This page is for installing mods manually from individual zip files. See the Download Mods page for download links.

NOTE: Not all mods are zipped up the same. Some contain the mods folder in them, some do not. The ones that contain the mods folder go in the WurmLauncher folder. The ones that do not contain the mods folder go in the WurmLauncher\mods folder.

1. Close any running copies of Wurm Unlimited.
2. Find your WU folder: <steam folder>\steamapps\common\Wurm Unlimited\WurmLauncher)
3. Unzip the contents client_modlauncher-0.15.zip (or current version) into the WurmLauncher folder, overwrite any files there.
4. Unzip the contents of any individual mod zip files into the WurmLauncher folder.
5. Run patcher.bat in the WurmLauncher folder to patch the game.
6. Start Wurm from Steam.

Important Note: Pay attention to any error messages the patcher.bat gives you. Windows 11 seems to default to a Windows path instead of the WurmLauncher folder thereby breaking the relative pathing of in the patcher.bat file. The fix is to open a powershell from the WurmLauncher folder in File Explorer so that you're in the correct folder when you run the patcher batch file.

The process is the same for copying files. You'll have to go into Steam, your Library, right click on the Wurm Unlimited listing, Manage, Browse Local Files. From there you can extract (or copy) your mods into the WurmLauncher folder.

You will need to set your patcher.sh file as executable from a terminal. Browse to the WurmLauncher folder with your file manager, then open a terminal there.

sudo chmod -x patcher.sh

sh ./patcher.sh

You should see the message that the game has been patched.

Linux can be set up to run more than one instance so you can play more than one character at a time (alts). See the How to Use Alts page.
