Shipment or Killhouse for the Small maps (MP5 pwnage there, otherwise AK47 ownage hahaha
)
In those two maps, its so easy to start stacking Air Support and Kill Streaks.. once I got to 49 w/o dying (in FFA) and I ran out of ammo and everybody gangs up on me... but after that, after I get the Helicopter's 7 Kill Streak, I just do suicidal stuff; aka super charge or Jihad Super Bomber and then start again
