Batman Arkham Sequel That Never Was: New Footage Reveals Cancelled Game Featuring Damian Wayne

A newly surfaced video has reignited interest in Project Sabbath — the long-rumoured but ultimately shelved sequel to Batman: Arkham Knight. Shared by YouTube channel The Atomsmith, the clip showcases a chase sequence between Batman and Killer Croc, using assets repurposed from Batman: Arkham Origins.

It's a brief but tantalising look at what might have been, had Warner Bros. Games Montreal gone forward with the project.

Damian Wayne Was Set To Don The Cape

Originally whispered about as early as 2016, Project Sabbath was intended to place Damian Wayne, Bruce Wayne’s son, at the heart of the story. Unlike the previous Arkham games, this sequel would’ve explored a grittier Gotham with an ageing Bruce Wayne stepping aside. Concept art that emerged back in 2019 hinted at a more rugged Bruce, a worn-down city, appearances by Gorilla Grodd, and even a version of the Nemesis System — made famous by Middle-earth: Shadow of Mordor — reportedly integrated into the gameplay.

Fresh artwork from Rodrigue Pralier, a character artist who worked with WB Games Montreal in 2014–2015, has now offered a closer look at several of these characters.

While the original ArtStation page featuring the designs has since been pulled down, fans have preserved the images online. These include redesigned looks for Damian Wayne, a bearded Bruce Wayne, and additional appearances by Killer Croc and The Huntress.

Gotham Knights Took Its Place — And Flopped

Despite its ambitious scope, Project Sabbath was eventually abandoned in favour of Gotham Knights — a title that failed to generate critical or fan acclaim. The letdown was followed by Suicide Squad: Kill the Justice League, another underwhelming effort from Rocksteady Studios. That same year, Warner Bros. also saw the lukewarm reception of Harry Potter: Quidditch Champions and the fizzling out of its crossover brawler MultiVersus.

The fallout didn’t stop there. In early 2025, Warner Bros. Games saw a major shake-up. Studio head David Haddad exited following widespread layoffs. Soon after, the company cancelled Monolith’s long-developed Wonder Woman game, shuttered Player First Games and WB Games San Diego, and announced a sweeping leadership overhaul. The focus now? Doubling down on proven franchises like Mortal Kombat, Harry Potter, DC, and Game of Thrones.

Even though Project Sabbath never made it to shelves, its lingering concept art and resurfaced footage keep fan curiosity alive — a haunting reminder of a bold new chapter for Batman that never got to turn the page.
