This complicated weapon essentially has four firing modes. When the fire button is tapped, it shoots a burst of rounds like an assault rifle. If the fire button is then held, it shoots multiple blasts like an automatic shotgun until released. When the secondary is held, a meter will raise in the reticle. If the secondary is released before the meter is maxed, it will fire a grenade. If the meter is maxed, it will fire a very fast rocket. It and the Slicer are the only two weapons that have "ammo," as shown by the three white rectangles at the top of the HUD. Firing the burst rifle or auto-shotgun will drain the ammo bars, while firing a grenade or rocket will deplete a full bar. The ammo slowly regenerates on its own.
