why not colllaborate with one of the guys who really make these weapons ,and add em into x4 , then x4 =mw2
for all extreme users..
after all , there are other mods out there (not as good as extreme) who have collaborated with modders who have made these weapons..
they wouldnt need to give their weapon raw files away , just let em add into x4 and release it as a stand alone x4 mod.. with extremes support..
