Yeah me Sirrfurr and RadialArm were taking it to some guys. I have a 9 ranking so far trying to get in those double digits. My advice to you guys to improve your stats is to:
-have a plasma rifle in your left hand, and a submachine gun in your right.
-Never pick up the needler, your just askin to die. It's better to have a submachine gun and throw grenades until you can find another submachine gun or preferably plasma rifle.
Halo is basically a game of paper, rock, scissors.
Up-close:
Shotgun beats anything (except plama sword)
Submachine gun
beats rifle
Distance:
Sniper
beats mostly anything
Rifle
beats submachine guns
Short distance:
Rocket launcher
beats anything (if in hands of skilled user)
(lh) plasma rifle (rh) submachine guns
beats dual submachine guns.
(lh) submachine gun (rh) pistol
beats dual submachine guns
(lh) submachine gun (rh) pistol
tie (lh) plasma rifle (rh) submachine guns
If you stick to these basic rules, you'll do well; I'm always in the top 3 in the game, mainly because I'm good at paper rock scissors.

You know your good when people start announcing your name like "Oh shit Lex is coming, Lex is coming", or when they say "Hey I killed Lex, I killed Lex". I love my fame.
