Its a mouse with a gun handle, to put it simply.

Now this is rather intriguing, but can you imagine the learning curve involved?
Using a mouse is great, but there's nothing like the tactile experience of squeezing a trigger while playing an FPS,
which is what made Goldeneye so great with that N64 controller. Microsoft, I'm certain, recognised this and addresed
it with the design of the 360 controller.
I can barely keep up with the online competition as is. I'm just not ready to make such a drastic peripheral transition.
Zalman may have a bit of a hard sell with this one.
