Below is the game I want to know more about. I've heard it briefly described by several E3 attendees.
"After Star Fox I got some hands-on with a target shooting game. I was instructed to point the 3D camera on the 3DS at a little question mark block that was laid on the table. As I did targets started popping up and I actually had to physically walk around the table to shoot them. After destroying the targets, a giant dragon popped out of the question mark block. It kept trying to tear my virtual face off, but I could easily pull back away from the beast. I shot the weak points on the dragon and caused it to implode in a glorious fashion. This was one of the coolest uses of the technology I had ever seen, and it was ridiculously responsive in every move that I made with handheld."
