""The PC port of Batman: Arkham Knight continues to be a comedy of errors. In spite of numerous patches, a complete relaunch, and loads of promises, the game still performs poorly on a wide range of PCs. Even with an extra four months to tidy up the mess, the developers still can’t get the game to run reasonably well. After yet another tidal wave of negative customer feedback, Warner Bros. has caved, and is now allowing for complete refunds until the end of the year.
In a message posted on the Arkham Knight Steam community page, a Warner Bros. representative announced that every owner of the PC version will be able to return the game for a full refund. Regardless of how many hours you’ve played, you can get all of your money back until the end of the year. Did you buy the season pass as well? You can return that too, but only if you decide that you’re willing to part with the core game as well — no backsies otherwise.""
