163-9 this early seems a little fake though. Hell my highest in all the time I played MW3 was 80-5 so not sure how you doubled that the first week of this game. Unless your killstreak setup was Lodestar, Dogs and Warship I have no idea how you'd do that well. I'd be more interested in seeing the enemy teams' scores.

56-8. On Hijacked running Hellstorm, Lightning Strike and Dragonfire. PDW rapid fire oh and I picked up someone's M8A1 and it is BEAST.
Helps I had a 4 bar and the enemy had level 2 splitscreen players. So it was basically like boosting lol.
I am honest though. I know most high kill games are 30% your individual skill, 20% your team's individual skill and 50% how bad the other team is.
