Tortuga & Tales from Tortuga Tortuga City is a community city building project in the world of DUAL UNIVERSE. The city is a place for trade, manufacturing and shady business. You'll never find a more wretched hive of scum, villainy and dashing rogues. Separated from the shackles of organization affiliations and political agendas, the cyberpunk world of Tortuga with its skyscrapers and neon signs will be home to adventurers and agents, artists and militarists, traders and thiefs.
