Assassin's creed revelations is the final chapter of Ezio Auditore life. It has an amazing storyline as Ezio tries to find out what has happened to the greatest assassin that ever lived, Altair. You have to collect 4 keys to unlock the chamber in Masyaf. As you collect those keys, a flashback occurs on what happened to Altair and the assassins guild. This storyline was one of my favourites as it connects the three franchise characters together (Altair, Ezio and Desmond). Overall it's a good game to wrap up Ezio's Adventures.
