Dead Kings takes place after the events of the main game, and places Arno in a position where he wishes to get out of France as soon as possible, but along the way an old ally crosses his path and Arno reluctantly goes searching for an ancient artefact, which is located below the streets of Franciade. As Arno goes out seeking answers he finds that a familiar face has turned to the other side, and he must get to the artefact before it’s put in the wrong hands.
Before the initial release Ubisoft had proposed that Dead Kings would be one of the darker stories in the Assassin’s Creed universe, but after the initial introduction to the story Unity takes a turn for a more lighthearted approach, that is situated in dark locations rather than actually dark in tone. This isn’t necessarily a negative point, but the plot itself isn’t anything that will make you replay its contents. The story is rather forgettable and rushed, with many dynamics left either unexplained or undeveloped, lacking a decent narrative flow that leaves the story hanging on a thread as the campaign goes along.
