— Everything you need to know
Batman: Arkham Knight is almost here, so we've collected the most important details in one place for convenience. We'll keep this page updated with all the latest before and after release.
The Batman has gone through the wringer in the Arkham series. Every game he starts with a nice clean suit, but it always ends up torn and scuffed from combat with Gotham's ceaseless stream of evil loons. Some like to argue that the first game, Arkham Asylum, is still the most perfectly formed package of the four. Those people might worry about Arkham Knight's move towards an even bigger and prettier city. Much stays the same, however. Batman still smoulders with the quiet, authoritative anger of returning voice actor, Kevin Conroy, the goons are still improbably ripped and villains still love to taunt Batman by radio, or by projecting their ugly faces onto huge screens scattered throughout Gotham.
There's going to be another mini-Batcave to house the Dark Knight's new gadgets, and there we'll even meet Oracle in person.
Most recently, the DLC and season pass were revealed, including the opportunity to play as Batgirl, and we got a trailer and a bunch of new screenshots.
What's the release date?
Arkham Knight was due to arrive in 2014, but Warner Brothers have delayed the game a couple of times since. It's now due out worldwide on June 23, 2015, unless the Joker throws a wrench in the works.
What's it about?
You once again step into the armoured kicking-boots of the world's greatest detective on the eve of a city-wide disaster in Gotham. Citizens have fled after a series of fear-gas attacks organised by Scarecrow, leaving the GCPD and Batman to police a city five times the size of Arkham City's playable area.
The Batmobile—
drivable for the first time in the series—ought to help, but Batman's new armoury will be tested by a dastardly squad of classic villains, and one entirely new one called the Arkham Knight. Rocksteady describes this as the “finale” to their trilogy, quietly discounting Warner Brothers Montreal's Batman: Arkham Origins from the series.
Arkham Knight should make sense to players who haven't played the other Arkham games, but there's already a lot of history between Batman and the returning villains, and the conclusion of Arkham City will definitely influence Batman in Arkham Knight. For that reason, City's the one to play if you want to prepare yourself, followed by Arkham Asylum, followed by the average prequel, Arkham Origins. The Arkham Wiki has a comprehensive plot summary of the entire series if you're rather read your way in.

Who are the villains?
The “Gotham is Mine” trailer showed a broad spectrum of famous bad guys. Poison Ivy, The Penguin, Scarecrow, Firefly, Harley Quinn, Two-Face and The Riddler have all turned up in the Arkham series before, and will appear again. Their roles in the grand conspiracy aren't known yet, but The Riddler will run underground race tracks as part of a series of challenge caves.
The Arkham Knight is a new villain created by Rocksteady in collaboration with DC. Not much is known about him yet, but we have a few crazy theories about his identity. He's shown standing at the front of an automated army of drones and tanks, which you'll have to take out using the Batmobile's completely non-lethal roof-mounted cannon.
Who are the heroes?
Batman won't be alone. Robin, Nightwing, and Catwoman turned up in the “All Who Follow You” trailer which also shows Batman performing some acrobatic co-operative takedowns. This is part of a new “Dual Play” feature which Rocksteady says will “allow players to seamlessly switch between The Dark Knight and his allies” in combat. Azrael also turns up briefly in that trailer, but it's unclear whether he will be playable, or do much other than start fires on rooftops and mumble about “the prophecy”.
There's more. Batgirl will be playable in Arkham Knight's post-launch DLC plan and the Red Hood “story pack” is available as part of a pre-order DLC pack. She's no hero, but Harley Quinn gets her own pre-order DLC mission as well. Batman: Arkham Knight has a lot of DLC.
Have you played it?
Sam's piloted the Batmobile through Arkham Knight's refined and greatly-expanded version of Gotham city, but only fell in love when he found out you can use it to help you in fights and pull down walls. He also discovered the new contextual combat moves which see Batman ramming his enemies heads into environmental hazards like live fuse boxes. Non-lethally, of course.
What's happened recently?
A live action trailer was released.
Rocksteady dropped a few details about their expensive post-launch DLC plan, which includes a mission that lets you play as Batgirl.
The wallet-busting premium edition was announced.
The game was slightly delayed from early June to late June. We blame Calendar Man.
Batman: Arkham Knight is rated M, so expect fiercer punching this time round.
What are the best trailers?
The seven-minute "Officer Down" trailer, and the recent "Time to go to War" trailer below, most clearly show how the game will play, and give us a better look at the city than the cinematic trailers. The Ace Chemicals Plant walkthrough gives a good account of how the Batmobile can help Batman solve environmental puzzles (and also shows lots of punching). The rousing "Gotham Is Mine" trailer lays out the stakes nicely. And then there's this live action trailer. Huh.
What are the system requirements?
Arkham Knight's system requirements are demanding, especially if you're keen to run the game on ultra settings. That 55GB install's going to eat up a big chunk of space if you're running an SSD.
