Naval Action - Travel Balloon is a consumable non-refundable DLC.
A truly revolutionary idea of two talented inventors and brothers, Joseph-Michel and Jacques-Étienne Montgolfier. The first flying vessel made of a globe of taffeta filled with air and an attached basket carried first passengers and landed in safety on the 27th of August in Paris, France. Several experiments of the like nature have been made since. It allows you to travel around the world using air currents.
It is a non-refundable DLC that allows you to receive the travel balloon every 24 hours. Once used you can keep one forever (if you dont delete or sell it)
