About Valor Mortis
Developed by One More Level, the Kraków studio behind Ghostrunner, and published by Lyrical Games, Valor Mortis released on October 13, 2026 for PC via Steam, PlayStation 5, and Xbox Series X|S. It moves the soulslike genre into first person and into an alternate-history 19th century. You play William, a soldier of the Grande Armée raised from a corpse-strewn battlefield into a Europe he doesn't recognise. A mysterious plague is sweeping the continent, and the same corrupting power now runs through his veins. As you fight through the abominations of Napoleon's Eternal Guard, you uncover a conspiracy that blends real historical figures with horror and the supernatural.
Combat is built around precision. You manage stamina, land parries and dashes, finish enemies with visceral finishers, and choose between a variety of weapons, while your supernatural power adds abilities that you unlock as you go. Every death is a chance to grow stronger, since the game ties your progression to the corruption you carry. The levels reward exploration, with environmental secrets that can improve your chances of survival, and the story pushes you beyond the dark corners of the world to learn the truth behind the plague and your resurrection.
