We encourage anyone who’s been on the fence about the game to check out the demo and to begin their adventures in the world of The Witcher. We advise that users from United Kingdom, Germany, Italy and France should use a link to the E-shop, people from other countries should check a direct link from Metaboli. Links currently don't work for people in United States - the appropriate ones will be given as soon as possible.
