The idea is that you can get on your ship in Havana and set sail to Kingston, stopping off at little islands, coves, plantations, forts, jungles and villages along the way – all of which you can explore after dropping anchor and swimming ashore. (Yes, swimming. Assassins can swim now. They can even swim underwater using pirate diving belts to explore shipwrecks.) Each of these locations types is likely to have their own purpose. Villages and coastal settlements will harbour sidequests and the chance to upgrade your ship with bigger cannonballs, while jungles hide Mayan ruins which will almost certainly be used for Ass Creed’s terrible Chariots-of-the-Gods-meets-Dan-Brown metaplot.
