While all weapons have kinetic (for firearms) or explosive (for rocket launchers) damage, some may deal additional elemental damage. Arc: A type of electric energy that causes a wide area-of-effect damage. Solar: Incendiary damage that can ignite enemies. Void: Gravitational damage caused by a close-range, heavy gravity field. Weapons are equipment designed to inflict damage on living beings, vehicles, or structures as an effect of combat. Weapons play a dominant role in the Destiny series, as along with grenades, melees, and somesuper abilities, weapons act as the primary mode of combat and defense against hostile forces in the game. Multiple types of weapons exist, some of which may be more effectively used by certain classes and subclasses, or while wearing certain pieces of armor. There are, however, no restrictions on which classes can use which weapons; every type of gun can be used by every Guardian class.
