I was looking for a pistol type Zapper attachment for my Wii for other games when I saw this pack at Walmart. I thought it sounded pretty cool, so I picked it up. So far, I have no regrets.
The controller, or more specifically the Switch Shot EX-3, is a rather nice toy all around. The Nerf dart launcher portion fires a single dart at a time with a manual reload. It has decent range and accuracy and I'm generally pleased with it. The barrel can be removed and replaced with a Wii Remote, allowing for use with any game that can use the Wii Zapper peripheral. The back of the gun is exposed with plenty of room for a Nunchuck attachment. The downside is that the gun is a bit front heavy with a Wii remote attached, so long play periods might put a good deal of stress on the forearms. Granted, this can be alleviated by taking frequent breaks, which you should be doing anyway. Durability is an issue, though. I haven't broken mine, but the clasp at the front of the gun feels a little on the weak side. If you pull on the front housing too hard, you would likely break it and render the toy completely useless. Parents, help kids switch the Wii remote and Nerf dart barrel. There's an easy release spring button on the front of the gun, and should release with no resistance.
The game was unexpectedly good. The goal is to shoot targets and Nerf equipped Robots using various virtual Nerf weapons. There are several modes of play, and the game can be quite challenging. I would heed the e10+ rating on this game simply because very young children might not have the motor skills to enjoy the game. The game is fairly fast paced with most of the challenges being timed. There is also something to be said for accuracy. The virtual Nerf weapons react similarly to their real life counterparts, having a parabolic trajectory. This can cause some unusual aiming problems but shouldn't prevent the game from not being enjoyable.
Overall, my only complaint is the sometimes heavily cliched story and the balance point on the gun being too far forward. It is an excellent peripheral and I will highly recommend it to my customers.
