The Witcher 3: Wild Hunt is an action role-playing video game set in an open world environment, developed by Polish video game developer CD Projekt RED. It was released for Microsoft Windows, PlayStation 4, and Xbox One on 19 May 2015. The game will be 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. The Witcher 3: Wild Hunt concludes the story of the witcher Geralt of Rivia, the series' protagonist, whose story to date has been covered in the previous versions. Continuing from The Witcher 2, the ones who sought to use Geralt are now gone. Geralt seeks to move on with his own life, embarking on a new and personal mission whilst the world order itself is coming to a change. Geralt's new mission comes in dark times as the mysterious and otherworldly army known as the Wild Hunt invades the Northern Kingdoms, leaving only blood soaked earth and fiery ruin in its wake; and it seems the Witcher is the key to stopping their cataclysmic rampage. On 7 April 2015, CD Projekt RED announced two expansion packs for the game titled Hearts of Stone and Blood and Wine. Hearts of Stone was released on October 13, 2015, and Blood and Wine was released on May 31, 2016..
