Difference against the Hammer Buster I
It would seem so far that the only differences between this and the Hammer Buster would be the name and unique text; does this alone warrant a page? That said, it's been just over a week, so there may be more differences discovered in the future. This space will be used to discuss this point, but for now we'll leave it.

The Pre-Sequel takes place before Borderlands 2, right? So that means that, in-universe, the Hammer Buster II was available before the Hammer Buster.
