This game builds on the origional in the best way possible. All the mechanics are better, the guns now upgrade with use, and the worlds are excellent to explore. I can not bring myself to give this 4 stars or higher due to the PTSD I developed while traversing Grelbin. The final boss also fell short to me, I would have enjoyed an epic battle with Qwark after all the setup, but a giant protopet was not the conclusion i had hoped for. Not as good as the first games ending by a long mark.
