Games Workshop just made 40k easier to play; the new faction packs collect every rule, errata, and FAQ in one handy download for each army.
Warhammer Community just made life a lot easier for Warhammer 40,000 players: they’re consolidating all the faction rules into downloadable packs.
Every army now gets its own all-in-one PDF loaded with the good stuff: extra detachments, Legends datasheets, errata, FAQs, and even those stray Kill Team units that never made it into the codex.
Here’s the latest on Warhammer 40k faction packs, the free rules you can download now!
40k Faction Packs: Everything in One Place

That last part’s key: no more guessing what got nerfed, tweaked, or quietly vanished overnight. At least we hope that’s how it will work; they haven’t actually rolled out any updates in these, yet.
Borrowed Brilliance from Age of Sigmar

It gives AoS some more intrinsic value for 40k; they can use it as the testing ground for 40k. And this isn’t the first time they have done this.
Rumor has it that the two design teams don’t always sync up or even talk at times, especially when it comes to ideas like how Chaos Daemons should function between systems, and who should get credit for them.
Legends, Kill Teams, and the “Forgotten” Units

One of the biggest perks of these Warhammer 40k faction packs is the inclusion of all those “in-between” units, the ones that slipped through the cracks between codex releases and Kill Team expansions. If you’ve got minis that haven’t seen rules love since 10th dropped, chances are they’ll find a home here.
That means your Legends units, Grotmas detachment options, and those extra datasheets that make narrative play fun again are no longer scattered across a half-dozen PDFs. They’re right where they should be: with the rest of your faction.
What’s Staying Separate (For Now)

Core rules updates, tournament companions, and Combat Patrol rules will remain in their own documents, too. That keeps things clean and avoids confusion for new players just learning the ropes.
40k Faction Packs: a Step Towards 11th Edition

And if the rumors are true that 11th won’t bring massive rule overhauls, this system could easily carry us through the next three to four years. You’ll get streamlined updates, fewer downloads, and a much cleaner way to track your faction’s evolution.
Final Thoughts on Warhammer Faction Packs
Credit where it’s due: the end result of these Warhammer 40k Faction packs here is good for everyone. Players get organization, clarity, and consistency; something the 40k rule ecosystem hasn’t exactly been famous for lately.
It’s a quality-of-life move that’s long overdue. Players have been juggling scattered PDFs for years just to keep their armies tournament-legal (or even play casual games).
So yeah, good move, GW. Keep this energy going into 11th edition. The players are finally getting something that feels like it was made with them in mind.
Download All the Warhammer 40k Faction Pack Rules!



There’s actually a major problem with the downloads that I’m not sure has been caught yet. Deathwatch Legends units have been removed from Agents of the Imperium packet. They get the pure Deathwatch list, but the Agents units (e.g. Kill Team Cassius – referenced in Deathwatch) are all missing. Probably an oversight, but a major issue for people (like me) using those elements as core for an Agents army. It also looks like the missing units from Legends (Thunderbolt Fighter and certain Death Korps and Grey Knights Land Raider Banisher) are still missing.
