Batman: Arkham Knight was pulled from the shelves today, for the PC only.
On the official forum for the game, this was posted:
"Dear Batman: Arkham Knight PC owners: We want to apologize to those of you who are experiencing performance issues with Batman: Arkham Knight on PC. We take these issues very seriously and have therefore decided to suspend future game sales of the PC version while we work to address these issues to satisfy our quality standards. We greatly value our customers and know that while there are a significant amount of players who are enjoying the game on PC, we want to do whatever we can to make the experience better for PC players overall."
According to many reports, the game plays well on the PlayStation 4.
Forbes' contributing writer, Erik Kain, says the issue could stem from a lack of early PC testers for the game.
If you have the PC game, you can return it for a refund or wait for the patch to be developed.
