Minor Key Games co-founder David Pittman presents a detailed rundown of the theory and algorithms behind the procedural level design in Eldritch. How do you achieve a desired experience when level creation is offloaded to an algorithm? What role does a level designer play in a game with randomly generated levels? Why use procedural level design at all? David examines these and other topics through the lens of 3D action roguelike Eldritch. Attendees will learn how and why Eldritch's level generation was implemented, as well as general reasons why procedural algorithms might be embraced by level designers.
