Spinmetal is a material that is used to upgrade legendary and exotic weapons and armor. Spinmetal can be harvested from Spinmetal Leaves, which appear randomly in some areas on Earth. Spinmetal may also be awarded to players for opening loot chests on Earth, completing Daily Heroic Story Missions, turning in Patrol or Queen's Wrath bounties, or opening Judgment's Grant packages. They can be purchased from the Vanguard Quartermaster for Legendary Marks at a rate of 10 Marks for 20 Spinmetal.
Once obtained, Spinmetal is stored in a player's inventory. 200 Spinmetal can be stored in a single stack, after which point a new stack is started.
Spinmetal is light but strong and used in everything from personal armor to jumpship structural components. Spinmetal rounds are lighter and more compact than normal rounds, allowing for a larger ammo reserve to be carried by players.
