A Steam Community Group Announcement from Warner Bros. Interactive Entertainment has word that the Windows edition of Batman: Arkham Knight should go back on sale by the end of this month along with the release of a new patch for the action/adventure (thanks GameSpot). Sales of the superhero sequel were suspended in June due to bugs and performance issues, and they've been working on getting things into proper shape since then. Here's word:

As many of you know, we released a major patch for Batman: Arkham Knight PC a few weeks ago. While there were significant performance improvements made to the game, the teams are continuing to work on the additional updates that were outlined in our previous post. We expect these updates to be ready at the end of October, at which time the PC version will be made available for purchase. In addition, support for all DLC that has been released for the console versions will be in place.

Thanks again for your continued patience and support. We’ll be sure to update everyone as soon as the update is live.
