Parents should be a little concerned—it’s a shooting and swordfighting game that offers nothing but heaping helpings of violence without any of the blood or gore that tips children off to the sickening horror of real-life violence. On the bright side, it's one of the few first person shooters that allows players to complete the game without killing anyone.
FPS fans owe it to themselves to check this game out, so they can see just what an improvement the Wii is over all other FPS control schemes.
Deaf and Hard of Hearing gamers will be find the game a little more difficult, as they’ll be missing many key audio cues, like when they're being shot at, as well as much of the game's story.
