My favs are 1v1 Lockout. I usually get Smg/Handgun, I take the sword usually but don't use it, cause I'm less than average w/ sword.
Usually I do pretty good 1v1 Ascension, just own w/ whatever I've got, unless they have rockets or are good w/ sniper. I have a hard time dodging rockets, unlike EVERYONE I shoot at w/ a rocket. A good sniper owns all on acension especially if the move from spot to spot.
Midship I LOATH!
Beaver creek/rumble pit/handgun,smg. Try to stay out of the middle mainly, run in and out of tunnels over/around bases.
Foundation I usually fair pretty well. Dual smgs, just cause they are readily avalible. I usually don't go out of my way for a weapon. Don't know if thats bad or not.
I don't do the big levels much cause I hate being sniped and I can't snipe well at all, plus I don't play Big team battle...
