I was wondering what people meant by scripts, I thought that scripts were pre written files that I could download. Thank you for clarifying that I must write them myself. So what you are saying is that I cannot create coops missions like the ones in single player without writing my own code but I can create simple clear and advance missions like the ones in multiplayer?

I bought the game off of steam and am very interested in creating COOP missions but the in game editor seams to lack some features. My question is am I missing some vital or important files that I can download from somewhere? In advance, Thank you for replies
