when on the pit especially in lonewolf, grab the sniper and a brute shot and go to either one of the towers (towers are where you can sometimes spawn up top) then go to where the br is on the wall closet to the back of the map(gate and over shield area being front of map) then right next to the br spawn look down and jump and shoot your brute shot three times. you will lose all shield but make sure you grab the health gen too
