Assassin’s Creed Syndicate may not have been released yet but considering the title is set in Victorian London there is no way that Ubisoft could resist announcing some DLC early for the game by focusing entirely on one of England’s greatest unsolved mysteries.
Ubisoft has announced at Sony’s Tokyo Game Show that some DLC will add content to the game that relates to Jack the Ripper will be released sometime after the game is released. Currently no details for what this Jack the Ripper DLC will contain were revealed, but it does state that it will be included in Assassin’s Creed Syndicate’s season pass.
