The game originally launched on PlayStation 4, Xbox One, and Windows PC in September 2018, published by Square Enix and developed by Eidos-Montréal. Shadow of the Tomb Raider picks up the story from the 2015 entry in the series, Rise of the Tomb Raider, and follows Lara Croft as she hunts for the legendary hidden city of Paititi in the jungles of South America, battling the Trinity organization and attempting to prevent a Mayan apocalypse.
Shadow of the Tomb Raider will follow Rise of the Tomb Raider's appearance on macOS earlier this spring, in the form of the "20 Year Celebration" edition of the game that included all DLC content. Feral announced Rise of the Tomb Raider would be coming to Mac in February and then launched it in April, so we should hear more about a specific launch date for Shadow of the Tomb Raider after the new year.
Feral also ported the original rebooted game, simply titled Tomb Raider, to macOS and Linux computers.
