The game takes place during the Third Crusade. The gamer plays as a member of the assassin sect Hashashin known as Altaïr (of Greek and Arabic origin, roughly translates to ("The Flyer") or ("The Eagle"). The player will be able to travel through three cities, Jerusalem, Acre, and Damascus. The cities are populated by many people and the way the player controls Altair affects how people around you react to his or her presence. For example, when going through a crowd, if you lightly move someone out of the way, it wont make too much of a difference, however, if one throws someone to the ground and kills him, the crowd may unite against the player and he or she will then have to find a way out. Similarly, for example, if you shove a person aside, he/she may shove you back. If you climb walls, civilians will gather around, attracting unwanted attention from guards . (source: Wikipedia)
