Just confirmed by Helios, there will be no mission editor for creating and swapping missions for console OFP2.

Hi everyone,

I can confirm that there will be no mission editor for creating and swapping missions for console versions of the game.

The PC version however will have a mission editor allowing people to create their own missions. We’ll bring you plenty of information on this feature as development progresses.

If this changes in any way I will of course let you know.
