IGN: "Like I said, there's really nothing particularly bad about Teenage Mutant Ninja Turtles: Smash-Up (well, except for the dreadful Arcade Mode cutscenes). It's a fun, frantic fighting game that has a solid foundation. That foundation -- and I know I'm sounding like a broken record at this point -- is Smash Bros., and the designers don't make any effort to hide from that fact.
The game does a good job mimicking the classic fighter with TMNT characters, but in all honesty the game really just makes me want to play Smash Bros. instead. Smash-Up is a good game for those that really want a decent TMNT fighter, but it doesn't do a whole lot to make it its own experience."
