While in battle pilots may get the chance to pick up salvage, which is dropped whenever a ship or drone is destroyed. Salvage glows green and can be collected by flying through it.
Win or lose, any salvage acquired in battle will be available to pilots once the battle is complete and they are back on the carrier. It is shared between all active team members at the end of a battle.
The three salvage types (Raw, Component and Prime - common to most rare respectively) are used by pilots to craft new ships when blueprints are unlocked (Ship Crafting).
