Assassins Creed presents an epic story set in the time of the Crusades and Richard Lionheart. Altair is the former leader of the Assassins, now discredited for having failed a crucial mission concerning the retrieval of Templar treasure. Sinan, leader of the Assassins, offers his predecessor an opportunity to yet again prove his worth to the Assassins. The mission he gives Altair is not a simple one. Altair must travel into the Holy Land and assassinate men who are said to be involved in exploiting the volatile situation brought about by the Third Crusade. This would eventually allow Sinan to expand his business into the region, after the feuding parties had been eliminated and the situation stabilized.
The game begins when Altair finds himself in a chaotic mess that is the Holy Land. While Richard Lionheart and Saladin, leader of the Saracen army, battle over the Holy Land, local governors have begun to take advantage of their positions of power. These exploitative, greedy men are the marks Altair must take care of in order to regain his position with the Assassins. Soon however, Altair begins to notice that the men are bound together by a secret society well known to the Assassins. The secrets of the society begin to unfold as Altair progresses.
The game will be out for Xbox 360 in early 2007.
