Do No Harm

Do No Harm is a 19th-century doctor simulator with a Lovecraftian story. You play a village doctor, diagnosing and treating patients with ancient, often cryptic medical procedures while trying to survive 30 days in an increasingly hostile environment. The story follows a proxy war between Azathoth and Cthulhu over the island village, and through it, the world and humanity.

Diagnose and treat patients

You assess patients’ symptoms, use tools to narrow down possible treatments and inject them with medicine. You can consult the Book of Medicine, a grimoire-like guide, and experiment with remedies inspired by Early Modern medicine. Treatments may work or bring consequences.

Face the horrors

Nightmarish entities warp reality as you work. They can cause hallucinations, prevent you from interacting with items and deceive you about treatment results. Anomalies also intrude on your daily medical practice and affect your Sanity.

Choices and endings

Your diagnoses, treatments and moral decisions affect the outcome, with 12 endings to find. Your reputation also shapes how the villagers act around you. Your choices determine whether you save the villagers, descend into madness or uncover the truth behind the horrors.
