It appears Batman and Wonder Woman are joining Superman and the Flash as the victims of who we presume is Brainiac in Suicide Squad: Kill the Justice League. We found this out in the latest trailer for the upcoming game by Rocksteady Studios. It also revealed that the latest installment in the Arkhamverse will posthumously feature Kevin Conroy, perhaps best known for voicing the Caped Crusader in several adaptations, including in Batman: The Animated Series as well as the vast majority of Batman's appearances across modern media.

Kevin Conroy passed away last month at the age of 66 due to the resulting complications from his undisclosed condition, colorectal cancer. Conroy had previously voiced Batman in all the Arkham games save for Arkham: Origins.

The latest trailer for Suicide Squad: Kill the Justice League also revealed the official release date for the game, May 26.
Suicide Squad: Kill the Justice League suffered several delays in the face of the pandemic. The original trailer came out at last year's DC's FanDome event and revealed that The Flash and Superman were part of the now-villainous Justice League. It's up to an unlikely bunch of villains to save the world. Harley Quinn, King Shark, Captain Boomerang, and Deadshot will make up the team's core. It wouldn't surprise us if other villains joined if only to get a cheapshot or two on the heroes without being put in jail.
Similar to Gotham Knights, Suicide Squad: Kill the Justice League will feature up to four-player co-op gameplay. Hopefully, the upcoming game won't suffer from the same issues that plagued Gotham Knights when it came out two months ago.
