Just like Politico Corrupto, Pirates are earned via their own business; in this case, the Piracy Operations Business.
After completing Bangkok’s “Secure a Pirate Vessel” job, you’ll unlock the Piracy Operations business and will begin earning Pirates at a rate of one earned every three hours, until you reach the business’s starter capacity of five Pirates.
After you’ve amassed a sizeable collection of your sea-fairing friends, you can put them to work in Episode 3 in the “Steal Japanese Auto Shipping Containers” job.
Head over to the Mafia Wars Facebook page to start earning these Pirates for yourself.
