I got it for Christmas and was very intrigued. At the core you have a basic first person shooter, with a little bit of puzzle solving. But the thing I liked a lot about it was the intense graphics. Gameplay is smooth and intense. You have to aim right at the guy to hit him.
Joysticks are a good asset.
The Graphics are the best I have seen for a while. The guys mouth moves almost at the right time. Ping ping pow pow. Those sounds are not uttered in this game. The sounds are all lif-like.
