In reference to the powerful electrical bolts discharged when it is fired, this weapon is appropriately named Tempest, meaning "storm." The Tempest heavy assault rifle is another of the weapons used during the final months of the nation's military war against the demons. The Tempest uses a combination of a powerful magnetic field generator and high-voltage electricity to discharge a burst of electrical "balls". Designed to damage as many enemy combatants as possible, the firing pattern is a spread of independently moving projectiles that move in a random, forward path.
