You have to be quick as it is only a technical beta of the game.
While PC and Xbox One players are able to play Gwent: The Witcher Card Game on a daily basis, PlayStation 4 was clearly absent from the CD Projekt RED’s schedule. But it’s no longer the case as the technical beta is live on PlayStation Network.
Gwent’s technical beta will end on April 3rd at 2AM EDT/ 8AM CEST. You are not able to use microtransactions and the developers will reset your progress. There’s no word if the game will receive a PC/XO-alike version anytime soon.
