The Making of Assassin’s Creed: 15th Anniversary Edition examines the last 15 years of Ubisoft’s action series. The $50 standard hardcover edition features 240 pages of art from the series’ many games, as well as interviews with developers and articles covering Assassin’s Creed’s history.

The $100 Deluxe edition, shown above, includes the book with a special cover, a slipcover, and two lithograph prints. You can preorder both at Amazon.

Neither of the editions are discounted at this time, but Amazon often marks down books prior to release. If you order now, you’ll get the lowest price offered up until release thanks to Amazon’s preorder price guarantee.

By the time this book releases, it’ll be closer to 16 years since the Assassin’s Creed launched. Ubisoft actually announced this book last year right around the 15-year mark.

The World of Assassin’s Creed Valhalla: Journey to the North — Logs and Files of a Hidden One is a 176-page art book focusing on the most recently released game in the series, Assassin’s Creed Valhalla. The book is full of concept art and promotional illustrations, plus deep dives on the Viking lore and culture that inspired the game.

The standard hardcover edition is $50, while the Deluxe edition is $100 and includes an exclusive variant cover, protective slipcover, and two lithograph prints. There is also a digital Kindle version of the book available for $30. You can preorder each version at Amazon.
