This LEGO game is different to the previous in that it is a single storyline, with 18 levels, and an open world HUB. To move from one level to the next, a character will often have to find or purchase a ship to sail between islands, and a carriage or horse to travel on larger pieces of land. When a minikit is completed (by finding 5 treasure chests in each level), that ship or vehicle is unlocked. The story follows on immediately from the previous, with the pirates having captured and occupied the Imperial Fort, and finding a large stash of treasure; with the rest of the Imperials struggling to cope, following the loss of their leader, Imperial Admiral Bricker. The game features a total of 60 characters and 40 official vehicles.
