You'll find the Insurgency: Sandstorm map-making quick guide here: View guide

Like TFE, Insurgency: Sandstorm uses the Unreal Engine/Editor.

Existing custom maps can be found on the mod.ui site, here: View custom maps.

You can subscribe to any maps on this site and they'll automatically download to the game once you log in.

Custom maps on our server will also auto-download, like mods.

Check back here for new MFH Insurgency maps, soon.
