by huge powerful Mechs, Rico will need the new Bavarium Power Core rifle to disable their shields and hijack them. Once inside, Rico can use their powerful cannons and the GRIP Gravity Guns to hurl and smash the enemy into pieces.

  • Pilot two types of powerful Mech and drive them anywhere in Medici.
  • Unleash the Mech’s Gravitational Remote Influence Projector or “GRIP” to attract and hurl objects at your enemies.
  • Jump and smash helicopters from the sky or ground pound tanks with the GRIPS’s “Force Pulse” attack.
  • Prove your skills and earn upgrades in Mech arena challenges.
  • Call in a Rebel Mech buddy for extra firepower when the going gets tough.
  • Includes a powerful new energy weapon, the Bavarium Power Core rifle.

The final DLC pack for Just Cause 3, Bavarium Sea Heist, will be out by the end of summer 2016.

Seventh patch and Bavarium Sea Heist compatibility content (v1.05)

Quote from a Steam page:

Patch 1.05 incoming

Some small unannounced updates (2019.03)

It has been reported by more observant players that some weapons that used to be rare are now carried by members of The Rebellion.

Some other update sometime between v1.01 and now

Medici Military and/or Black Hand Custode 29s and CS Powerrun 77s seem to have severely increased damage on their MGs.

It's not known if this was an intentional part of any patch.
