A must-have for fans new to the game world as well as those who have been fascinated with the series since day one.This encyclopedia features new information and amazing artwork, updated content from the upcoming monster Assassin’s Creed III game and upcoming graphic novel Assassin’s Creed: The Chain.

Artists like Craig Mullins, Tavis Coburn, 123Klan, Gabz, James NG, David Alvarez and many others were given free reign to draw an Assassin from the period and style of their choice, of which the artworks were included in the Encyclopedia. There was also a "cartes blanches" section that featured artwork by other professional artists and fans of the series.

A Black Edition was released with the Animus Edition of Assassin's Creed: Revelations.

A White Edition was released through UbiWorkshop and with the Ultimate Edition of Assassin's Creed: Revelations.
