One of the best games on the PSP, good replay value, but suffers from some minor problems.
the only problem i have with this game, is that the background can be kinda dark, so if you're playing the PSP in a bright place its kinda hard to see given that this is a portable game you'll be out on the road playing it. But if you're playing it in the comfort of your own home its fine.
Here's how the game goes, you start off as a young man on his initiation to join the Warriors, so you begin the tutorial to learn the controls which are really easy to learn, after you beat up a few bums, you'll be thrown into the main story. where you go past the events that lead to the big gang meeting where Cyrus some big shot is assasinated and the Warriors get blamed for it.
every mission is different and has some great lines and stays true to the movie it was inspired from.
get this game if you haven't already, its really value for money.
