Abstergo Industries with an employee, Lucy Stillman, after being forced
to relive the genetic memories of ancestral assassin Altaïr Ibn-La'Ahad
through a machine known as the "Animus". After escaping from Abstergo,
Desmond enters a device which is more advanced than the original Animus,
the Animus 2.0, and relives the genetic memories of ancestral nobleman
Ezio Auditore da Firenze, who lived during the Renaissance period of the
late 15th and early 16th centuries in Italy. The player controls Ezio,
who becomes an Assassin after his father and brothers are murdered by a
traitor to their family. While controlling Ezio, the player can explore
game renditions of Italian cities, regions, and landmarks in open world
gameplay.
