The catalogue lists The Horus Heresy: Book Four – Conquest as an expansion for Warhammer 40,000 (Seventh Edition). Expansions add new content, rules or scenarios to the base game and usually cannot be played on their own, so you need Warhammer 40,000 (Seventh Edition) to use it. Check that your edition of Warhammer 40,000 (Seventh Edition) is compatible, as some expansions were revised between editions.
