Which company developed the first Assassin's Creed video game?

Ubisoft Montreal developed the first Assassin's Creed video game. The Canadian studio created the title for Ubisoft, establishing the gameplay and storytelling formula that would define the franchise.

Ubisoft Montreal had already worked on major action-adventure projects, including Prince of Persia: The Sands of Time and its related games. Assassin's Creed grew from ideas connected to that series, particularly the concept of a hidden order and an agile protagonist moving through historical environments.

The studio's first game introduced the cities of the Holy Land, including Jerusalem, Acre, and Damascus, as explorable settings. It also established the distinctive combination of climbing, rooftop movement, assassination contracts, investigation missions, and historical figures.

Other Ubisoft studios later led major entries. Ubisoft Quebec developed Assassin's Creed Odyssey, while Ubisoft Sofia worked on Assassin's Creed Rogue. Those later developers are common mix-ups, but Ubisoft Montreal is credited with creating the original game.
