Batman: Arkham Knight publisher Warner Brothers has issued a statement apologizing for the game’s numerous problems on the PC. The company says that as fixing the computer version of the game is a top priority right now, all downloadable content for the platform will be put on hold.

The decision to delay the first Arkham Knight DLC on the PC has not come as a surprise, especially as the game is not being sold on the platform at the moment; it shipped with so many performance issues on the PC, Warner Brothers was forced to pull the game from sale. It was also reported that the company knew of Arkham Knight’s technical issues months before its launch, but chose to ignore them in order to focus on improving the console version.

Warner Brothers states that because of the problematic Arkham Knight PC launch it is modifying its internal review process for all games.

We are taking full responsibility for releasing a product that did not meet our quality standards, which is why we suspended sales of the game as soon as we understood the issues. The Batman: Arkham Knight fans are extremely important to us and our highest priority is ensuring PC users get the full, high quality experience of Batman: Arkham Knight they deserve. [...] We can also assure you that because of this latest launch, we are modifying the internal review process for all of our games. For those who are waiting for the updated version of the game on PC, please know that we are working on this every day. For the players who are continuing to play Batman: Arkham Knight on PC, fixes are continually being made to the game as we await the final updated version.

The first DLC pack for Batman: Arkham Knight will be released for the Xbox One and PS4 on Tuesday, July 14. The Batgirl: A Matter of Family expansion is set prior to the events of Batman: Arkham Asylum and features a playable Batgirl character.
