While it seems to be addressed here already, i may as well mention it anyway. The default controls are not for everyone. I personally have no problem with it and quite like it because of the precision you get. Those who use the stylus with their left hand will have a hard time with it, but you can change the controls to use the face buttons for aiming if that is preferred, or the Circle Pad Pro extension. Now with that out of the way, this game is a great addition to the 3DS library. it sports a good length single player mode, fun online multiplayer modes, and heaps of achievements and challenge to keep you coming back. The difficulty of the single player levels can be tweaked to an insane level of precision, from 1.0 to 10.0, and let me tell you, 10.0 is definitely something you don't wanna take lightly since it is actually quite difficult. There is a lot of weapons, which can be combined and sold at your will in order to obtain stronger weapons. The dialogue was, in my opinion, fun and enjoyable, but i believe that it is not for everyone, and some could end up being annoyed by their constant chatter. Overall, if you find a control method that works for you, this is a great game that can offer you a lot, whether it be a meaty single player experience, or an interesting multiplayer mode.
