ID Sniper Rifle

Origin
The ID Sniper rifle started as an art project devised by artist Jakob Boeskov. The original idea for the weapon was that it shot out GPS chips allowing police officers to tag persons of interest for later easy retrieval. According to its specs, "It will feel like a mosquito-bite lasting a fraction of a second. At the same time a digital camcorder with a zoom-lens fitted within the scope that will take a high-resolution picture of the target.  This picture will be stored on a memory card for later image-analysis." Due to so many people believing the hoax the rifle became exactly what it was designed to do.

Effects
Fires GPS chips to tag victims. The chip needs to be removed after forty eight hours or it will burst causing extreme pain.
