Map: Crossfire
Location: On the roof of the high-rise
A bit more of a tricky one this, but the pay-off is worth it. Head over to the three walled building with chair and cooker on the first floor. From here you can either use the chair, as in this video, or the cooker as your launch platform to reach the next level. Then simply jump your way to the roof and wait. This video goes on to show you how to actually leave the map but, as there’s no-one else out there to shoot at it’s pretty pointless, so stay on the roof andbuild upthose kill streaks.
