Thank you very much for the information. I have extracted many tools from Heroes Unleashed as you recommended, and it's fantastic!
Combining the information from the forum and the help I received through Discord, I have managed to create a small map for SOAF. I can run it, roam around, shoot, and even place some enemies. I can run the map in Mission mode, but nowhere else. The problem is that I don't know how I can configure the map for the Shootout game mode or prepare it for team-based multiplayer or free-for-all. I've been searching for a guide on this, but so far, I haven't had any luck.
Does anyone know how I could configure a map to make it available in Shootout mode and team-based multiplayer or free-for-all?
Considering that SOAF and Ghost Recon are almost the same, I suppose the configuration for one will be valid for the other
