Call of Duty: Modern Warfare 2/Body Count

Strategy
One good two-person strategy is to run to the back, through the kitchen to the back alley with the trash bins and head to the left past the wall. Head towards the back of the building in front you. There will be smoke usually, but there won't be anyone there. Go through the smoke and head to the alley behind the building. Now is a good time to sprint. Watch the left door as you come through the smoke. You and your partner can watch each side of the alley way and accumulate as many points as needed.
