The English campaign is based loosely in part on Rafael Sabatini's Captain Blood novel's first twelve chapters, as the main campaign character name, description, the events he is involved in and the characters resemble with the ones described in Sabatini's novel.
The player then embarks on several quests, of which some are mandatory. At the start, the player may begin alone, or choose one of four navies: England, Spain, France and the Netherlands.
The game is a role playing game, and the plot is rather open ended.
