This game is soooo cool! It is the fastest loading game for Playstation that I have ever played, the graphics are the best too.
I would buy it if I were you, but it might be hard to find.
It's easy enough to where it doesn't take you a year to beat it, but not easy enough to beat it in 4 hours.
Three different levels of gameplay, and once you beat it on easy you are rewarded with "MUSIC PLAYER" and it plays all 28 track from the game, then after beating normal you can play any mission you want without having to save it on every level.
