(Pocket-lint) - When Batman: Arkham Asylum first came out it redefined superhero games.

Its crunching, combo-based combat and fun exploratory navigation made for a heady gameplay blend. It was then followed by two, ever more excellent outings, Arkham City and Arkham Knight, each of which widened the series' scope. And a prequel game, Arkham Origins, filled out the quadrilogy.

Now, after a five year hiatus, a fifth game with similar gameplay is heading our way - Gotham Knights - although it isn't actually set in the Arkham Universe.

Instead, it is an original story based in the normal DC Batman Universe, and rather than focusing on the Dark Knight himself, it centres on four of the extended Bat family: Batgirl, Robin, Nightwing and Red Hood.

Here is what we know about it so far, the debut trailer and more. Enjoy.

Gotham Knights release date

After being heavily rumoured for months, Gotham Knights was fully unveiled during DC FanDome at the end of August 2020.

A "world premiere" trailer was released (which you can see below), which also revealed that the game is due in 2021. Sadly, there's nothing more specific than that at present.

Gotham Knights trailer

As previously stated, the world premiere trailer was released as part of DC FanDome in August.

In it, you get to see the new cast of playable characters - with Batman presumed dead. The multiple leads also makes for an interesting jump-in, jump-out co-op experience.

Gotham Knights plot, characters and villains

WARNING: SPOILERS AHEAD!!!

Batman is dead, presumably.

Gotham, however, is still at risk of super-villainry, so up steps the usually supporting cast of Bat family members: Bat girl, Robin, Nightwing and Red Hood.

Players get to take on each of the characters (sometimes two at once, in co-op), with different abilities at their disposal.

Batgirl (Barbara Gordon, who was previously Oracle) is the most like Batman himself, with an array of martial art skills.

Nightwing is the first Robin Dick Grayson, who wields dual Escrima Sticks to help take out enemies.

Red Hood is also a former Robin, Jason Todd, who is more fond of using guns and tech to get his way. He's also the biggest indication that Gotham Knights is not set in the Arkham universe, as Todd turned out to be the eponymous Arkham Knight in that timeline.

Finally, Robin, Tim Drake, is more stealth focused than the others.

They will have to take on several key villains from the comic books, including Mr Freeze (seen in the gameplay walkthrough below) and the shadowy figures of the Court of Owls.

Gothams Knights gameplay

While Gotham Knights is not based in the Batman Arkham universe, it features similar gameplay - as evidenced by a walkthrough video released during DC FanDome.

Each of the playable characters will have their own unique styles, but the open-world landscape of Gotham will feature storyline missions and, seemingly, side quests - much like Arkham City and Arkham Knight.

The biggest addition is two-player online co-op. While the game will be able to be played in single-player in its entirety, a couple of players can take on different lead characters and play together.

Gotham Knights platforms

Gotham Knights will be available for PS4, Xbox One and PC. It will also launch on Playstation 5 and Xbox Series X, taking advantage of next-gen's beefed-up graphics and faster loading times.

There is no confirmation of a Stadia version at present.
