The first paid add-on for Satisfactory brings new underground biomes, buildings, creatures and a new story.
On 29 September 2026, Coffee Stain Studios announced the first paid expansion for Satisfactory: Core Values. As the name hints, this time the factory grows deeper rather than wider β Pioneers will build beneath the surface as well.
- New underground biomes: a brand-new expedition below the surface, with new resources, flora and fauna.
- New factory buildings and production lines: fresh building options for your underground factory.
- New creatures: including a feline-like companion.
- New story: a storyline of its own centered on the underground.
- Scope: reportedly around 400 to 500 hours of additional content.
- Platforms: PC (Steam, Epic Games Store), PlayStation 5 and Xbox Series X|S.
There is no release date yet. According to reports, the expansion will not launch in 2026. Coffee Stain has not revealed a price either.
Many details are still unclear β for example how the underground connects to existing saves and how co-op factories will work down there. We are following the announcements and will update this post as soon as there is news.
An expansion is the perfect excuse to start a fresh factory with friends. With your own Satisfactory server from ZAP-Hosting, your factory keeps running around the clock β even when nobody is online. Everything is configured conveniently in the web interface, including DDoS protection and SSD performance.
