I was playing control once and this titan threw up his dance bubble to protect himself and 2 other allies. I ran and slid into the bubble and used my fist of havoc to take them out and was successful at killing them all except for one. I emptied my entire shot gun into him on full auto mode but he wouldnt die. I got mad because I thought he was cheating, threw out my grenade and began bobbing and weaving as I continuously punched him. But he wasn't even fighting back which pissed me off even more. Then I got the message " you have captured zone b" Turns out he was my team mate.
