1UP: 91
The design constraints of Nintendo's system forced the developers at Platinum Games to be creative, and they followed through on their creativity by putting together a thoroughly enjoyable brawler with just the right amount of the ultra-violence.

Dark, brutal and hilarious in just the right way, MadWorld is a title that has rocketed to the top of every staff member's must buy list. Don't let the fact that it's on a "kiddie console" fool you-this is one title every "hardcore" gamer needs to play, provided you're over eighteen years old, of course.

I realize that not everybody will find MadWorld's unique visual and aural presentation appealing, but to me, the game is an instant collector's item and a Wii showpiece, not just for its amazing style, but for its label-busting content.

Nintendo Power: 90Although the game is unquestionably brutal, the violence is so over-the-top that it's more humorous than gruesome...For any hardcore gamer, this one is not to be missed.

IGN UK: 89
Control issues hamper fluidity but there’s no denying that, with some investment, MadWorld rewards in huge doses, delivering an incredibly visceral experience that's as stunningly unique and obscenely entertaining as it is just plain obscene.

Madworld has made a lot of noise before its launch and, after playing it, we can say it deserves it, although the result could have been even better. The game brings very special aesthetics which are undoubtedly a good decision, and totally fits the gameplay experience Platinum Games wanted to offer.

Computer and videogames: 80
A bloody, entertaining - but short-lived - action game.

Meristation: 80
Brutality, tons of blood and the most violent show ever seen to come exclusively to Wii. Former Clover members prove their talent with this beat'em up portrayed with this comic-book look drawn with black, white and red colors. Modern art with a great sense of humor mixed with a macabre tone, MadWorld can only be blamed for its 6 hours campaign and the little depth it offers as a brawler, compared to the biggest games in the genre.

Eurogamer: 70
No matter how much the schoolboy-humour commentary grates, no matter how repetitive the bits in between the set-pieces start to feel and no matter how frustrating the later levels become, MadWorld provides a rush of blood to the head almost as often as it provides a rush of blood to the pavement.

Sony Defense Force: 0
No HD graphics, no AA, no online, no siaxis support this is the most shittiest game ever!
The Wii cant support colors or what?
I mean black & white? We are in the 2009 people!
Please save your money and buy another game like Killzone 2
