Assassin's Creed began in 2007 and follows conflicts between the Assassins and the Templars across different historical periods. The Assassins defend freedom, while the Templars seek control and order. A science-fiction device called the Animus connects the historical stories by allowing modern characters to experience genetic memories from people who lived in the past.
Most entries combine open-world exploration with stealth, parkour, close combat, ranged weapons, missions, and optional activities. Earlier games emphasize climbing, rooftop movement, investigations, and planned assassinations. Later entries add larger maps, dialogue choices, equipment, skill trees, naval travel, settlement building, and more role-playing systems. The balance changes between releases, so one game may be a focused stealth adventure while another works as a broad action RPG.
The main character and setting also change. Altaïr works during the Third Crusade. Ezio Auditore's story moves through Renaissance Italy. Edward Kenway becomes involved in piracy and naval conflict in the Caribbean. Other games visit the American and French Revolutions, Victorian London, ancient Egypt and Greece, Viking settlements, feudal Japan, and additional periods. Assassin's Creed Black Flag Resynced returns to Edward's Caribbean story with rebuilt visuals and updated gameplay.
Ubisoft uses real cities, people, architecture, and conflicts as the setting for fictional stories; the games are not literal historical accounts. The franchise has also expanded beyond its main games into books, comics, a feature film, podcasts, exhibitions, live performances, and announced television projects. Each adaptation uses the same broader conflict while introducing its own characters, locations, and time period.
