Add Workshop Mods to a Killing Floor 2 Server

This article explains how to add Steam Workshop mods to your Killing Floor 2 server.

1. Find the mods you'd like to use in the Killing Floor 2 Workshop.
2. Start your server at least once to generate the config files.
3. Stop your server.
4. Click on the Files tab in Command Center.
5. Click on KFGame > Config > LinuxServer-KFEngine.ini
6. Scroll to the bottom and find this heading: [IniVersion]
7. Right above that added the following, where the numbers are the IDs for the workshop items:

[OnlineSubsystemSteamworks.KFWorkshopSteamworks]
ServerSubscribedWorkshopItems=12345678
ServerSubscribedWorkshopItems=23456789

📘

Workshop IDs

The workshop ID you need for the above can be found at or near the end of the web address for the mod on Steam's Workshop page for the mod. Example:
https://steamcommunity.com/sharedfiles/filedetails/?id=12345678

In this case, 12345678 is the workshop ID.

8. Find the following header in the same file: [IpDrv.TcpNetDriver]
9. Add this line to that section right below the header (This DownloadManagers line should be above any others in that section):

[IpDrv.TcpNetDriver]
DownloadManagers=OnlineSubsystemSteamworks.SteamWorkshopDownload

10. Click on Save
11. Start your server and it should download the mods.

Enjoy!
