Coffee Stain Explains the Surprising Design Challenge Behind Satisfactory's Underground Expansion

Coffee Stain Studios discusses the complex balancing act of designing underground caves and spatial constraints for the upcoming Satisfactory expansion, Core Values.
Factory building games usually give players endless open skies and virtually infinite land to sprawl across, but Coffee Stain Studios is turning that formula upside down for the upcoming Core Values expansion. In a recent interview with Julian Benson over at Rock Paper Shotgun, the development team broke down the surprisingly complex math required to build underground caves that feel authentic and atmospheric while still containing massive production lines. Because the base game relies on handcrafted worlds rather than procedural generation, every resource node and natural bottleneck is intentionally placed. Shifting that philosophy underground means the team has to meticulously calculate everything from building sizes and recipe costs to how players will actually route their power grids and assembly lines in tight quarters.
The core design problem comes down to a balancing triangle between cave geometry, required factory scale, and machine footprints. Game director Emmet Burke and art director Torsten Gunst explained that the team constantly tests different factory layouts across entire biomes to anticipate how players will progress through the tech tree. If a cave is too restrictive, players lose the creative freedom that makes automation games so satisfying. If it is too cavernous, it completely ruins the claustrophobic atmosphere of exploring an alien underworld and removes the logistical puzzle of working within strict spatial limits.
Of course, developers can never fully outsmart the absolute masters of optimization who play these games. Coffee Stain knows the community will inevitably find hyper efficient factory layouts and bizarre architectural workarounds the team never even simulated during testing. To account for different playstyles, the studio added a generous buffer of extra cave space for players who prefer sprawling, chaotic builds over hyper optimized perfection. It is a fascinating look behind the curtain at how level design has to adapt when players treat a quiet sandbox as a canvas for monumental industrial engineering.
