The controls are a bit weird, but I got used to them pretty fast. Great storyline with funny humor. Good graphics and really fun combat. My favorite thing about this game is all of the weapons. The weapons are the thing that is really in depth in this game. 9 weapon types, stats for the weapons, can merge weapons, and a whole lot more. The multiplayer is really fun too. My favorite game so far on the 3ds.
I enjoyed the story line and the fact that in the game-play you have several other mini missions that you can do to get achievements. The reason it get the rating that it does; however, is that because of the design of the controls and how they effect the game. The way that the screen touch screen controls the aim and you still use the stick to move makes it really hard to hold the system in a way that the 3d works well. In addition after about a half hour of game play my wrist was left cramped and my fingers tingly. The worst part was that the touch screen control system was the best control option that was given.
Overall, I would say this game was not a complete waste of time, but I would not suggest it.
