hello there I have been playing arma for quite a long time in multiplayer, but now I would like to be able to create my own missions and put in my own stuff. For example I would like to know how to create a map warfare with predefined starting location for the bases. I would also like to put myself the money of the beginning And some cities already under control of a camp And I would see myself for the rest, if anyone knows how to do or, has a link to a good tutorial that explains how to do it,it will be really cool Cya
