I've currently got a 7.95 K/D, played about 9 hours or so, And like a few others said you can not play this like a CoD game, It just doesnt work. I little advice on racking up kills...Dont bother. When you start this game you want to get used to how everything works, and i mean properly lol How bad recoil is, whats the max range you can/should use an assault riffle, when to know that your getting a bit too close to the main combat(when your sniping) and so on. To start with you want to hang back and wait for them to come to you, dont try and rush them and dont try to engage more than 1. If you see a loan wolf try to pick him off and move to a different cover, the key to this game seems to be you cant stick in 1 place for too long because people seem to hold grudges and after you kill someone they will come looking for you! so keep moving after every 1-3 kills. Also using the rite weapon/attachments on the rite map is something your going to have to do. If you try a map using a sniper and it doesnt work out too well then the next time you get that map try a different approach and vise versa. I myself use sniper with a short scope 24/7 no matter what the map, and running and gunning (for me anyway) seems the best option for snipers, because if you sit back in a nice little camping spot you will eventually get picked. Theres not realy much anyone can say to help you out, it just comes with practice. Dont get pissed if you go 2-10 because hey, who cares? i certainly dont give a *bleep* if i have a bad game, i just see it as a incentive to do better in the next match lol.

If your on PSN add me, my PSN is A_C_I_D_Y and if you need to know anything and need some tips just give me a shout =D
