I've never seen this before and I can't find much info about it. the best info I could find was from some amazon reviews.
At first I thought it would be handy to be able to rebarrel the missle launcher on the top for micros, but according to this their just stomp rockets
Not to sound completely like an idiot, but when I ordered it, I thought that he would be able to shoot the missiles from the gun as well. Not so. The missiles are a part of a stomp rocket which you remove from the gun and just stomp them 20 feet into the air.
I almost lost interest in this blaster completely but then one of the comments suggested that the blaster uses mega darts
The darts are quite large too - not like the Nerf ones which are small and flimsy, eventually bending from use. These are fatter, thicker, and longer
This would suggests good mod potential, if anyone wants one there are some ebay listings in the UK for as low a 10 euros without shipping.
