Due to poor whether conditions that have blighted the start of 2015, such as frost and snow the heavy ammo crop has failed. Xur used to source his heavy ammo synths directly from the heavy ammo farmers of the jellyhorn province. But since the crop failure he is unable to provide this service to his stange coin gathering masses. The gunsmith however has just bought a new ferrari class ship with all the glimmer he has been making from his heavy ammo garden patch in the tower greenhouse. All guardian are advised to pick up greenhouse for just 25001 glimmer from their local tower merchant amd grow their own for the time being. Alternatively the heavy ammo glithch was manufactured by a corporation known as "Bungie" and they have been hoarding xurs supply of synths purely for giggles and creating anarchy among the hardworking masses.
