How To Change The Map Rotation On Your Natural Selection 2 Server

Your server moves to the next map in its map cycle once a round ends and the map time is up. The map cycle lives in MapCycle.json.

Editing The Map Cycle

  1. 1
    Log in to Bropanel and Stop your server.
  2. 2
    In the sidebar, go to Files.
  3. 3
    Open the config folder (config_combat for NS2: Combat) and click MapCycle.json.
  4. 4
    Edit the list of maps, then save the file.
  5. 5
    Start your server.

Here is an example that plays three maps in order, switching after 30 minutes:

{
  "maps": ["ns2_summit", "ns2_veil", "ns2_tram"],
  "mode": "order",
  "time": 30
}
  • maps is the list of map names. Don't list the same map twice when mode is order.
  • mode is order to play them in turn or random to shuffle them.
  • time is how many minutes to play a map before switching, once the round ends.

Workshop maps go in the list by name too, as long as their mod is in Workshop Mods. Admins can switch maps right away with the sv_changemap console command, for example sv_changemap ns2_veil.
