Use Mods → Maps to see map packages installed on the server. Use Properties → Killing Floor 2 Settings to choose the starting map and manage the ordered map rotation. A map must be installed before it can be selected.

Install a custom map first

For a Steam Workshop map, add its subscription while the server is stopped. Keep a stock map selected, start the server, wait for startup and downloads to finish, then refresh the Maps list. The item may be subscribed before its files are installed. See Install Steam Workshop content.

Add an installed map to rotation

1. In Mods → Maps, confirm the map is marked installed.
2. Choose Add to rotation beside the map.
3. Reload the server's Manage page if the settings list does not refresh.
4. Open Properties → Killing Floor 2 Settings and select the Starting map you want loaded next time the server starts.
5. Arrange the rotation order and keep at least one known-working map active.
6. Choose Save for next start/restart. If you want to apply the changes sooner, choose Save & restart now while the server is running and you have permission.

The starting map is loaded when the server starts. Rotation controls which maps KF2 can cycle through during play; changing the starting map does not replace the rotation list. Settings changes require a start or restart to take effect.

Remove a map from rotation

Choose Remove from rotation beside the map. This removes it from the managed rotation but does not uninstall the files or remove its Workshop subscription. To remove a Workshop subscription, stop the server and remove it in Mods. Already downloaded files may remain.

If a map is missing or fails

• Confirm the map appears as installed in Mods → Maps.
• For a Workshop map, start on a stock map and allow the download to finish before trying again.
• Check Console and Logs for map-loading errors.
• Confirm the map supports the selected game mode. Try a stock map and common mode to isolate a compatibility issue.
• Steam Workshop files cannot be downloaded by Epic Store players. Use stock maps for a mixed-store group.

Create a backup before changing an established map rotation. A map may load in one mode but not another, so test custom combinations before scheduling a full group session.
