Okay i didnt know where to put this so....
Can one of you take a SP map and take out the SP stuff to make it MP
I believe some people already did something like this. Why dont you attempt it yourself?
Yes it's possible to do that. The main things you need to worry about are pawns, factorys, and anything else AI related.
because im right now trying to take a map from America's Army and put it in RC
yes this has been done, both me and agentsmith can say it does but it probably easier to build one from scatch
