Field Drone

Field Drones, often referred to as Droppers, are hover drones developed by the Union Aerospace Corporation to receive and deliver parts to off-duty employees, engineers, and soldiers.

There are twelve Field Drones located throughout the campaign of Doom. Finding one will allow the player to acquire a new weapon modification, though only if the weapon itself has been acquired.
