Assassin's Creed is an action-packed game developed by Ubisoft Montreal. The game takes place in 1191 and centers around bartender Desmond Miles, who is kidnapped by Abstergo Industries. The corporation uses a machine called Animus to find an artifact that Desmond's ancestor, the assassin Altair, discovered. The player must explore a simplified model of the Holy Land, divided into seven main sections, to uncover the location of the treasure.

The game belongs to the category of open-world projects, which allows players to explore the world freely. The player must climb various buildings and towers to complete tasks, which are designed with Altair's jumping skills in mind. Investigation is a crucial part of the game, and merging with the crowd is essential to blend in with the environment. Altair must find the office of assassins in each city to get information about his targets and complete his missions.
