Using a machine that allows reading memories of people’s ancestors, Abstergo agents are trying to reach the long-gone pirate Edward Kenway, as they believe he possesses the knowledge needed to turn the tide of the endless struggle between Assassins and Templars to their favor. The game’s plot consists of two parts, one of which takes place in the year 2013 in Abstergo Entertainment lab, and the other in the early 18th-century Caribbean.

The game is a sixth installment of the Assassin’s Creed franchise, and the second that takes place in the colonial era. The player plays an Abstergo Entertainment agent which helps his superiors in reading the past by reaching memories of the long-gone pirate, Edward James Kenway, through one of his descendant's genetic samples.
