Review according to purchase from Target:
Well, to begin with, in case you don't know, Bionicle is a sort of monster-machine toy that Lego makes. This is the first Xbox 360 Bionicle game that has been made.
So, you start out as Jaller, the red Bionicle. You go to start a level and as you progress you find different masks throughout the level that can change you to one of the other Bionicles of the, (at the time of the game's release), current generation of Bionicles. (The Bionicle series has been going on for some years now and has different generations or series.)
The fact that you can change and regain masks throughout the level makes it VERY hard to fail. Because, once you run out of life, you lose a mask. But, you can just go find the mask again in the level and continue. It's impossible to have no masks available at any given time.
There is also a feature where when you collect enough cogs, (Lego game currency), you turn into a gold Bionicle that can complete a certain obvious task that is required in order to progress through the level.
There are cut-scenes, as in every Lego game, but they're all so Lego stereotypical. The characters grunt and often take part in somewhat humorous activities. The music is not great, but not obnoxious. It's on the brink of being calming and being repetitive.
Well, overall it's a rather fun game, but your money is better spent on one of the many other Lego video games.
