Assassin's Creed: Revelations is a 2011 action-adventure stealth video game developed and published by Ubisoft. It was released for Xbox 360 and PlayStation 3 in November 2011, and for Microsoft Windows in December 2011. It is the fourth major installment in the Assassin's Creed series, a direct sequel to 2010's Assassin's Creed: Brotherhood, and the final game in the 'Ezio trilogy'.
The story is set in a fictional history of real world events set in three time periods, and features three returning protagonists: Altaïr ibn-La'Ahad in 13th century Masyaf, Ezio Auditore da Firenze in 16th century Constantinople, and series protagonist Desmond Miles in 21st century America.[4][5] The main story follows the Assassin Ezio's journey to unlock the secret of Altaïr's vault in Masyaf using disc-like artifacts containing Altaïr's memories. Intersecting with these historical events are the modern day activities of Desmond, who relives Ezio's memories to find a way to fight against the Assassins' enemies, the Templars, and to prevent the 2012 apocalypse.
