I've been looking everywhere for saves to get the Motorhead and Obsessed achievements. I already beat the DLC and got the achievement for that and when I went to do the motorhead achievement it never popped up for me and i really dont want to do those missions again... I was able to find two save sets online for the campaign of carnage but one was for pc and the other was for ps3.
I believe Obsessed is save to your profile. For Motorhead, did you do all the levels of side missions? Think there's 3 each. I haven't read or seen that the achievement is glitched anywhere. I was going to make a save set for that dlc but never got around to it. I did set one up for Motorhead though. Let me see if I can find it. I'll upload it in a few if I can.
Man that would be awesome, i was wondering if it was something saved to your profile, but when i saw the save set for ps3 on nextgen i was like maybe there could be save for it http://www.nextgenupdate.com/forums/playstation-3-trophy-mods-cheats-guides/605309-borderlands-2-mr-torgue-s-campaign-carnage-dlc-save-set-2.html
