Jeez...what's with all the camera following the bullets bull(et)shit? Bullet time was cool in Max Payne and the matrix, but if it's with EVERY FRICKING KILL you make, it gets gimmicky fast.
[sarcasm]Using a machine gun must be swell in that game. And multiplayer even more ("everyone in the server wait up...we've got to show a fatality deathscene to some camper").
Personally, I've never been a fan of sniper rifles since playing CTF-Facingworlds back in Unreal Tournament (on most servers, I was the only guy who did all sorts of controversial stuff like trying to get to their base and take that flag-thingy).
