The Witcher 3: Wild Hunt[b] is a 2015 action role-playing game developed and published by Polish developer CD Projekt and is based on The Witcher series of fantasy novels by Andrzej Sapkowski. It is the sequel to the 2011 game The Witcher 2: Assassins of Kings and the third main installment in The Witcher's video game series, played in an open world with a third-person perspective. Players control protagonist Geralt of Rivia, a monster slayer (known as a Witcher) who is looking for his missing adopted daughter on the run from the Wild Hunt, an otherworldly force determined to capture her and use her powers. Players battle the game's many dangers with weapons and magic, interact with non-player characters, and complete main-story and side quests to acquire experience points and gold, which are used to increase Geralt's abilities and purchase equipment. Its central story has several endings, determined by the player's choices at certain points in the game. Development began in 2011 and lasted for three and a half years. Voice recording took more than two and a half years. The writing was infused with realistic aspects such as moral ambiguity in an attempt to avoid simplification, impart authenticity, and reflect Sapkowski's novels. Central and Northern European cultures formed the basis of the game's world. REDengine 3 enabled the developer to create a complex story without compromising the game's open world. The music was composed by Marcin Przybylowicz and performed by the Brandenburg State Orchestra. The Witcher 3: Wild Hunt was released for Microsoft Windows, PlayStation 4, and Xbox One in May 2015, with a Nintendo Switch version released in October 2019. The game received critical acclaim, with praise for its gameplay, narrative, world design, combat, and visuals, although it received minor criticism due to technical issues. It received numerous Game of the Year awards and has been cited as one of the best video games ever made. Two expansions were also released to critical acclaim: Hearts of Stone and Blood and Wine. A Game of the Year edition was released in August 2016, with the base game, expansions, and all downloadable content. It was a commercial success, with the game and its expansions shipping over 28 million copies.
