Editing Horus Heresy (section)

===Second Edition===
The first two books for the new edition of the tabletop were revealed at Warhammer Fest 2022: the '''Liber Astartes''' and the '''Liber Hereticus'''. These are basically updated and combined versions of the LACAL and ICL books. Both books contain the rules for all non-Legion-specific units, while the Liber Astartes has the rules for the loyalist legions and the Liber Hereticus has the rules for the traitor legions, including their Primarchs, unique units and wargear, Rites of War, Warlord Traits, and faction abilities. The '''Legacies of the Age of Darkness''' PDF contains the rules for vehicles, units, and characters who either never had models or whose models are now out of production, including most of the Legion-specific special characters, Castraferrum Dreadnoughts, the [[Crassus Armored Assault Transport|CRASSUS ARMOURED ASSAULT TRANSPORT]], and all of the Baneblade variants. Later leaks, which Warhammer Community would confirm, revealed that there would also be books for the Mechanicum ('''Liber Mechanicum''') that would contain rules for the Taghmata, Knights and Titans as well as a book for the Custodes, Sisters of Silence, Solar Auxilia, and Divisio Assassinorum ('''Liber Imperium'''). Daemons of the Ruinstorm and Imperialis Militia/Warp Cults will get downloadable Legacies lists, and according to the Legacies PDF the Knights-Errant and Blackshields are being made into full factions. They will also continue to release the Exemplary Battles series; the previously released PDFs got a separate update PDF in order to work with the new edition.

The core rules have been drastically modified with the addition of "Reactions", which make gameplay more dynamic. In addition to basic reactions such as Overwatch that can be taken in response to the opponent's actions, each Legion now has an "Advanced Reaction" that is more powerful but requires more specific conditions to work. Furthermore, USRs have been rewritten to be more granular (e.g. Bulky, Very Bulky, and Extremely Bulky are now Bulky (X), where X is is how many models that unit counts as for the purposes of transport capacity) and the Psychic Phase has been removed in lieu of the pre-7th edition manner of resolving psychic powers.

Warhammer Fest 2023 saw the series finally get back to campaigns after getting most of the armies out of the way, with the first being '''Siege of [[Cthonia]]''' and the war the Sons of Horus and Imperial Fists had there.
