just a tip, during the reload phase, spin your view to look away from the turret; this will allow the engine to cleanup the dead bodies, and get rid of the lag after each clip.
also, this DOES work unattended(for ALOT less points), but the placement of your teammate is crucial. i have found that by putting him on side of the server cabinet closest to the bomb works consistently. then you move behind the server cabinet and look at the wall of servers so you are protected from fire and not looking at the turret. if your teammate makes it 1 minute killing the guys on the turret, then he should be good forever, or until your xbox dies
