From publisher blurb:
The Great War has left the world changed. The destruction of the old world has created opportunity for those skilled and brave enough to exploit it. In the skies over the Mediterranean, a new and daring breed of pirate flying the latest aircraft is taking advantage of the political instability between the old nations of Europe and those born out of the collapse of the empires of Austria-Hungary, Russia, and the Ottomans.
Join the Foreign Volunteer Force -- the Sky Rats -- and fight this aerial menace, or put together your own crew to plunder the unsuspecting!
Sky Pirates of the Mediterranean includes an alternate history of the world of the Roaring 20s, details of a dozen pirate factions operating through the Mediterranean and their aircraft, and new rules for Dogfighting for the Ubiquity role playing system.
