Meduson is the third limited release volume in The Horus Heresy series of novels, released as a Horus Heresy Weekender Exclusive in hardback format. Meduson has yet to be re-released in non-limited format, although two of its short stories have been released as a stand alone e-book and audio drama.
Meduson was later released as Meduson: The Ultimate Edition, which contains the seven short stories from the original anthology, as well Grey Talon and The Either as full-cast audio dramas with complete production scripts. Also included is a brand new story, Hand Elect by Chris Wraight.
