Zeus is a drone that can serve as a ship's 10th drone and was released on November 3rd, 2011. It is identical to the Apis drone in details, except in color and that you can only collect blueprints for this drone from the Golden Pirate Booty, which is available only on certain times. It has two slots just as the Apis but is also more expensive if you plan to purchase it instantly with uridium, at 1.5 million. With every blueprint collected, uridium price lowers in building cost. It is possible to obtain a completed drone from Booty Boxes with a very low chance.
