Pros: - There are 3 chapters to the game and Chapter 3 is where this add-on really shines. It consists of a rather clever set of puzzles to illuminate orbs that unlock your path to the final combat arena. - Download code that I purchased on Amazon works on my game which I originally purchased on Steam. You just need to enter your code into the main Steam control panel.
Cons: - Chapters 1 and 2 have you wandering through largely the same landscape as the previous game. - The final boss is pretty brutal unless you happened to have Propp's Party Plasma collected in Chapter 2.
Overall an excellent add-on pack. For the original sale price it is a bit expensive for what you get. But at the discount price it is very reasonable. Looking forward to more add-ons.
