MaximusHost can save Steam Workshop subscriptions for Killing Floor 2 items that support dedicated servers. A subscription is a request for KF2 to download content; it does not prove that the item is compatible or installed.

Add a Workshop item

1. Create a backup before changing subscriptions on an established server.
2. Stop the server and wait for the stop operation to finish.
3. Open Mods.
4. Paste the Workshop item's numeric ID or its Steam Community Workshop link.
5. Choose Add Workshop item and confirm that the subscription appears in the list.
6. Leave an installed stock map selected as the starting map, then start the server.
7. Wait for startup to finish. Refresh Mods → Maps and confirm the map appears as installed before selecting it.

KF2 downloads subscribed content during server startup. The Mods page lists subscriptions but does not show download progress for each item. If a map is still missing after startup, check Console and Logs and the Workshop description for dedicated-server requirements or dependencies.

Remove a subscription

Stop the server before removing a Workshop subscription. Removing it changes the subscription list KF2 uses on a later start, but it does not delete files already downloaded. Remove the map from rotation separately if it is there. Avoid deleting unfamiliar files from Files.

Check compatibility

• Choose items that explicitly support a dedicated server and the server's game version.
• Some items depend on other files or work only in certain game modes.
• Client-only items, unsupported server files, and mutators may not work. The panel does not activate mutators.
• Steam Workshop files are not available to Epic Store players. Use stock maps if Epic players need to join.
• MaximusHost does not provide per-item download progress or a control to force an individual Workshop item to update.
• Keep a stock starting map selected until a custom map is installed. Choosing a missing map too early can prevent startup.

When the map appears in the installed list, follow Maps and map rotation to add it to the rotation or choose it as the starting map. If the server does not start, see Troubleshooting.
