How To Add Custom Maps To Your Killing Floor Server

Killing Floor has hundreds of community maps. Here's how to add them to your server.

Uploading Custom Maps

  1. 1
    Download the map and unzip it on your computer. You'll usually get a .rom map file and sometimes extra files such as .utx, .usx, .uax, .ukx or .u.
  2. 2
    Log in to Bropanel and Stop your server.
  3. 3
    In the sidebar, go to Files.
  4. 4
    Upload each file to its folder:
    • .rom files go in Maps
    • .utx files go in Textures
    • .usx files go in StaticMeshes
    • .uax files go in Sounds
    • .ukx files go in Animations
    • .u, .int and .ucl files go in System
  5. 5
    Start your server.

To play the map, enter its name in Map or pick it in Web Admin.

Note

Players who don't have the map download it when they join. Your server sends custom files through fast downloads automatically, or you can use your own download redirect.
