Ok I am farther along now. I can edit a pc campaign mission ex( 04MontignacMustFall.Eden.pbo) for more players to be playable in the squad then stuff pbo it up and inject it into the mptemplates folder on the xbox and choose my mission, new mission then it will be in a blank space in the editor as long as i choose the right island it loads ignoring the warnings of no unit, default island etc then try it then save it. But the catch is you can host the mission but everyone connecting needs the whole mission not just the server download or they will get no sound because it is missing in the mptemplates folder.
1. unpbo the pc campaign into your user/name/mpmissions folder on the pc game
2 start opf pc then go to multi player then open the editor choose a island and mission add more playable units in the squad. preview it then save it with the same name.
3 stuff pbo the mission using the same name.
4 ftp into your xbox opf folder MPTemplates.
5 Start ofp elite then choose my mission, new mission then choose the blank text area and begin remember to choose the right island but ignore the unit not chosen warning etc and begin you'll have the whole script waypoints etc just like in the campaign but with a few friends along for the ride. they'll have to have the mission in their MPTemplates as well to get sound. Still working on it. Any help would be welcome. I will keep working on it to figure out more like how to get the injected missions to show text in the templates menu.
