Batman: Arkham Knight is the highly anticipated fourth and final instalment in the Batman Arkham series, which was released for PC, Xbox One and PS4 on 23 June. However, launch day issues with graphics led Warner Brothers Games to suspend sales of the PC version, and eventually to offer full refunds when the issues were not resolved. We've gathered together everything you need to know about Batman: Arkham Knight in this article, including the game's release date, gameplay features, trailer and official screenshots.

Batman: Arkham Knight issues: AMD & Nvidia graphics cause PC sales suspension

Shortly before Batman: Arkham Knight was set to arrive, developer Rocksteady updated the system requirements for the game, immediately sparking concern about PC graphics issues. And it wasn't long after the midnight launch that it was discovered that AMD and Nvidia graphics cards are being plagued with issues, leaving many players who've been waiting months for this game feeling disappointed. Things took a turn for the worse, and PC sales of the game were suspended until Warner Brothers could resolve the issue.

On the Warner Brothers Games forum on 22 June, the eve of the game's launch, the admin wrote: "We also want to note that there are some known issues with the performance of Batman: Arkham Knight for PC owners using AMD graphics cards. We are working closely with AMD to rectify these issues as quickly as possible and will provide updates here as they become available. Thank you for your patience in this matter."

Issues reported over on Steam include framerate issues, poor image quality causing bugs such as stuttering, flickering and crashes and more.

AMD issued an AMD Catalyst 15.6 Beta Windows Driver to bring performance and stability improvements for Batman: Arkham Knight, but it meant that AMD Crossfire support would be disabled until the underlying issues were resolved.

Known issues prior to the installation of the driver include crashes and black or pink screen issues.

Nvidia also issued a GeForce Game Ready Driver for Batman: Arkham Knight, but gameplay was locked to 30FPS which caused a bit of an uproar, to say the least.

You can see a list of the updated system requirements below.

On 25 June, just days after the launch of Batman: Arkham Knight, Warner Brothers has decided to suspend sales of the game on PC through Steam due to major technical issues. It came as a massive blow to gamers who've been waiting for this game for so long – it was already delayed from its originally intended October 2014 launch last year. 

"We want to apologise to those of you who are experiencing performance issues with Batman: Arkham Knight on PC," reads a message from Warner Brothers on the Steam Community Batman forums. "We take these issues very seriously and have therefore decided to suspend future game sales of the PC version while we work to address these issues to satisfy our quality standards. We greatly value our customers and know that while there are a significant amount of players who are enjoying the game on PC, we want to do whatever we can to make the experience better for players overall."

"We are aware that there are performance issues for some users playing Batman: Arkham Knight on PC. WB Games is working diligently with our development teams, Nvidia and AMD, to identify and fix the issues as quickly as possible."

Warner Brothers says that it is monitoring all threats posted in the Official Batman: Arkham Knight Community and Steam forums, as well as any issues logged with its customer support.

Batman: Arkham Knight PC release date: When is Arkham Knight coming back to PC?

Batman Arkham Knight returned to PC on 28 October 2015. Unfortunately, issues remain.

According to Gamespot, "the re-released PC version still has numerous performance issues ranging from stuttering to DLC compatibility".

Warner Brothers has now pledged to give all PC users who have bought Batman: Arkham Knight a full refund. It will, however, continue to patch the game for those who don't opt for their money back.

How to get a refund for Batman: Arkham Knight

If you're not satisfied with your experience of the new Batman game on PC, you can request a refund through Steam.  

To do so, you'll need to visit the Steam Help page, and sign in to the Steam account you used to buy Batman: Arkham Knight.

Them, go to Games and Applications and choose Batman: Arkham Knight. You should see two options: I can't successfully purchase and Gameplay or technical issue.

Choose the second option, and then click Request a refund on the right.

Steam's refund terms and conditions state that the player needs to have spent less than two hours playing the game, and as far as we can tell those terms still apply, but we'll update this article if an exception is being made in this case.

Warner Brothers has also said that you'll be able to request a refund from the retailer you purchased the game from, but we imagine the success will depend on the shop. Let us know if you've successfully got a refund in the comments section at the bottom of this article.

Batman: Arkham Knight release date: When is Batman: Arkham Knight coming out?

After being announced in March 2014, Batman: Arkham Knight was released worldwide on 23 June 2015 for Microsoft Windows, PS4 and Xbox One, followed by an OS X release later in the year.

That release date came as a major blow for many eager fans, who were expecting the game to arrive on 14 October as part of the 75th anniversary of Batman in 2014.

"If we didn't give the team more time to do it, then we would be releasing something that we weren't happy with," explained developer Rocksteady's marketing game manager, Guy Perkins. "We want to make sure we're absolutely nailing it 100 per cent." (Something tells us it didn't quite manage that...)

Batman: Arkham Knight for Wii U, Xbox 360, PS3

Despite the previous games being available on Wii U, there's no Wii U version of Batman: Arkham Knight in the works, and the same goes for PS3 and Xbox 360. Rocksteady has said that this is due to the technology, because compromises would have needed to be made to the gameplay, particularly the Batmobile, that the developers weren't happy about.

The main story of Batman: Arkham Knight is set one year after the events that took place in Batman: Arkham City, and sees Batman confront enemy Scarecrow, who's trying to unite all of Batman's enemies in an effort to kill him. Those enemies include Penguin, Two-Face, Harley Quinn and Riddler.

It's once again set in Gotham City, but this time, the scale of the city is approximately five times bigger than it was in Batman: Arkham City.

Now, here's the really exciting news: Batman: Arkham Knight will feature the Batmobile.

Not only will players be able to use the Batmobile as a new mode of transport in Arkham Knight, it can also be used as a weaponised tank.

According to Perkins, the Batmobile has been "at the heart" of the design of Arkham Knight. "It's informed how big the city is, how wide the streets are, how you navigate through those," he said. "And introducing it with the two modes [combat and puzzle], again, every design decision was made around that."

"The Batmobile is another character almost in that it works with Batman and augments his abilities in different ways," Perkins added. "You can puzzle solve; you can engage in combat. You're never more than a button press away from the Batmobile. It's a partnership – we never want people to feel that this is a very specific Batmobile section and that this is a very specific Batman level. We want them to ask: 'How will the two work together?'"

It's a single player game with no multi-player element.

Batman: Arkham Knight has been rated 'M' for Mature rather than 'T' for Teen like the previous games in the franchise. The developers are said to have been caught off guard by the rating. "It's unavoidable that some bad stuff is going to happen," said director Sefton Hill of the game. "But that doesn't mean we changed our approach. We're not including gratuitous blood or swearing. We want to deliver a true end with no compromises, and it takes us to some dark places."

Those "dark places" are believed to involve torture on a "bloody operating table," and a scene in which players can shoot unarmed characters and a hostage.
