Years passed, but the brilliant mind of the Master did not dim, did not lose the fatal force and accuracy of his blow. Ezio Auditore embarks on an epic journey to find Altair's missing library, and at the same time, perhaps, the key to victory over the Templars, the sworn enemies of the brotherhood of Assassins. The path leads to the troubled Constantinople, where the growing army of the Knights of the Order of the Temple threatens the Ottoman Empire. Following in the footsteps of his great predecessor Altair, Ezio must crush the Templars for the last time. The stakes are constantly rising, and what began as a pilgrimage has turned into a race against time.
