I would have to say my favorite thing to do is Knife people with the normal melee attack and the throwing kinfe. I am not a huge fan of the Riot Shield, for it makes you easy to kill. I also love to use the Sniper Rifles. There is nothing better then knowing where the opposition is and Sniping them so they are pinned down. That gives your team the ability to be able to spawn kill the hell out of them. Also yesterday I snuck up on a Sniper and Throwing Knifed him and then i saw his Tactical Insert and when he spawned I did it to him again, lol. The same match I threw a Knife at a Sniper he ran away not getting killed but his team mate got killed then i kinfed him too lol. I love stealth killing.
