Not the ideal FPS.
Also, the voice-acting is not too interesting, so I always tune-out on the story. The graphics are not bad, it's on par compared to rather good-looking PSP games.
As for gameplay, the controls are not as bad as what most people say. If you choose the Type C or C' controls, then it should be much easier to control your character. However, since I'm new to FPS, I still found it hard to control. The lock-on feature on some weapons help a bit though.
I recommend this game to those who are addicted to the Ghost in the Shell anime series. However, for the rest of you, I can recommend 3 other games for you to play instead.
