"No belts here": Satisfactory's first expansion isn't just the same game underground - it introduces a fresh toolkit for moving resources

Spoiler warning: this article does not reveal major story turning points or endings from Satisfactory.

Background: Years of Surface Factories Shape the Expansion Question

Satisfactory opens with a player in a drop pod falling toward an alien world. Its main game asks players to build factory automation across open terrain, using belts, machines, and research steps to move resources from one point to another. Because players can spend years optimising a base, Coffee Stain's first expansion, Core Values, is designed around a practical concern: how should an underground mining operation connect to existing surface economies without letting old factories simply blitz through every new challenge?

Development Process: Core Values Is Not the Same Game With the Lights Off

Core Values is set entirely in an underground biome. It asks players to build a thriving mining operation in a world limited in space and light, where moving through tunnels itself becomes a challenge. Coffee Stain stresses that the expansion is not just Satisfactory with the lights turned off. It brings a new set of logistics tools and new problems, so getting resources from mining point A to refining point B will not always be as simple as sending them down a conveyor belt.

When Coffee Stain first introduced Core Values, it explained that an expansion connected to the base game has to account for players who already have mature factories pumping out resources and components. If those inputs could be funneled underground too easily, the new challenges could be skipped.

One early speculation was that the cave might simply make ordinary concrete unusable, then ask players to build a similar but distinct concrete-like substance for new belts. That would force a familiar research and development loop again. The developers did not present that as their answer.

Game director Emmet Burke says some logistics from the base game will remain, and players will still use the same ingredients to build them. Belts will be present, but Core Values will add other logistics unique to the underground space. Art director Torsten Gunst says a new underground resource that simply becomes the material for belts would not feel rewarding. New resources should open new logistics and expand the game. He adds that the team is not cheaping out and that a lot of new content is coming.

Burke also describes a change in machine character. Base-game machines are precise, like refined supercomputers. Core Values uses more rugged, heavy machines, with big grinding gears and hammers striking resources. That language points toward industrial handling such as mine carts, cranes, and load, haul, dump machines, although those are not confirmed by Coffee Stain.

If those new logistics behave differently from existing belts and trucks, the resources they carry may also need to behave differently. In the original Satisfactory, resources outside storage lockers are presented as easily transported boxes that players cannot physically interact with. A change to material that can be heaped, spilled, or toppled would be radical. Loose materials like those seen in Sandustry could point in that direction, but Coffee Stain did not confirm this, and such a change may be too significant for an expansion.

Space and Light: Caves Remove Surface Freedom

On the surface, factories can sprawl across large open fields. They can be tall, wide, and wasteful. A cave changes that. Burke says the team wants to be careful about how much space it gives different players, because the area must still feel like a cave. Small tunnels should remain worth exploring, and there should be enough room for creative factory layouts, but the expansion should not become a big box where anything can be placed anywhere.

Light is the second pressure. Once natural light is gone, players must both see and orient themselves. The underground setting makes navigation more complex than surface travel, where a nearby base can often be seen or circled.

Navigation Challenge: 20 Metres Can Hide Behind a Granite Wall

Burke gives a concrete example: a HUD compass might show that the player is only 20 metres from a hub, but if a cave wall lies between them, the arrow pointing directly at a granite barricade is not helpful. He calls this a tricky design problem.

Coffee Stain partially addresses it with cave landmarks. Waterfalls and crevasses can serve as visual points to navigate by. The rest is left to the player. Gunst says players can place sign posts, follow their own pipe system, or mentally map the cave from the machines they have placed. He adds that navigation and orientation are part of the fun, but the expansion should not become a hardcore challenge, because players still need to do the job of building factories.

Latest Progress: A Reveal Under Embargo, Then More Community Detail

The first written look at Core Values was produced under embargo and published after the reveal. The initial reaction to the underground setting was cautious. A cave can sound like just another large underground room, and no shown detail at that point fully dispelled that worry. The developers declined to reveal more, but their insistence on new logistics, limited space, and player-side orientation left curiosity about how cave factory building will differ from surface construction.

Burke said that after the reveal, the team will be much more active with the community again. The planned next steps include posts detailing new features, videos showing the expansion in action, and a return to the kind of relationship Coffee Stain had with players during early access. The Gamescom coverage was produced with travel and accommodation provided by the conference organisers.

Current Stage: Core Values Is Announced, Not Fully Explained

Core Values is now positioned as Satisfactory's first expansion and as an underground logistics test. The confirmed facts are the underground biome, the mining focus, limited space and light, continued use of some base-game ingredients, new unique logistics, rugged machinery, and a navigation problem illustrated by the 20-metre cave-wall example.

The open questions are what those new logistics will be, whether resources can become loose materials, and how much building freedom caves can offer without losing their cave feel. For players, the practical meaning is that a mature surface factory may still support the expansion, but the cave will ask them to solve movement, visibility, and spatial constraints in ways that belts alone may not answer.
