Which studio developed Assassin's Creed Origins?

Ubisoft Montreal developed Assassin's Creed Origins.

The Montreal studio created Origins as a major reinvention of the series, adding role-playing systems, experience levels, loot, and a broader open world. The story follows Bayek of Siwa in Ptolemaic Egypt and explores the early formation of the Hidden Ones, the organization that later becomes associated with the Assassin Brotherhood.

Ubisoft Quebec developed Assassin's Creed Odyssey, while Ubisoft Singapore contributed to naval technology and other projects across the franchise. Ubisoft Sofia is associated with titles including Assassin's Creed Rogue and Assassin's Creed III: Liberation. Origins was released in 2017 after a year without a mainline Assassin's Creed game, giving the development team additional time for its redesign.
