a not so good and yet not so bad game...
Graphics = the graphics is actually good for a ds game
Gameplay = the controls are a bit frustrating at first but if you have played some FPS on ds before, you should have no trouble at all. the major flaw about this game is the save system. if you die you start again at the beginning of the chapter. Sound = trust me, you must have a headphone to be able to enjoy the game great audio.
Replay = there's nothing to do at all other than to play it all over again. there's no unlockables, secret stuff of other hidden things.
