I bought "Mutant Melee" because I wanted a cheap Ninja Turtles game to give me some nostalgic thrills, and, to a certain point, you get this in this game. Based on the recent (2003 onwards) cartoon series, Melee sees you play as one of the many Turtles characters through a series of challenges, or, if you choose to go for the multiplayer melee mode, you can play mini-games or just kick the shell out of each other.
In terms of graphics, this game is pretty good by PS2 standards. I actually think the characters look great in their cell-shaded 3D forms, and the backgrounds aren't bad either, even if the camera angle is static, and sometimes pulls out too far to allow you to see what you're doing.
This game is unfortunately let down by repetitive missions and tricky game play. The missions range from being ridiculously easy to frustratingly hard - and it's not so much about skill as rapid button-mashing and good luck. (And stress levels run high when you simply can't get a move in edge ways!)
The game makes up for some of its trickiness by allowing you to play a good variety of characters in the melee battles, and a fair few are unlockable in the single player adventure mode, too (all complete with original voiceovers). Plus, since we live in an age where we expect additional extras, there is plenty of unlockable content, which includes comic book pages, character biographies, silly but fun animated out-takes, and Turtles toy photos.
I think if you're a hard-core Turtle-head you'll find something to enjoy in this game - even if it's simply the buzz of playing as your favourite character in locations that are familiar to you - but the game is unnecessarily tricky, disappointingly unoriginal, and I doubt that it'll have any replay value.
