Even with a few months of furious fixing under its utility belt, the PC version of Batman: Arkham Knight is still disappointing cape enthusiasts everywhere with its dodgy performance and stability. With little recourse after suspending sales on Steam while emergency work was conducted, publisher Warner Bros. is now offering refunds for the game and season pass to all comers.
No problem if you've owned the game / played it for longer than two hours, you can still get a refund, as is explained in the following post on Arkham Knight's community hub:
We are very sorry that many of our customers continue to be unhappy with the PC version of Batman: Arkham Knight. We worked hard to get the game to live up to the standard you deserve but understand that many of you are still experiencing issues.
Until the end of 2015, we will be offering a full refund on Batman: Arkham Knight PC, regardless of how long you have played the product. You can also return the Season Pass along with the main game (but not separately). For those of you that hold onto the game, we are going to continue to address the issues that we can fix and talk to you about the issues that we cannot fix.
Sadly it seems Arkham Knight on PC is a lost cause -- hopefully Warner and Rocksteady can learn an important lesson from the disaster, both in terms of PR and sales. Not sure if there's much either party can do about the loss of consumer confidence however.
