yeah i play on 10, holographic for the newbz, it locks on targets easyer and follows them etc, which is pretty cheap but meh, whatever gets you the kills, ive done a full prestiege with intervention, nearly on 1000 headshots, lvl 55 or summet 5th prestiege, for smgs i used to use vector, but i dunno i went off it, ump45 or mp5k are pretty fun to use, although ill probs be sticking with intervention from now on, such a fun/hard gun to use
