Kingdom of Night is an adventure RPG with an isometric camera view and horror elements. In the game, you have to infiltrate the sinister lairs of five demon lords to save the world from the apocalypse. As you progress, you will fight various monsters, improve your abilities and collect the necessary equipment. The main quest involves defeating five demon generals and gaining access to Baphomet's fortress, Leviathan. After the game's first introductory chapter, which is called midnight, the entire map of Watford is revealed to the player, and the five demon generals can be defeated in any order. When you start the game, you can choose one of 9 classes. The class you choose determines your base playstyle, while skill trees allow for further customization. Rather than balancing all classes, each class is weighted differently, giving each a unique playstyle.
