To install Project Zomboid server mods on FREAKHOSTING, open Game settings > Mods and map, paste each mod’s Steam Workshop link or id under Workshop items, add its mod id under Mod ids in load order, then review, save and restart. The server downloads the mods when it starts, and players download them when they join. Map mods also need their name in Map, before Muldraugh, KY.

​
Before you start

  • Check that each mod supports Build 42, the build your server runs. Build 41 mods often don’t work on Build 42.
  • Make a backup before adding several mods.

​
Workshop id or mod id?

Every mod needs two values. The mod’s Workshop page shows both. One Workshop item can contain several mod ids. Add only the ones you want, in the order the mod page asks for.

​
How to install mods on your Project Zomboid server

1

Open Mods and map

Open Game settings under GAME SETTINGS and open Mods and map (“Paste Steam Workshop links to add mods.”).
2

Add the Workshop items

Under Workshop items, paste the Workshop link or id and click Add. Repeat for each mod, including required mods.
3

Add the mod ids in load order

Under Mod ids, add each mod id. The list is in load order: required mods and frameworks go before the mods that need them.
4

Add map mods to Map (map mods only)

For a map mod, add its map name in Map before Muldraugh, KY. A wrong map name stops the server from starting.
5

Review, save and restart

Click Review and save, save and restart. The first start after adding mods takes longer while the server downloads them.
If the server doesn’t start after you change Map, set it back to Muldraugh, KY, save and start again.

​
How to remove a mod

Remove its mod id from Mod ids and its Workshop item from Workshop items, then save and restart. Removing a mod from a running world can delete its items and buildings from the map, so back up first.

​
Frequently asked questions

​
Why does the server say a Workshop item version is different?

A mod updated on Steam after the server last started. Restart the server so it downloads the new version. See Workshop mod errors.

​
Do players need to subscribe to the mods?

No. Players download the server’s mods when they join.

​
Can I add a Steam Workshop collection?

Add each mod of the collection one by one: its Workshop id under Workshop items and its mod ids under Mod ids.

​
Where are the mods saved in the config file?

In <Server Name>.ini in .cache/Server, on the WorkshopItems= and Mods= lines. Game settings edits them for you.
