Harry Potter & the Codex of Corruption is an adult parody adventure built in HTML by The Merry Mage. The player takes the role of Harry Potter after acquiring a forbidden manual of dark sex magic. Starting with simple tricks like seeing through clothing, the spells grow progressively more twisted as Harry uses them to compel female classmates to satisfy his urges. The game warns that reckless use can lead to death, expulsion, or being consumed by darkness, and offers multiple endings based on the choices made. The presentation uses 3D computer graphics with animation, leaning into themes of corruption, fantasy, and mind control.
The current build is Chapter 10, originally released on November 6, 2022, with the most recent update dated March 16, 2024. Development is still in progress, as only one route of Chapter 10 is complete and further updates are expected. The game runs on Windows in English and is uncensored. All artwork is original, and the characters are stated to be 18 or older. Upcoming content teased in the changelog includes more extreme scenarios involving Hermione, Ginny, and Luna.
