The game series is based on a series of short stories and novels written by Andrzej Sapkowski in Polish. The first book of short stories introducing the Witcher Saga and the first novel in the series, The Last Wish (Polish: Ostatnie życzenie) and Blood of Elves (Polish: Krew elfów) respectively, have been translated to English and are available in print and various e-reader editions.
The first game in the series, The Witcher, released on PC was in development for Xbox 360 and PS3 until April 2009 when developer CD Projekt RED announced that the project had been put on indefinite hold. The second game in the series, The Witcher 2: Assassins of Kings, released on PC May 17, 2011 and on Xbox 360 on April 17, 2012. The third major entry in the series, The Witcher 3: Wild Hunt, was released on May 19, 2015 for PC, PS4, and Xbox One.
The games follow the Witcher, Geralt of Rivia, as he struggles to regain his memories and prevent the Wildhunt from destroying the world. Amnesia is used to both allow the player to make choices the Geralt from the books would not have made and to allow the game developers to explain aspects of the universe to those who have not read the book.
