TMNT IV is a side scrolling beat 'em up, and in general I think these games are pretty lame, all you do is hit the same buttons over and over again until you kill all the baddies and get the arrow that says you can advance to the right. And that's basically all this game consists of, but TMNT IV manages still to keep me playing every once in a while. It's a really great looking game, with some cool effects (I love throwing the enemies at the screen!) The turtles look great as do the environments, and the time travel aspect of this game means we get to see more variety in the levels. This game is pretty mindless, but that can be a plus when you just want to get out some aggression; I have the most fun when I hook up my Fighter Stick and can just bang away at the buttons. It makes killing foot soldiers so satisfying. Of course, it has 2 player co-op which is how most people would want to play this game.
