To set up the game, you need the game components from the CATAN base game as well as new frame pieces and hexes from the expansion. This provides you with quite large a game board, allowing you to go on exciting journeys of exploration and discover new land.
The new Explorers & Pirates expansion is based on the CATAN base game rules but also contains a number of new game mechanisms. For example, ships are now equipped for expeditions and can be moved freely across the board. In the ships you transport settlers, crews, fish, or spices across the seas. Your goal is to build new outposts on the islands that are still undiscovered and to complete the Council of Catan's missions in the most skillful way possible.
