There are some unlockables present in the game – mainly more characters – but as with the fighting-style itself, there simply is not much depth to it. With more characters, more stages, a better story, and far better graphics, it's tough to imagine that anyone wouldn't rather play Super Smash Bros. Brawl over Teenage Mutant Ninja Turtles Smash-up. Or, at the very least, they would have to be far more nostalgic for those pizza-loving heroes in a half-shell than most people. But, this game does come with a TMNT mini-comic book.
