Ubisoft already has not one but two Assassin’s Creed games planned for release, with Assassin’s Creed Unity for the PlayStation 4, Xbox One, and Windows PC, and Assassin’s Creed Rogue for the PlayStation 3 and Xbox 360. So, Ubisoft’s announcement of a season pass for Unity–a bundle of downloadable content available for purchase that will be released following the game’s launch–was no surprise.

The inclusion of an all new Assassin’s Creed spinoff game as part of that season pass, however, was an unexpected addition.

Titled Assassin’s Creed Chronicles: China, the new game comes from Climax Studios and is, rather than its open-world brethren, a 2D sidescroller more in the vein of Super Mario Bros. or Rayman Legends. Set in 16th century China, players control Shao Jun, who has ties to Assassin’s Creed II protagonist Ezio Auditore. The game will feature the franchise’s signature parkour and fighting, albeit all on a 2D plane.

Chronicles is not the first two-dimensional Assassin’s title, as the Nintendo DS game Assassin’s Creed II: Discovery was also set in 2D.

Also included in the season pass is a new story campaign, Dead Kings,” which is set after the events of Unity, as well as a number of new missions, weapons, and customization options for the game’s protagonist, Arno.

No release date is set for the season pass, which will cost $29.99. Ubisoft promises all the additional content will be available by some time in early 2015, while Unity itself will be released Nov. 11.
