Summary: The game functions properly, but its absolutely frustrating. the controls are very basic and feel behind. The camera isn't far enough away from your character to be able to dodge all the random objects flying out of nowhere or the random ninjas that just materialized and sprinted into you for no reason. There are so many boulders and other crap its just annoying. The sound is the absolute worst part.
Summary: When first playing this game I was impressed with the extras it offered. You can choose from a wide variety of characters, each with thier own unique skills and fighting style, and the audio and graphics aren't too bad either. The only majoy dissapointment I had with the game is entirely mini games. You can unlock cool abilities for each character and it can take a little stratagy to think of how or which character to use for each mission that you choose.
Summary: This game has no direct storyline, so it sucks! why would they make a game that has no storyline I don't get it, if you got the second one and are expecting a game that is just as good or better you will be very disappointed in this one. I recommend only if you are really bored and don't have anything better to do.
