Assassin’s Creed is an Action-adventure game set in an open-world environment and played from a third-person perspective, in which the player primarily assumes the role of Altair as experienced by the protagonist Desmond Miles. The main objective of the game is to lead the Assassins. To achieve this goal, the player must travel from the Brotherhood headquarters in Sayyaf across the Holy Land, known as the Kingdom, to one of the three cities, Jerusalem, Acre, or Damascus, to locate the Blood Agent in that city.
The Agent is given a safe house there, providing the player with minimal information about the target and requiring them to perform additional reconnaissance missions before attempting the assassination. These missions include pickpocketing and completing tasks for the assassins and fellow assassins. Additionally, the player can participate in any of the land objectives.
Including climbing a tall tower to map the city and rescuing citizens who are being threatened or harassed by the city’s defenders. Various additional missions do not advance the plot, such as hunting and killing Templars and collecting the flag. After completing each kill, the player is returned to the Brotherhood and rewarded with a better weapon or graded before going after the next target or given another set of objectives. The player is free to choose the order of specific objectives.
