If you quickly jump off your sparrow and shoot it a few times, it takes off in the direction that your facing and explodes after about 50 feet. It will plow through enemies and if they are caught in the explosion at the end it can kill them. Its alot of fun aiming it over a ramp at some enemies and watching an angry sparrow tomahawk missile sailing towards them!!! Give it a try. If anyone scores a kill in crucible this was id love to see a video!
