I'm going to try the impossible (or so it seems) Im going to add build mod for bfme1 to maps, so it won't say you have diffrent version meaning on certin maps you can build like in bfme 2 in bfme 1. I must say im total noob, i will try my best. Just like let ya know. Far as i know, no one, and i mean no one has tried this.
No one has tried this im sure of that, whatever happens good luck with it, post all your updates here!
