Batman: Arkham Knight is no longer coming to Linux and Mac platforms, according to an announcement posted to Steam. Feral Interactive's port of the game, which was bound for Mac OS X, SteamOS and Ubuntu, has been canceled.
"We are very sorry to confirm that Batman: Arkham Knight will no longer be coming to Mac and Linux," reads an update posted to the game's Steam forums. "If you have pre-ordered Batman: Arkham Knight for Mac or Linux, please apply for a refund via Steam."
Feral Interactive, which ported Batman: Arkham Asylum and Arkham City to Mac, originally announced the non-Windows PC versions of Arkham Knight almost a year ago. The publisher delayed its Linux and Mac versions to spring 2016 in October — the same day the Windows PC version of Arkham Knight returned to Steam after being pulled from sale by Warner Bros. Interactive Entertainment.
