I play on both XBOX Live and PSN. I learned the game on PSN and have a 2.5 K/D on that network, so when I went to play on Xbox Live with what I learned my K/D went up. On Xbox Live my K/D is 3.0. It is not easy to keep as just 1 bad game knocks my average down and takes several good games to bring it back.
I am surprised that my gameplay has progressed to this point. Back when I started playing COD multiplayer with Black Ops 2, I didn't think I would be able to play the way I do now. I remember when I first started playing I sometimes wouldn't be able to identify if a person was an enemy or ally, and my aim was terrible.
