Satisfactory Update Adds Underground Building Mechanics

Satisfactory developer Coffee Stain Studios is expanding its first-person factory building game with a subterranean-focused add-on called Core Values, Teknikveckan reported. The Swedish studio announced the upcoming expansion during its Big Break Showcase, outlining a massive shift that takes industrial automation beneath the surface of the alien planet MASSAGE 2(A-B)b.

The Core Values expansion sends players deep into the bedrock of the planet MASSAGE 2(A-B)b. Rather than just a few isolated caves, the add-on introduces a comprehensive underground environment complete with its own unique resources, flora, fauna, and distinct engineering challenges. Players will automate production chains and build complex manufacturing networks beneath the existing surface world. Coffee Stain Studios designed the area to be accessible through a dedicated entrance once players clear the first phase of the base game, ensuring the content is open to players before they reach the endgame. Existing save files remain fully compatible with the new content.

Logistics and Transport Limitations Underground

Transporting materials between the surface and the new subterranean layer involves strict logistical hurdles. Coffee Stain Studios confirmed that neither work vehicles nor trains can be sent down into the underground region, forcing players to devise alternative transport methods for their resources. While the studio has no current plans to introduce underground subways or traditional mining transit systems, the expansion brings entirely new buildings and production chains. A new narrative unfolds gradually as players push deeper into the planet’s core.
