How a Four-Person Programming Team Built Clair Obscur: Expedition 33

At GDC 2026, Sandfall Interactive revealed that 95 percent of Clair Obscur: Expedition 33 was built using Unreal Blueprints rather than custom C++ code, showcasing how a tiny team of four programmers pulled off a massive RPG.
During this year's Game Developers Conference, Sandfall Interactive pulled back the curtain on how they managed to build Clair Obscur: Expedition 33 with an exceptionally lean programming crew. In a detailed panel session, technical director Tom Guillermin and senior gameplay programmer Florian Torres revealed that a staggering 95 percent of the game's gameplay systems were built entirely using Unreal Blueprints, with the team writing almost no custom C++ code of their own.
For those following development trends, this approach highlights a massive shift in how modern studios punch above their weight class. Unreal Blueprints allow developers to connect pre-built visual scripting nodes to create complex mechanics, bypassing the traditional bottleneck of writing heavy lines of code from scratch. This toolset was vital for Sandfall Interactive, especially since the entire game was initially prototyped by just a single programmer before scaling into a broader hit.
Stories like this matter because they point toward a more sustainable future for game development, proving that massive, visually striking titles do not always require hundreds of engineers working in silos. By leaning into modular developer tools, smaller studios can focus their energy on creative direction, world-building, and player experience rather than reinventing the technical wheel.
