I'm really trying to get a Skullmasher Sniper Rifle and an Infinity Pistol. lvl. 50 for both. I played for like 4 hours yesterday killing Doc Mercy to no avail. And from what i have heard its almost impossible to get the Skullmasher since it seems to be glitched a bit, I hear unless you catch it while its falling it will fall through the floor. So any help on some duping those for me that would be awesome.
