London-based video game developer Rocksteady Studios is working on “Batman: Arkham Knight,” the final installment to the “Arkham” trilogy as if “it’s the last” game the studio will ever make.

“We’ve always had the philosophy that little details are what make a game truly immersive,” game director Sefton Hill told GamesTM this week.

“I think that’s one of the strengths of our earlier games. We’ve finally got the chance to show what the whole of Gotham City looks like in the Arkhamverse, and it’s huge: full of massive skyscrapers, dark grimy alleyways and glaring neon. And rain – we’ve spent a lot of time making the rain feel just right! The sun hardly ever shines in Gotham, and switching to new-gen consoles has made it possible for us to bring that unique atmosphere to life in a way that hasn’t been done before in gaming.”

"Arkham Knight" will be a single-player game and the fourth installment in the series. It is set to be the final chapter in the “Arkham” games. Kevin Conroy, 58, will return as the voice of Batman. Conroy also portrayed the Dark Knight in “Batman: Arkham Asylum” and “Batman: Arkham City.”

The game’s storyline takes place one year after 2011’s “Batman: Arkham City” and the death of the dark knight’s arch nemesis, the Joker. “Arkham Knight” will allow players to drive the Batmobile, a feature that was left out of previous games in the franchise. The title will only be available on the Xbox One, PlayStation 4 and PC.

“The new technology has given us the chance to apply our detailed approached to a much bigger, open world,” Hill added.

“Our version of Gotham is teeming with life. While it has been evacuated, it has been completely occupied by the gangs of Gotham, and the Arkham Knight’s militia army. There are also many more of Gotham’s Most Wanted who’ve crawled out of the woodwork in this coordinated attack to bring the Batman to his knees.”

Though the Joker will be absent from “Arkham Knight,” more villains from the DC comic will appear in the game, including Harley Quinn and the Scarecrow.

“Ever since Batman: Arkham Asylum, our approach has been to put everything we have into every game we make,” Hill continued. “We never hold ideas back because you never know what’s around the corner. So I guess you could describe that as a ‘kitchen sink’ approach, but I’d prefer to say it’s more of a ‘live every game as if it’s your last’ approach (mainly because it sounds more poetic).”
