Assassin's Creed Altaïr's Chronicles

As the direct prequel of the critically acclaimed console title
Assassin’s Creed, discover more of the story of Altaïr as he must find
“the chalice,” an object of such power that whoever is in possession of
it can end the Crusades.

Altair will explore a fully realized 3D world traveling through four
cities of the Crusade’s Middle East. The game will feature acrobatic
moves and exhilarating combo attacks that mix both sword skills and
kicks.

The setting is 1190 AD. The Third Crusade is tearing the Holy Land
apart. You, Altaïr, intend to stop the hostilities by suppressing both
sides of the conflict.
