The Hydrogen Line

Late October. Closed for the season.

You pull into a forest parking lot after dark with a dying engine, a weak torch, and a radio that keeps catching fragments of something half-buried in the static.

The Hydrogen Line is a short first-person horror game built around atmosphere, exploration, and radio-driven unease. Walk the lot, search the outbuildings, follow clues, and decide how long you want to keep listening when the signal starts sounding familiar.

What to expect
