A great game but ruined but its difficult controls.
The graphics and sound are very nice, but this game gives extremely painful hand cramps which ruins the overall gaming experience. Especially during wifi, when you have to fight tough opponents, hand cramps can get even worse. Holding the DS with only your left hand, and constantly pressing the L button to shoot while you are moving with your DS just bothers you too much that you don't even focus 50% on the game. I was heavily dissapointed as an FPS fan. I just believe that generally the mouse is the ultimate controller for the FPS. It is not the game's fault. It just seems that the DS is not right for a FPS game.
If you have a weak hand and if you dislike FPS this game is definately not for you. However if you can handle the pain and if you can find a way to control that is right for you, this game can be really great.
