Announced in February 2013, it was released for Microsoft Windows, PlayStation 4, and Xbox One on 19 May 2015. The game is the third in the series, preceded by The Witcher and The Witcher 2: Assassins of Kings, which are based on the series of fantasy novels of the same title by the Polish author Andrzej Sapkowski, but all take place after them.

Played in a third-person perspective, players control protagonist Geralt of Rivia, a Witcher who sets out on a long journey through the large land of Northern Kingdoms. Players do battle against the world's many dangers using swords and magic, while interacting with non-player characters and completing side quests and main missions all to progress through the story. Players mostly travel by foot, and also on horseback on Geralt's horse 'Roach'."
