My load out: Atheons epilogue Swordbreaker Corrective measure Honestly, I got 90% of my kills with swordbreaker. Just don't run large maps (I backed out of every sky shock and bastion game) and play normal sized maps (my favorites were twilight gap, shores of time and blind watch) and just camp corners and go slow. Follow teammates to help have a distraction for enemies and keep at it. Got it done in about 10 games. I thought I would never get it but that shotgun was amazing!
