A great that idea gets better as you play........... Literally!
The sound work is wonderful, and the graphics are top of the line for a DLC only title on the Xbox360. Even kids will enjoy this game, as it's fun and has classic platform elements mixed with shooting controls that are both easy to use and fun to take advantage of.
Theres not much bad I could sight other then some some times frustrating puzzles that when you finally do figure them out you want to slap your self on the head for being so stupid.
All in all this is one XLBA title that no Xbox360 should be without it's rock solid game play, epic final battle, and wicked fun factor make it a perfect way for people to see the best of the best on Live without blowing crap loads of cash.
