Assassin's Creed is an action-adventure-stealth video game developed by Ubisoft.
The game centers primarily around the rivalry between two ancient secret societies: the Assassins and the Knights Templar, and their indirect relation to an ancient species pre-dating humanity, whose society, along with much of Earth's biosphere, was destroyed by a massive solar storm.
A machine known as the "Animus" allows its user to view the genetic memories of his or her ancestors.
Within the Animus, the player explores the memories of a number of Assassins if dufferent centuries.
