As an original story (and something not connected to the Batman: Arkham series), Gotham Knights presents a new Gotham where Batman is seemingly dead (or missing). So, it's up to Batgirl, Nightwing, Red Hood, and Robin to step up to the plate... and protect Gotham from its rogues gallery of super-villains like Mr. Freeze.

With the "open-world third-person action RPG" due for release sometime next year -- 2021 for PC, PS4, PS5, Xbox One, and Xbox Series X -- we've also got the following 4K gameplay walk-through. Which shows Batgirl and Robin team-up to take on Mr. Freeze.

Gotham Knights is a brand-new open world, third-person action RPG featuring the Batman Family as players step into the roles of Batgirl, Nightwing, Red Hood and Robin, a new guard of trained DC Super Heroes who must rise up as the protectors of Gotham City in the wake of Batman’s death. An expansive, criminal underworld has swept through the streets of Gotham, and it is now up to these new heroes to protect the city, bring hope to its citizens, discipline to its cops and fear to its criminals. Players must save Gotham from descent into chaos and reinvent themselves into their own version of the Dark Knight.

“The team is thrilled to announce Gotham Knights and share our work in bringing a different story of the DC Super Heroes to the forefront,” said Patrick Redding, Creative Director, Warner Bros. Games Montréal. “We’re looking forward to fans playing and enjoying a lot of action as this new guard of strong DC Super Heroes in Batgirl, Nightwing, Red Hood and Robin, while solving an original mystery set against a living, breathing Gotham City.”

It certainly looks impressive from a visual and art direction standpoint, and the combat has a very Arkham feel which is more than welcome. Warner Bros. Games Montréal's last title Batman: Arkham Origins came out back in 2013, so this is also the long-awaited return for the studio.
