Beat the game on normal. Like what I've heard, this game is missing something that made the SNES game awesome. It's still fun, but missing something.
The Super Shredder killed me once or twice, before I realized how easy he was, all you have to do it stand in place, and attack, Shredder will walk into your attacks, and after you hit him a few times, move to another place and do the same thing until he's dead, easy.
If anyone wants to play for achievements, or just to play, let me know.
