Re: Leviathan's Arm
I have read that it is still there virtually, even though you may not see it. If you can remember how you previously did it, you can do it again if you can line yourself up correctly between 2 points while walking across. However, you may need to use another exploit to actually get into the Treasure Room. But if you just killed it, the door may already be open. I believe you can find it on YouTube under Borderlands2.
