Map mods are one of the easiest ways to make your Project Zomboid server feel unique. Whether you want new towns to explore, extra loot routes, or custom roleplay hubs, the right map mods can completely change how your players experience the apocalypse.

In this guide, we’ll explain what map mods are, how to install them on your Project Zomboid server, and some best practices to keep your saves stable and your players happy.

What Are Map Mods In Project Zomboid?

Map mods are custom additions or changes to the in-game world. Instead of just tweaking items or gameplay balance, they alter the physical layout of the map.

Map mods can:

  • Add new towns or regions with custom buildings and streets
  • Expand existing vanilla areas with more locations to loot or claim as bases
  • Overhaul specific zones (e.g. a reworked Riverside, Muldraugh, or challenge area)
  • Create event or scenario maps for roleplay, PvP, or special server seasons

Most map mods are installed via the Steam Workshop, and each one usually provides:

  • A Workshop ID – used by the server to download the mod
  • A Mod ID – used by the game to load the mod’s content
  • A Map name / folder name – used in the server’s Map= setting to actually place it in the world

Because map mods change the world geometry, they’re more sensitive than regular mods:

  • Removing or changing maps mid-wipe can result in missing bases, broken chunks, or void areas.
  • Overlapping maps on the same coordinates can cause floating buildings, invisible walls, or messed up streets.

That’s why installing and managing them carefully is important.

How To Install Map Mods On Your Server

Below is the step-by-step process for adding map mods to your server using a modded Project Zomboid host.

1. Get The Workshop & Mod IDs

First, gather the information from Steam:

  • Open Steam and go to Project Zomboid → Workshop
  • Find the map you want and subscribe to it
  • On the Workshop page, note:Workshop ID
    Mod ID
    Map name (often shown in examples like Map=MapName;)

It’s a good idea to keep these in a small text file so you don’t lose track when you add more maps.

2. Log In To The Game Panel

Now head to your server:

  • Log in to the game panel
  • Select your Project Zomboid server
  • Stop the server before making any changes

Stopping the server first helps prevent issues with config files or downloads.

3. Install The Workshop Item

Next, install the map’s Workshop item on the server:

  • Go to the Workshop tab in the panel
  • Enter the Workshop ID for the map
  • Click Install

This tells the server which Workshop item it should download.

4. Enable The Mod ID

Once the Workshop item is installed, you need to enable the map mod itself:

  • Go to the Mods tab
  • Enter the Mod ID of the map mod
  • Save your changes

This ensures the game actually loads the mod when the server starts.

5. Add The Map To The Config

Now you’ll link the map into the world:

  • Go to the Files tab in the panel
  • Use the search to find the configuration file that contains the Map= line (commonly Zomboid.ini or similar server config)
  • Open the file and locate the line that starts with:Map=
  • Add the map name exactly as shown on the Workshop page

Example with one custom map and the default map:

Map=MapName1;Muldraugh, KY

A few important points:

  • The map name must match exactly (spelling and capitalization)
  • Multiple maps are separated by semicolons
  • Order matters for some maps, especially add-ons

Save the file when you’re done.

6. Restart The Server And Test

Once everything is configured:

  • Go back to your server page in the panel
  • Start or restart the server

After it starts:

  • Join the server with a client that also has the same Workshop map subscribed
  • Travel or teleport to the new map area
  • Confirm the map loads properly and works as expected

If something is wrong (map not loading, errors on startup), double-check:

  • Workshop ID
  • Mod ID
  • Map name in the Map= line

Best Practices For Using Map Mods

Map mods are powerful, but they can cause problems if they’re managed recklessly. These best practices will help keep your server stable and your players happy.

1. Use A Clean Load Order

A good general order for mods is:

  • Maps
  • Tile packs
  • Framework or character adjustment mods
  • Vehicle mods
  • All other mods

This helps ensure the world and tiles are loaded first, before other systems try to use them.

2. Avoid Changing Maps Mid-Wipe

Whenever possible, avoid:

  • Removing map mods mid-wipe
  • Replacing major maps while players have established bases

Doing so can:

  • Break player bases
  • Leave chunks missing or bugged
  • Trap characters in invalid areas

If you want to change your map setup, plan it for the next wipe and announce it in advance.

3. Double-Check IDs And Names

Many map issues come from simple typos. Always verify:

  • Workshop IDs are correct
  • Mod IDs are spelled exactly as on the Workshop page
  • Map names match exactly in the Map= line

If a map isn’t loading, this should be the first thing you review.

4. Test New Maps Before Going Live

For big changes or multiple new maps, it’s smart to:

  • Use a test server or a temporary instance
  • Invite a few staff or friends to join
  • Explore the map and look for:Performance problems
    Missing tiles or buildings
    Obvious conflicts with existing maps

Once you’re satisfied, add the map to your main server for the next wipe.

5. Backup Before Major Changes

Before adding a lot of new map mods, removing old ones, or doing a major cleanup:

  • Make a backup of your world and configuration files

If something goes wrong, you can roll back instead of starting over.
