|XShot Thundershot. jack of all trades....|
"Nerf + Water gun? Awesome, right? Well, it might be awesome looking - but it jams horribly and has terrible water flow! Only $30 but definitely one to avoid I'm afraid and not for the kids. There's a pistol too - single shot."
You do have to hand it to rival toy manufacturers attempting to bring out new and innovative gear, but i've never been one to mix my water and foam together. Different blasters for different purposes in my opinion. Still, they look pretty sweet, and no doubt someone like Nerf Mods + Reviews will be able to turn them into an absolute mega cannon of a blaster:)
You can see more on them at Foam from Above: they're featured at the TIA Toyfair 2011.
