About

RADIOSOL Guide is an independent, unofficial fan guide for the science-fiction exploration adventure RADIOSOL on Steam. The site collects practical Chapter 1 help in one place: the main route, radio puzzle settings, landmark navigation, Calypso 5 probes, achievements and completion checklists.

The guide is deliberately evidence-led. Route claims and numeric settings are checked against the sources listed on each page, and we prefer to mark uncertain details for review rather than invent endings, codes or statistics. Pages are revisited when official game updates or better research change the picture.

How we maintain content

• Launch, platform and update facts start from official Steam sources.
• Walkthrough details are cross-checked with dated public research and clearly labeled when they come from one source.
• Codes and ending details are not published until their official or documented status is clear.
• Every guide and data page records when it was checked or updated.
