Adding custom maps to your Project Zomboid server enhances gameplay by introducing new locations, challenges, and environments. Whether you want to add a single custom map or a full map pack, follow this step-by-step guide to install and configure new maps properly.

Step 1: Download the Custom Map

Before adding a new map, find a compatible one from:

• Steam Workshop – The most reliable source for modded maps.
• Third-party websites – Ensure compatibility with your game version.

Step 2: Subscribe to the Map Mod in Steam Workshop

If you’re using a Steam Workshop map:

1. Go to the Steam Workshop and find your desired map mod.
2. Click Subscribe to add it to your game.
3. Start Project Zomboid once to allow it to download.

For third-party maps, download the ZIP file and extract it to:
C:\Users\YourUsername\Zomboid\mods

Step 3: Locate the Map Mod ID and Workshop ID

To activate the map, you need two key pieces of information:

• Mod ID – Found in the mod’s description or mod.info file.
• Workshop ID – Found in the Steam Workshop URL (the numbers at the end).

Step 4: Add the Map to Your Server Files

1. Access your server folder (via FTP or local hosting).
2. Navigate to:
   • Zomboid\Server\servertest.ini (for settings).
   • Zomboid\Server\servertest_SandboxVars.lua (for custom settings).
3. Open servertest.ini and locate these lines: Mods= WorkshopItems= Map=
4. Add the required IDs:
   • For Mods: Add the Mod ID after Mods=
   • For Workshop Maps: Add the Workshop ID after WorkshopItems=
   • For the Map: Add the exact map name after Map=
   Example Configuration: Mods=Over the River;Bedford Falls WorkshopItems=123456789;987654321 Map=Over the River;BedfordFalls;Muldraugh, KY (Separate multiple entries with semicolons ;.)

Step 5: Restart the Server

1. Save your changes in servertest.ini.
2. Restart your Project Zomboid server.
3. Check the logs for errors to ensure the map loads correctly.
