Due to the ongoing laundry list of issues plaguing Assassin's Creed Unity, Ubisoft is trying to make right by their mistakes. To start with, they are pulling the Season Pass for Assassin's Creed Unity. If you already bought the Season Pass, you not only get the previously promised content but also a free game of your choice. If you did not buy the Season Pass, you will get the Dead King's DLC for free but no added free game.
