The Planet Crafter – Magnetaris DLC set for December 8 release on Steam and GOG

Miju Games has announced the release date for The Planet Crafter – Magnetaris, a new DLC for the survival open-world terraforming game. Scheduled for December 8, 2026, the expansion introduces a hostile planet characterized by intense magnetic fields and severe storms.

While the DLC is developed for Windows, it will be accessible to Linux and Steam Deck users through the Proton compatibility layer. The expansion will be available on both Steam and GOG, offering new biomes, specialized magnetic technology, and expanded lore regarding the Sentinel Corp.

Technical availability and gameplay features

• Compatibility Layer: Linux and Steam Deck users will access the content via Proton, as native Linux support has not been confirmed.
• Multiplayer Model: The DLC features a specific cooperative structure where only one player in a group needs to own the Magnetaris expansion to allow up to ten friends to join, provided they own the base game.
• Progression Requirements: Accessing the new Magnetaris world requires players to have unlocked the interplanetary travel system in the base game.
• Content Expansion: The DLC introduces new machines designed to balance magnetic fields and new biomes to the existing terraforming loop.

Why it matters

For Steam Deck and Linux gamers, the reliance on Proton means performance will depend on the efficiency of the translation layer during high-intensity storm sequences. The expansion's availability on GOG also ensures that users utilizing manual Proton configurations for DRM-free titles can access the new content.
