Current questions and answers regarding the map editor.

Please explain in more detail. I'm just a beginner in map creation and might not understand. I really need help.

Create any multiplayer map. Save it. Open the map file with an archiver. Copy all the files from your old map (from the Singleplayer scenario folder) into the folder for the new multiplayer map. Save it. It might work, or it might not, because it might need to rewrite something in the files themselves.
