Stop playing Team Deathmatch, ALWAYS use assasin & supressor.

Go to domination & camp a flag, if this is your first COD. You will not have a good KD until a few MONTHS on gameplay, Just ENJOY it. and practice to get a good KD in BOPS 2.

The biggest thing wearing you down (and same for myself to an extent) is using the riot shield so much. It can be fun, but that's probably why your KD is lower. I was wondering how you don't have hardly any other attachments, but you hardly have any kills outside of the riot shield.

Playing more helps a lot, and using UAV, Care Package, and Pred missle with hardline is actually great for boosting the KD. The assault strike package gets you more kills than just your gun.

I would suggest trying Team Defender, since it can give you an idea of where people will be gravitating towards. It's one of my personal favorites.

I have dedicated the game to shields only, unless I pickup a weapon for some reason. I will stick with the shield.

I see a few issues. One has been stated already...the riot sheild. While it can be fun it is not very practicle. I will try to keep it short on the other things I think you could change. Others may not agree with me, but I will show you what I have learned and what has worked for me.

On SMG's...you don't need quickdraw. They aim in quick enough. That way you can use a different perk while using those weapons. You don't need stalker on SMG's either. Since this makes you move faster while aiming it can also make you less accurate if you don't aim well to begin with. These two perks work better with assault rifles and LMG's. (IMO)

As far as your killstreaks go, I would go with Care package, predator missle, attack helicopter. (with hardline...that way you get them at 3,4,6 kills) So many players run with assasin that the UAV is almost pointless. You also have an empty slot on you specialist set-up.

If you insist on using the riotshield use overkill. That way you can use a better weapon.

I would also use the semtex over the Frag. I think the semtex is stronger than the frag in this game. As far as weapons go, jsut use what your comfortable with. I notice you have only played for 24 hours, this usually isn't enough time to learn the maps really good. (At least for me anyway) So good luck in your efforts and have fun.
