I am totally addicted to this game. I'm in the top 20K in the world for straight kills (PS3). I play domination and not much else. Anyone else play? Perhaps we could all meet up and kill each other? Or form a clan and kill everybody else?
I too am what can only be described as addicted to this game (360 version). I think I derive just a bit too much satisfaction from a perfect sniper headshot.
And it's true 5.1 adds a massive amount to the gaming experience.
I'm on Call of Duty quite alot on the 360, my gamertag is Choppy Balboa if you want to add me. You really have to play this game using headphones, although you don't get the surround sound, it does sound amazing.
