This was possibly the most beautiful PS2 game at the Square Enix booth. The full motion videos were stupendous, and the main game play was on par with Final Fantasy XII.
The game was fun, but the biggest issue was the control. It was possible to invert both the camera and aiming, but it was still a bit awkward to use. I have been told that the game is quite natural with keyboard and mouse play.
Another interesting feature is that experience can be allocated in one of two ways. You can put it into leveling up your character, or you can level up your guns. If you want a challenge, you can only focus on one aspect or the other, but it's probably best to use a split of the two.
