Goonhammer Reviews: Horus Heresy Third Edition (Updated August 6, 2025)

The day is finally here! Almost a dozen writers and editors have spent the last however many weeks (we've lost track) preparing for the launch of the third edition of Horus Heresy, the fiddly, finicky, standoffish cousin of friendlier, more predictable Warhammer 40000 -- and we wouldn't have it any other way. Whether you're new to the game, coming over from 40K, or returning after a long absence, we've got coverage of all the edition launch materials, what they look like, and how to use 'em.
