Ubisoft claims 9 of its PS4 games won’t work on PS5, outside of Sony’s 10-game exclusion list

Ubisoft has claimed that a number of its current-gen games are not backward compatible on PlayStation 5, bringing into question recent Sony statements regarding PS4 software support on its next-gen console.

According to Ubisoft, nine of its current-gen releases will not be backward compatible on PS5.

They are Assassin’s Creed Syndicate, Assassin’s Creed Chronicles Trilogy Pack, Assassin’s Creed Chronicles India, Assassin’s Creed Chronicles China, Assassin’s Creed Chronicles Russia, Risk, Star Trek Bridge Crew, Werewolves Within, and Space Junkies.

UPDATE: Ubisoft said it has removed the Connect article because there “may be inaccuracies” regarding PS5 backwards compatible games.

ORIGINAL CONTINUES: Earlier this month Sony released a list of PS4 games not playable on PS5, which included just 10 titles, none of which are Ubisoft games. At the time, Sony said the list was subject to change and excluded demos, media, and non-game applications.

The listed games were DWVR, Afro Samurai 2 Revenge of Kuma Volume One, TT Isle of Man – Ride on the Edge 2, Just Deal With It!, Shadow Complex Remastered, Robinson: The Journey, We Sing, Hitman Go: Definitive Edition, Shadwen, and Joe’s Diner.

While Sony claimed that “the overwhelming majority of the 4,000+ PS4 games are playable on PS5 consoles,” it also noted that “some functionalities that were available on the PS4 console may not be available on PS5 consoles” and “some PS4 games may exhibit errors or unexpected behavior” when played on the next-gen system.

It advised users to test games on PS5 before purchasing any add-on content, in case of undesirable results.

It’s currently unclear whether the Ubisoft games listed above run on PS5 with sub-par performance or are not playable on the console, but we’re checking with the publisher.

Ubisoft said that on Xbox Series X/S, all its Xbox One games are backward compatible.

Microsoft said this week that all Xbox, Xbox 360 and Xbox One games playable on Xbox One today—excluding those that require Kinect—will be available on its next-gen consoles when they launch on November 10.

Sony recently explained how game transfers and game saves work between PS4 and PS5. Transferring PS4 saves to the PS5 version of the same game is down to individual developers, meaning the ability to do so will vary title by title.

Select PS4 games will benefit from the PS5 console’s Game Boost, which may make PS4 games run with a higher or smoother frame rate. Ghost of Tsushima will utilise PS5 Game Boost to support frame rates up to 60fps.
