Give 'em the silent treatment
Edward Kenway is a pirate, but that doesn't mean that he needs to turn everything into an ostentatious affair. No, sometimes it's more efficient to move like a cat stalking its prey, waiting for the perfect opportunity to strike.
That's exactly what he does in this trailer -- he uses the environments to his advantage to methodically dispose of his targets. He may be decked out in pirate garb, but that assassin blood runs deep through his veins.
