On March 19, 2014, images leaked for the next game, titled or code-named Unity, showing a new assassin in Paris. The screenshots show new "parkour up" and "parkour down" buttons, a new navigation mechanic as noted by Kotaku. Kotaku also stated that Unity would release in late 2014 on PlayStation 4 and Xbox One, and would be set during the French Revolution and feature an assassin named Arno. On March 21, Ubisoft confirmed the game's existence, having been in development for more than three years, by releasing pre-alpha game footage. They also confirmed the game's release date of Q4 2014, and that it would release on the PlayStation 4, Xbox One, and Windows.
