Assassin’s Creed has always been known for its ability to let you sneak around to set up a more advantageous assassination position. This interview clearly demonstrates Francois Pelland’s (Assassin’s Creed Syndicate’s Senior Producer) ability to tiptoe around subjects like historical figures that will show up in Assassin’s Creed Syndicate :). While quiet on the subject Jack the Ripper, he confirms that Charles Dickens and Darwin will make an appearance in the game.
UPDATE (Sept 2015): Ubisoft has confirmed a Jack The Ripper add-on available with the season pass. Called it! Check out the trailer below
