Japanese gangster beat 'em' up storyline.
The storyline is very in depth and also has some twists and turns which would keep you guessing how things are actually going to end. It is not to say very long in length but the game progressively makes you take steps and also some of the side quests do have some relation to the story so do make sure you do them to get the full understanding, not to mention they help beef up your character.
Graphic wise the game is impressive. Smooth charater animation as best as possible. You are able to punch, kick and also use objects to bash, trash and KO your opponents. Not to mention using your MAX abilities for drastic effects like smashing people into the vending maching or tables. Also some weapons have the ability to be used as a MAX finishing move.
Sound in the game is not too bad. has some atmospheric effects like walking in the streets you can hear cars or people talking around you. The fighting of course is all the hits and crashing effects. The ending song is pretty cool too.
The gameplay is relatively simple will not tale too long to learn definately due its mostly button mashing and all that, but there are some combos to learn which also make it interesting pulling some of those moves.
Overall a good game worth playing actually for the story but getting to the end is the part that you'll have to work for. Enjoy =)
