Xur should sell an exclusive weapon for halloween and christmas Halloween weapon - the phantom. A hand cannon with three barrels that fire three bullets per shot. There are 27 bullets so that gives nine shots. The perk is that two bullets per shot over penetrate targets and pass through them. Winter - chilled pain. Another hand cannon that fires icicles (arc) and the perk is that two bullets in the magazine can freeze targets for 2.5 seconds.
