Has potential, but lack of polish hurt this game. Buy if you're a FPS fan and you can find it for $20 bucks or less!
GAMEPLAY - The levels are long, yet very linear. I think this actually works well with the wii-mote, as the control scheme makes turning a bit slower then the typical FPS but the levels are designed so you don't have to be rapidly and frequently turning. Still it would have been fun if you could explore a little or go through levels in different ways. Some say there is a learning curve with the controls, but I picked them up right away. Aiming and shooting with Wiimote in general feels pretty good. The biggest problems with the controls are that the cursor seems a little buggy at times, and reportedly this can be fixed by turning off the wii-mote speaker. The enemies are generic and are not very smart. Personally, I liked the sword fights. I would've liked a bit more variance in the weapons, but I guess that would have been out of place in a game set in contemporary times (i.e. Japanese Mafia don't carry Gravity guns, and BFGs). GRAPHICS - Sometimes it was pretty good with decently detailed models and environments. However at other times it looks a bit bland. I'd have to say they were a inconsistent. Some of the lighting was impressive. Overall, I'd say the graphics are respectable and while I'm sure the Wii can do better, it still looks better then the average PS2 or Gamecube FPS, and at the very least are not ugly. VALUE - The single player is about average in length for a FPS. The game has local multi-player which is actually quite fun. Online multiplayer would have done wonders for it's replay-ability but is not included.
Overall, I'd like to say that while this game is technically not a great game, if you're a FPS fan and want something a little original, it might be worth checking out. Definitely look for it in the bargin bin though.
