Mods: Where to find them and how to install them

What is a mod?

A mod is a small file with a .patch extension that when placed in a specific folder will modify your CitiesXXL game. Some common examples of what's available:
  • Highways
  • Maps
  • Special Buildings
  • Stadiums
  • Parks
Where do I find mods?

There are two main places to find mods for Cities XXL: The Steam Workshop (A) or (B)

A. Downloading Mods From the Steam Workshop

Open the Steam application. Click on the button for "Browse the Workshop"

Once inside the workshop you can browse through the entire list or choose one of the filters on the right to narrow down your search. To learn more about the mod, simply click on it.

To install the mod, click on the green "Subscribe" button.

That's it! The next time you run the game, the mod will be installed.

FYI: Mods from the Steam workshop automatically get installed in 
C:\Program Files (x86)\Steam\SteamApps\common\Cities XXL\Paks\mods

B. Downloading Mods from

Go to and become a member. You must be a member to download mods.

Browse the Cities XXL mods 
From the main page, click on the "Resources" tab.
From the "Resources" page, select "Cities XXL (2015)"

Click on whatever mod you'd like to learn more about. You can filter through the various mod types by selecting from the list of categories on the left side of the page.

Download the mod by selecting the black "Download Now" button

Place the downloaded .patch file in
C:\Program Files (x86)\Steam\SteamApps\common\Cities XXL\Paks

That's it! The next time you run the game, the mod will be installed.

Where do I find the mod in the game?

In order to see the mod, you may need to enable "Expert Mode" which is listed in the options.

The mod will be found in different locations based on what type of mod it is. In this case, it's a custom made office building so it's found by selecting "Custom Content" and then looking in the Star menu of the office buildings.

Where do I find the Real Highway Mod?

Again, make sure you've enabled expert mode, otherwise it won't work correctly.


  1. game crash when i copy patch files to the paks folder

  2. I maybe late to answer but for those still playing and will play xxl. Before downloading any mod. 1st download community pack mod and furniture pack mod so evertything you put will work. Place your mod inside Pak folder and create folder inside it. I hope it helps. Enjoy
