Also in phase 2 of the Sandstorm expansion (from their press release):

• CONSUMABLES: Players may now craft Consumable items that can be used once while in a combat mission to give a short-term boost. Once used, that item is consumed. In order to equip a consumable, you must have a Consumable in your inventory, and fill the Consumable slot on your Equip screen. Only one consumable may be equipped at a time.
• SALVAGE: Weapons and Armor that you do not desire to keep may be salvaged by clicking the Salvage button while the item is selected on your Inventory menu. When a weapon or armor piece is salvaged, you will receive a component loot drop put into your inventory (many of the components gained through salvage are useful when crafting consumables).
