This game is a little difficult to talk about. I personally hate when good games that have ridiculous final bosses, and Unleashed is one of the prime examples of that.
All daytime stages are great, some of my favorites boost stages from the franchise are in this game. Werehog isn't all bad either, but with extremely long levels, some of the last few are very painful to complete.
But the final boss is ridiculous, janky and insufferable, and it made my appreciation for the game drop a bit.
