I have a 0.38 kd in mw3 any advice some one can give me?

is aim assist on? try lowering your sensitivity, play smarter and don't run in the middle like a psycho.

quit and play battlefield 3 because that game takes skill to do well instead of pure luck

best advice : get a life

I quit playing MW3 becasue their maps, spawning, and weapon damage sucks.

Really just find the most Overpowered weapon in the game. Move slowely along the outer edges of the map, and camp in the corners every so often.

Play tactical, get sitrep pro, then you hear the enemies footsteps better, that it usually what gives me an advantage in close-combats

Use Stalker.

get a better game.
