I just got this game along with House of the Dead: Overkill for the reduced prices at Newegg, and so far I'm loving both of them. I had heard that MadWorld is ridiculously short and easy, so I downloaded a completed game save file and started out playing the game on "Hard" mode (which for some idiotic reason is locked until you beat the game on Normal), and I've found the game to be quite thrilling and occasionally hilarious. (HOTD is also a lot of fun, by the way, though extremely easy once you get the shotgun and upgrade it a few times.)
