for all intents and purposes I can think of you can make a MP behave like a SP map.

I was interested in making a CoH2 campaign map. Of course I wanted to screw around first befor starting something for real.

Just some ideas
But I want to decide with coding what the AI is doing. This will be very intensive part in coding, I know. But I would like to give it a shot
I saw this is possible with Lua. I couldnt try out anything yet, but if you could help me a hand, it would be greatly appreciated!
