well to kill the prickits in the Gates you want ful elite engiens on 1 fig with all shilds on the drones.Now ive done is try to fly over the pack click lock and run at the same time.
then come back and move backwards and drag them from one side of the map to the other till they pop or run.If they run from you just let them and lock on another one.They will park them selfs in the corners.If you try to death run with them they will beet you down and you have no time left to heel up for the next one.So let them run and park.once you have parked them all then go and kill them dont sitt there to long on them dont forget theres more then one there so click and drag agen one at a time.
Good luck happy hunting
