It is a pretty beefy XBLA release with a decent 7 hour campaign and a bunch of bonus challenge rooms that can be tackled over Xbox Live. I was only able to beat two of the nine challenge rooms on my own and I am under the impression the game did not sell terribly well because even letting custom match sit idle in the background on my 360 for quite a while no would join my room. So if anybody else has this can they please give me a friend request so we can knock out the rest and get some gamerscore?
