Hi, i know it is a couple other posts out here who are looking for the same thing, but i figure they have done it and dont care anymore 
Anyway, looking for 3 people, my psn is mrjoggy, add me and add in the friend request that you are looking for the trophy yourself (or just wanna help a struggling vault hunter out)
Live in central europe. Can do it as soon as we got a group of 4 people!
