Batman Arkham Knight was released in 2015. It is now 2019 and we’ve gone almost half a decade without a decent Batman game. While Rocksteady Studios remains coy and secretive on what their next project could be, leaked concept art has reportedly revealed what would have been a Batman game featuring Damian Wayne from the folks at Warner Bros Montreal.

Code-named Project Sabbath, it’s unclear if this Warner Bros Montreal Damian Wayne Batman game would have been a sequel to Batman Arkham Knight or simply a standalone game. The original leaker of the concept art on 4chan claims that the cancelled game takes place in the future, sort of like a Batman Beyond-ish timeline with Damian Wayne instead of Terry McGinnis.

The concept features environmental art of a more gritty and desolate future version of Gotham (if that’s even possible). It’s different from the Neo Gotham we’re used to in Batman Beyond, that’s for sure.

Meanwhile, the other concept art depicts an older Two-Face, Poison Ivy, Gorilla Grodd, and a female Black Mask, as well as an older Dick Grayson who may or may not be Nightwing in this alternate future.
