The gameplay in Tortuga will be open-ended, with the four playable nations and four different time periods making for a total of 16 different scenarios. Players will start the game with a small reserve of money and only a single basic ship, but, as they progress by completing missions or raiding other ships, they'll be able to acquire more powerful vessels capable of conquering the 60 towns and cities that feature in the game. Around 14 different types of ships will be available to players, and sea battles in the game will be fought using a real-time 3D engine.
