BlitzPig_Frat replied to 169th_Ice's topic in Digital Combat Simulator Series Mission/Campaign Buildinghow goes the tutorial, is it done? I've been looking for a good one, no luck yet. Anybody know how to make a MP COOP mission work? Like the specific settings that makes it COOP. I have made a few really detailed mission but when my squadmates try and connect, the "join" button for them to pick the coalition is not enabled. Any reason why? I have all the plane slots there, and they show, just the join button is not working for them.
