In another update on the Batman: Arkham Knight steam page, Yorick of Warner Bros apologizes to players still not satisfied with their version of the game. He states that Warner Bros will offer a full refund to players until the end of 2015.
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.
The time is now if you want to back out of the PC version and settle for the PlayStation 4 or Xbox One. Season passes and the main game can be returned as well, but not separately.
