Instead of being settlers the players are now pirates, with pirate warehouses located on islands in the waters around Catan. Pirate warehouses are equivalent to settlements in Catan, and the player receive resources from these warehouses whenever a die roll matches the number showing on that island. These resources take the form of equipment cards, and the resources are wood, wool, rum, sabers and gold. With these, players construct ships and more pirate warehouses or buy development cards. Instead of a robber, players must now beware of a Ghost Pirate, which can block the resources provided by a warehouse.
