One good game solo. Even better multiplayer.
Gameplay: Just like a Ultimate Ninja game, a litttle different is all. Graphics good for a PSP game too. Specials good and short I like that 'cause I can get right back to the game.
Story: It's story can get a little confusing a bit(also keeping it from being a 10). If it was a little more free roaming I'd never put it down, story goes pretty far too (don't wanna say any spoilers doe.)
Sound: Ehh sound could've been a bit better, but overall it was just fine.
Overall: 9.0-10 This game is freaking sweet I promise you. Rent it to find out, or trust me and buy it.
