That said...I was amazing at MW2, I frequently beat out supposed "MLG" players.
My Weapon of Choice? The Riot Shield and a Throwing Knife, never failed me in Search and Destroy.
I'm glad I'm not the only one that did this.
At one point when I was still play MW2 I was able to get an organized group of riot shielders going. We were able to make a phalanx out of riot shields, we each got one kill and hid in a corner all of us huddled together. We won, they never thought to use an RPG on us once.
