The game is once again framed by the on-going battle between the Templars and Assassins, and players are actually assuming the role of Desmond, who lives in the present day and is able to experience the memories of his ancestor Ezio using a device called the animus. Like previous titles, there's also a modern-day component.
Brotherhood is a direct continuation of the events of Assassin's Creed II, only with the action shifting almost entirely to Rome.
