Thronebreaker is a single player role-playing game set in the world of The Witcher that combines narrative-driven exploration with unique puzzles and card battle mechanics.
Crafted by the developers responsible for some of the most iconic moments in The Witcher 3: Wild Hunt, the game spins a truly regal tale of Meve, a war-veteran and queen of two Northern Realms — Lyria and Rivia. Facing an imminent Nilfgaardian invasion, Meve is forced to once again enter the warpath and set out on a dark journey of destruction and revenge.
