After grinding for what seemed like forever, I was finally able to get another Exotic weapon in my repertoire. So that makes the MedVed shotgun and the Liberator. The Liberator is one of those exotic weapons that when paired with its pistol counterpart, it gains a set bonus. Forgot the name of the pistol and what the bonus was, but it made me decide I would get them regardless. Now to grind to get 1331 Phoenix credits 4 to 5 more times to get all of the ones I can purchase.
