Good if you love the arcade version; better fps out there
I bought Ghost Squad having wasted many hours in arcades when I was younger. It was a real buzz playing at first and still is, but don't expect too much. There are only a few missions and not much changes no matter how well you do. The Nyko Perfect Shot guns work well with this game because you only need the nunchuk occasionally. Multiplayer is fun (though for some reason no split screen) and probably offers the best of this game.
