Modding is the action of modifying game files and 3D models in order to add or change gameplay mechanics. Modding is something that is done by the community rather than by the developer, even though most of the Modding projects are tolerated and even supported by the current Publisher Focus Home Interactive.

The official Cities XL modding site gives access to a plugin for 3DSmax, a 3D modelling tool, which allows 3D models to be converted to the Cities XL in game format.

How To Install Mods[]

Either use the mod manager listed above (recommended) or if you're keen to do it yourself (there's nothing difficult as long as you understand how file systems work) then follow these instructions:

  1. Make sure the game is not running.
  2. Download the Mod you want.
  3. If it is a zip/rar file then extract the ____.patch file(s) inside.
  4. Move the _____.patch file(s) to:
64 bit Operating System
C:\Program Files (x86)\Focus Home Interactive\Cities XL 2011\Paks
32 bit Operating System
C:\Program Files\Focus Home Interactive\Cities XL 2011\Paks

If the mod file is a ____.exe file (E.g. The Unlocker Mod 5) then you need to just run it as you would any program and follow the installation instructions...


Modding in Cities XL began in its infancy, starting with the Beta version of Cities XL 2009. A German user called Okeanos took some deeper looks into the game's files and began to program the first tools for unpacking game files shortly after that. As Cities XL was an MMO in those times, the release of the tools lead to a very controversial discussion on the German community site Cities XS . As most of the users there didn't want to see the Unpacker and Packager tools released, the Cities XS administrators Mudder and André090904 decided that the tools won't be released while Planet Offer (PO) lasts. This was considered a step in the wrong direction for Cities XL Modding.

However, a small group of people which were picked up randomly by Cities XS administrators began to experiment and a secret Modding team began to develop some mods, which would never be released as it was considered dangerous for the PO.

Even when PO ended in March 2010, Cities XS still refused to release Okeanos' Packager and Unpacker even though Okeanos wasn't active in the Cities XL community anymore. So a Cities XS user called haltendehand leaked both tools shortly afterwards, and was nearly banned from the site. All in all, the community finally had the tools needed to mod anything not related to building models.

Over the next months, knowledge of how to open and edit both texture files and bumpmaps of buildings was revealed, but the community still wasn't able to edit the 3D model itself. Meanwhile the French website, Generation City, released their own version of a Cities XL Packager tool, called PakUnpak.

When Focus Home Interactive announced Cities XL 2012 in early 2011, they also announced that modding tools will be included. Soon all players will have the capability to modify and create new 3D buildings in Cities XL.
