Great highly addictive game, hard to put down once you've got the hang of it.
The graphics are not "next-gen" in that they are on par with Kameo or PGR3 of course, but they use what power is available and most of all required to make an arcade shooter shine in a wonderful way. A psychedelic experience greatly enhanced by the frantic music constantly pumping you up for more nerve-twitching action.
If I were to mention a gripe it would be that the 89 levels are not really laid out in order of increasing difficulty. There's some levels in the 50's that are easily beat on black belt while there's also one in the 20's that is much much harder on a lower difficulty. Since each level only lasts a minute this does not matter too much, as overall it's just one hell of a shooting experience that you'll keep coming back to again and again and again and again whenever you have 30 minutes to kill.
