Expanding the Rotation

Killing Floor 2 has an integrated Workshop system that allows the server to automatically download and sync map files with connecting clients. This ensures that players always have the correct version of a map without needing to manually browse the Workshop themselves.

​
1. Subscribing the Server

  1. Find the Workshop ID of the map you want (the number in the URL).
  2. Open PCServer-KFEngine.ini via the File Manager.
  3. Locate the [OnlineSubsystemSteamworks.KFWorkshopSteamworks] section.
  4. Add a new line for each map: ServerSubscribedWorkshopItems=123456789

​
2. Defining the Map Summary

The server needs to know how to display the map in the menu.
  1. Open PCServer-KFGame.ini.
  2. Add a new map entry at the bottom of the file following this format: 
    [KF-MapName KFMapSummary]
MapName=KF-MapName
ScreenshotPathName=UI_MapPreview_TEX.UI_MapPreview_Placeholder
Managing these files manually is prone to syntax errors. We strongly recommend using the WebAdmin GUI:
  1. Log in to WebAdmin.
  2. Navigate to Workshop Content.
  3. Simply paste the Workshop ID and click Add. The system will automatically update both of the .ini files mentioned above for you.
