I haven't got the zapper yet, ordered ghost squad and the zapper for $50 in amazon.com (about a month ago pre-order) for the trigger button to fire gun, is it the B button or Z? Or is it depends on the game you play, like ghost squad and MOH heroes 2? The B one is just like a handgun, the Z one would be really like a submachine gun. I saw the demo from ghost squad, it uses Z button I think? By the way, I am happy that finally the MOH has online play function, not just a story arcade mode which you would sell it out after you are done with the whole story. For online play capable game, I don't mind to pay $10 more.
