Newly leaked footage has surfaced online, revealing a glimpse of an unfinished Batman game that would have put Damian Wayne — the son of Bruce Wayne — in the cape and cowl. The footage, tied to the long-rumored Project Sabbath, offers a rare look at a scrapped entry in the acclaimed Arkham series developed by Rocksteady.

The video, shared by The Arkham Channel, features a dramatic motorcycle chase between Batman (Damian Wayne) and a visibly monstrous Killer Croc. The sequence appears to be part of an early build, with several textures and assets still in development — many buildings lack detail, and Killer Croc’s model is noticeably borrowed from Batman: Arkham Origins. Despite the placeholder elements, the footage provides a rough but intriguing look at the direction Rocksteady was aiming for before the project was shelved.

This isn't the first time Project Sabbath has come up. Concept art from former WB Games Montréal artist Rodrigue Pralier recently surfaced, showing off various character designs including an older Bruce Wayne, the Huntress, and several takes on Killer Croc (check it out here). These visuals already gave fans something to chew on, but now the video adds a new layer of depth — offering a feel for gameplay, tone, and narrative direction.

The game was reportedly set in a future Gotham, ten years after the events of Batman: Arkham Knight. In this world, Bruce Wayne has stepped down due to age and injury, passing the torch to his son Damian. Unlike previous Batman games, Project Sabbath aimed to explore the legacy of the Dark Knight from a new generational lens, possibly drawing influence from Batman Beyond while still rooted in the Arkhamverse.

Rocksteady’s Batman: Arkham Asylum first launched in 2009 and was widely praised as a genre-defining superhero title. Its tight gameplay, atmospheric design, and strong narrative made it a standout, eventually leading to Arkham City and Arkham Knight. WB Games Montréal also contributed with Arkham Origins. Collectively, the series set a high standard for comic book games, so the idea of a Damian Wayne-led sequel sparked serious curiosity among fans — even if it never made it past early development.

According to reports and speculation over the years, Project Sabbath included not just Damian Wayne and Bruce, but a cast of familiar and reimagined characters. Huntress was expected to play a supporting role, and villains like Poison Ivy and Two-Face (in his alternate “The Judge” persona) were allegedly planned. The recent concept art also suggested bold design choices — especially with characters like Killer Croc appearing more humanoid or even alien-like in some drafts.

The project was eventually scrapped, with WB Games Montréal focusing instead on Gotham Knights, which released in 2022. Meanwhile, Rocksteady moved on to Suicide Squad: Kill the Justice League, a game set in the same universe as Arkham but with a very different tone and gameplay style. Unfortunately, that title failed to replicate the success of the Arkham trilogy, with fans and critics alike pointing out its live service elements and lack of the narrative weight that made the earlier games special.

While Warner Bros. has not publicly commented on the leaked footage, the growing pile of assets from Project Sabbath — between concept art and gameplay — paints a picture of a game that could’ve taken the franchise in an exciting, fresh direction. Whether this renewed interest will inspire the publisher to revisit the idea remains to be seen.
