I used to create missions, but that ended after I player MP7 Mine Sweeping. Wow, I don´t remember who made that one, but he is way ahead of me. I looked at its design, well, it´s similar, even better sometimes than those of the Campaing or the Single Missions.
I think there´s 2 kind of missions: Those simple (like mine) and those great, memorable ones, but there´s a HUGE
gab between them, and there´s nothing to show you the path....
Maybe a tutorial, guide, hints...?
