I don't know why this game is so unerated...
All the other fighters in the game are very original, from a mass of clay that can shape itself to box gloves and broken bottles, to an evil Santa claus, it even uses some very original characters from other games: Earthworm jim and Boogerman.
Now trough some of the moves of the game are parodied of other fighting games, most of them are very original, say all of Blob moves are unique thanks to his morphing ability, and the gross way Sumo santa uses his massive fat to attack.
I didn't find anything wrong with the background graphics, they are o.k, but definitely they aren't bad, and the characters models are just impressive, and it's a fresh mode to do characters from any kind of game, so the game looks pretty unique, I didn't find anything to complaint abut the music either, in fact its very original comparing it to the music of other fighting games.
Now,the story of the game and it's characters it's the worst part of the game, all of them are ridiculous and doesn't make any sense, so you'll not be encouraged to finish the game multiple times to see the endings (which are nothing but text), the game doesn't even have anything interesting to do after you unlock the 3 secret characters, but the lasting appeal of the game is it's multiplayer of course, like any other fighting game, and the game it's so original that you'll want to play the game whit other friend for a good while.
So this concludes my review of this so much underappreciated game, I hope I'm speaking well for those few people that still appreciate this wonderful game!
