There’s going to be a Gotham Knights TV Show, tie-in comic, AND HBO Max movie...
Here is the article with information
The movie will have the 4 Bats as the main characters. It will feature the death of a Batman villain, and the team has to figure out who killed them, and Deathstroke will be a main antagonist. This looks to me that they want the movie to be different than the game (because they want to avoid spoiling the game, they’ll have a unique twist and ending).
However, the TV Show will feature other Batfamily/Batclan members that aren't the 4 in the Game/Movie. The plot is that a new/original character named Turner Hayes (Bruce’s adopted son) teams up with the children of Batman’s enemies to help protect Gotham after Bruce dies. The TV show is a spin-off of the Game. At first I thought they didn’t want to include the main 4 because of the other CW shows they’re in but I guess not, it must be because of the movie in development.
Oh yea there’s also going to be a tie-in comic for the game, I think people haven’t talked about it because they don’t know so here’s the info:
(The designs of the costumes confirm that it is Gotham Knights related)
This was accidentally leaked by artist Greg Capullo on Twitter, he quickly deleted it after. He is known for creating the Court of Owls with Scott Snyder, and I’m not really surprised that there’s going to be a comic alongside the game since DC has done that before with Batman: Arkham Knight. Having a comic (that could potentially be a prequel for the game) makes sense marketing-wise. The comic will have an official announcement soon because the tweet was not supposed to be posted early.
Tbh I’m not really a fan of the TV show/movie but I am excited for the game, and tie-in comic
Edit: I made a mistake of the movie plot details, because somehow I misread the article lol
