Weapon

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 along with grenades, melees, and some super 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; any type of gun can be used by all Guardian classes.

For a list of all weapons, view the category page.

Weapon Types
Each weapon fits into one of three inventory slots according to its type: primary, special, and heavy. A player can equip one weapon of each type and hold up to nine more of each type in the inventory. Players can equip any weapon in their inventory at any time, but changing the equipped Special or Heavy weapon will forfeit half the weapon's ammo in PvE and all of the weapon's ammo in PvP.

Primary Weapons
Primary weapons are the main weapons used by Guardians. There are four different types of primary weapons:
 * Scout Rifles: Semi-automatic rifles with high accuracy.
 * Pulse Rifles: Burst-fire rifles with high recoil between shots.
 * Auto Rifles: Fully-automatic rifles with medium accuracy.
 * Hand Cannons: Revolver-like pistols with medium range and high impact.

Primary weapon ammo can be replenished by picking up small, white boxes.

Special Weapons
Special weapons deal higher amounts of damage, but ammo for them is harder to find and they are less "all-purpose" and useful only in specific circumstances. There are four types of special weapons:
 * Shotguns: Close-quarters, but high damage.
 * Sidearms: Pistols with a high fire rate, but low range and impact.
 * Sniper Rifles: Long-range scope and high damage.
 * Fusion Rifles: Close- to mid-range directed-energy rifles that have charge cycles.

Special weapon ammo can be replenished by picking up small, green boxes or by opening green ammo crates.

Heavy Weapons
Heavy weapons deal massive amounts of damage. There are three types of heavy weapons: Heavy weapon ammo can be replenished by picking up large, purple boxes or opening purple ammo crates.
 * Machine Guns: High rate of fire and extreme magazine capacity, deals a high amount of damage.
 * Rocket Launchers: Deals massive damage to a large radius.
 * Swords: Deals massive damage to a single target and can also be used to block damage.

Relics
Relics can only be used during special activities and cannot be stored in the inventory.
 * Aegis: An artifact with various uses and abilities. Available only in the Vault of Glass raid.
 * Cleaver: A Hive sword. Can be found in The Sword of Crota, Fist of Crota, and Crota's End.
 * Scorch Cannon: A shoulder-mounted Fallen weapon resembling a rocket launcher. Available in A Kell Rising, Wolves' Gambit, and the Prison of Elders.
 * Tomb Husk: A Hive item used to activate devices. Usable in Lost to Light, Summoner's Circle, Last Rites, and King's Fall.

Enemy Weapons
Enemy weapons are only used by the Fallen, Hive, Vex, and Cabal. For a list of enemy weapons, see the category page.

Attack Power
A weapon's Attack Power is represented by a number. The higher a weapon's Attack Power is, the more damage it will do to enemies. All Year 2 legendary and exotic weapons can be infused to a maximum Attack of 335.

In regular Crucible modes, weapons' Attack Powers are normalized. However, Attack Power is a factor in Iron Banner and Trials of Osiris.

Attributes
Weapons are differentiated from each other by several attributes. Some of these attributes are shown in-game, while others are hidden and only accessible through the Destiny API. Most attributes are rated in a 1-100 scale.
 * Rate of Fire: How quickly shots can be fired in succession.
 * Impact: The damage inflicted by each round.
 * Range: The effective range of the weapon. Affects both damage dropoff and the range at which aim assistance benefits are active.
 * Stability: How much the weapon recoils.
 * Recoil: The direction the weapon recoils when fired. Lower values kick more sideways, and higher values kick more upwards. This attribute is hidden in-game.
 * Reload: The time it takes to reload the weapon.
 * Magazine: The number of shots that can be fired before reloading.
 * Charge Rate: How quickly the weapon charges. (Fusion Rifles only)
 * Blast Radius: The explosion radius of the projectile. (Rocket Launchers only)
 * Velocity: The speed of projectiles fired by this weapon. (Rocket Launchers only)
 * Energy: The amount of "Ammo" a sword can hold at full capacity.

In the Crucible, although weapons' Attack Powers are normalized, their attributes are not.

Rarity
Generally, the higher a weapon's rarity is, the higher its damage rating will be. Weapon rarities can also affect the number of available upgrades for that weapon.

Though players may carry as many exotic weapons as they like in their inventory, only one exotic weapon may be equipped at one time.

Perks
All non-basic weapons can be upgraded with perks by earning experience with the weapon equipped. Perks may be different optics options, increased damage, or adjusted attributes. Some perks must be purchased with Glimmer, Weapon Parts, or other materials.

All Guardians on the same account will receive experience faster for a given weapon type when any Guardian on that account has achieved 5,000 (primary), 2500 (special), or 1,000 (heavy) kills with that weapon type.

Damage Types
There are four different damage types that a weapon can have: kinetic, arc, solar, or void. Damage types can inflict additional damage to an enemy's shields. The color of an enemy's shield represents which damage type it is vulnerable to. Any unique damage types that are not used against their respective shields will only inflict the default damage of the weapon.

A damage type will do additional damage to all enemies if the corresponding Burn modifier is active.
