From the developer:
GWENT is a card game of choices and consequences, where skill, not luck, is your greatest weapon. Pick a faction, build an army, and wage war against other players across multiple game modes. With hundreds of cards to collect - charismatic heroes, mighty spells and special abilities - new strategies are always a thought away.
