IMHO, probably the best shooter ever released in a long time. I would highly recommend this one for anyone who hasn't already purchased it.

I have 2 accounts now, my main which I usually stay in silver and my sons smurf account which is in the 3600 range. The gameplay between masters and even platinum is so much different. In masters you see very few trolls and it's like everyone knows just what to do. The only way to move up is 6 stack with some great players that all have a common goal and play the objective.
