Oh boy. When Batman: Arkham Knight got pulled from Steam in June due to a bad port, you'd assume that it wouldn't turn up again until the game was entirely fixed on the platform. I wouldn't have guessed the wait would be as long as October but hey, you gotta get it right.
Well, apparently that hasn't come to pass. The game is still experience massive performance issues, and has been ripped into by users and critics alike. Addressing this concern on the game's Steam page, it was revealed that Warner Brothers will be offering a refund to everyone who bought the game until the end of 2015. It doesn't even matter how long you've played the game.
It's a sad state of affairs and I'm sure it has opened up the refund policy to a lot of abuse, as people who completed the game and have tens of hours in game who have had no issues can now refund the game. Having said that, it does seem like the only option. There really does seem to be a problem with the game's very skeleton that makes fixing this version impossible. That is a rubbish place to be in for all.
