Assassin's Creed Valhalla is a 2020 action role-playing video game developed by Ubisoft Montreal and published by Ubisoft. It is the twelfth major installment in the Assassin's Creed series, and the successor to 2018's Assassin's Creed Odyssey. Principally set in the years 872–878 AD, the game recounts a fictional story during the Viking expansions into the British Isles. Players control Eivor Varinsdottir, a Viking raider who, while attempting to establish a new Viking clan in England, becomes embroiled in the centuries-old conflict between the Assassin Brotherhood, who fight for peace and liberty, and the Templar Order, who desire peace through control. The game also includes a framing story, set in the 21st century, which follows Layla Hassan, an Assassin who relives Eivor's memories so as to find a way to save the Earth from destruction.
