RADIOSOL September 2026 Recap: Launch & Chapter 1

RADIOSOL launched on Steam on September 30, 2026. The release arrived with Chapter 1 rather than a complete multi-chapter campaign, and later chapters are described as planned updates to the base game instead of paid DLC.

The checked store listing identifies TripletConcept, Yodez, Hius and WhereaboutsUnknown as developers, with TripletConcept as publisher. The game is categorized as Adventure, Indie and Simulation, and it is a single-player title.

Launch facts

RADIOSOL supports Windows and Linux through Steam. The listed Steam App ID is 2934330. A Mac version is not listed in the checked store data.

The game puts players in control of a many-limbed machine exploring abandoned cities and enormous artificial structures after a planetary catastrophe. Direct sunlight is lethal, so route planning and shade are central to traversal.

Radio signals also play a functional role. They connect story prompts, downloadable files and Chapter 1 puzzle objectives rather than acting only as background sound.

What was not claimed at launch

This recap does not add an ending count, final ending names or a complete frequency table. Those details were not confirmed by the material checked for the launch-period research.

No active code system was verified either. The RADIOSOL Codes page therefore lists “none confirmed” instead of using placeholder rewards or invented redemption steps.

Controller support and an official Steam Deck rating were not listed in the checked store data. Those remain “to be confirmed” until official information says otherwise.

Where to start

New players should begin with the RADIOSOL Beginner Guide. It explains the controls, systems menu, sunlight rules and early route toward Megapol.

Players who already know the basics can use the RADIOSOL Walkthrough for the main route. For a broader review of landmark order, the RADIOSOL Map Guide collects the researched navigation anchors.
