Those anticipating to get back into The Witcher universe with story content for GWENT The Witcher Card Game will have to wait a bit longer than anticipated.

Earlier today, CD Projekt Red confirmed that the GWENT The Witcher Card Game first single-player, story-driven campaign Thronebreaker has been delayed to 2018. As the team decided to increase the campaign’s scope, more development time is needed.
