Maybe the biggest news is that without all the Space Marine supplements, there are only around 25 factions of armies in Warhammer 40k total. It is kind of wild to think that by 18 months into 10th Edition, 14 of the Codex books will have been released! Thats over half of the ones that match existing factions.

Warhammer 40k 10th Edition Codex Book Lineup & Release Dates:

The release dates roadmap schedule for all the Warhammer 40k 10th Edition Codexes is like a gift that keeps on giving. While dates can sometimes shift, Games Workshop has provided a flexible timeline to help you plan your next big army overhaul. Here are the key release dates to mark on your calendar for new 10th Edition Warhammer 40k codex books:

The Aeldari, Astra Militarum, and Imperial Knights are gearing up for fresh codex releases in early 2025, and let’s just say—things are about to get wild on the battlefield. Well, maybe? *Technically, this is what they did say about the new Aeldari and Imperial Knights, which may not mean codex books perce. However, we assume most hobbyists are expecting them, as the Nova Open teasers were a bit light on content…

*Krieg’s finest aren’t the only ones to receive new aspects of their army in plastic, and so the next faction to swoop into stores will be the Aeldari. And with so many Xenos threatening the Imperium, it’s only right that the noble Imperial Knights will be striding out to meet them on the field of battle soon afterwards.

Plus, Games Workshop hinted that a Chaos faction might be crashing the codex party as well! The question now may be how long it will take for GW to release the rest of the codex books after early 2025, as they tend to reboot 40k every three years. Based on that trend, the 11th edition Warhammer 40k is on track for a summer 2026 release!

Which 10th Edition 40k Codexes are Coming Next?

Codex Imperial Agents was released in August of 2024, and no one suspected Games Workshop to reveal the new 40k Codex Imperial Agents rules, character models, and three new battleforces all at once.  Plus, they said the Grey Knights codex would be released in 2025. Be sure to get the full story on the new Imperial Agents codex and products here.

Blood Angels Codex

The Blood Angels will also have a codex book released on September 7th, 2024, in their new Army Box Set, which will be followed up by the general release supplement book similar to the Dark Angels release before the end of the year.

Headed into 2025, one thing’s clear: 40k is about to get a whole lot more chaotic—and we’re not just talking about those Chaos rumors. Whether you’re rooting for the noble (if slightly unhinged) Astra Militarum, the stylish yet deadly Aeldari, or the towering Imperial Knights with their love of giant weapons, there’s plenty of excitement on the horizon.

Upcoming & Unreleased 10th Edition Warhammer 40k Codex Book Release Dates

Here’s the scoop on which factions still need their codex books compared to the last edition, along with what’s coming up next.

Chaos: Emperor’s Children Codex

You can bet your dice that the Emperor’s Children Chaos Space Marines are definitely getting their own codex and models soon. They got kicked out of the latest Chaos Space Marines codex and put into an Index, so it’s pretty much guaranteed they’re next in line for their own standalone faction.

So get ready to make some noise soon!

What are Warhammer 40k Codexes?

Warhammer 40k Codexes are essential guidebooks for players to play the different factions in Warhammer. They serve as rulebooks and lore compendiums for all the playable factions within the universe. When combined with the core rules, they have all the rules you need to play your army.

Each Codex delves into the history, tactics, and unique characteristics of a particular army, offering players insight into the strengths and weaknesses of their chosen faction. From the stoic Space Marines to the insidious forces of Chaos, every Codex provides detailed information on unit types, special abilities, and army-building strategies.

For example, the Necrons Codex introduced new protocols that offer dynamic battlefield strategies, while the Orks Codex doubled down on the chaotic and unpredictable nature of their warfare. These key changes highlight each faction’s unique characteristics, ensuring every game feels fresh and exciting.

These books not only lay out the rules for gameplay but also suck you into the awesome narrative and worldbuilding of Warhammer 40k. They’re packed with captivating stories, stunning artwork, and detailed illustrations, bringing the grim darkness of the far future to vibrant life.

GW keeps these codexes up to date to keep the game balanced, with new editions introducing revised rules and extra content. Can’t have players feeling left out in the cold, can they? Generally, these updates are done through FAQs, Balance Dataslates, and points changes.

What Will Happen To Codex Books In 10th Edition Warhammer 40k?

GW’s First 10th Edition Codex Roadmap

The Design Studio has taken a long, hard look at the state of the game. The core rules that underpin Warhammer 40,000 are strong, but in their review, they found many opportunities for streamlining the system, fixing rules that didn’t quite sit right, and numerous other ‘quality-of-life’ changes. 

As they said multiple times, the new edition aims to simplify and streamline a lot of the clutter surrounding rules. With this reveal, they reiterated that idea further.

Those sticky complexities have now been smoothed out, and without losing any of the game’s depth. These much-needed simplifications are substantial enough that, from a rules perspective at least, every ninth edition codex has been rendered obsolete. That’s not to say they’re useless – they’re still bursting with the lore, history, and short stories that define each faction, and until new codexes emerge over the course of the new edition, these books will still be the main repository of the knowledge you need.

While it sounds rough, “rendered obsolete,” it does make sense. The overhaul they are talking about seems to be all-encompassing, and trying to tie in or errata all the current rules just isn’t worth it and would be confusing for players anyway.

The associated packs of datacards are also obsolete. One of the main vectors for streamlining armies has been to heavily reduce the numbers of Stratagems available to each faction. Gone are the days of shuffling through 50 cards to find the right ability – each army now has a lean list of them included on the double-page spread that defines them.

With the band-aid ripped off, datacards containing the rules from the codexes will also be unusable.

You will nevertheless be able to play your chosen army as soon as the new edition lands. We are releasing revamped, restatted, and reconsidered datasheets for every single unit in the game – all free to download at launch and ready to go. You’ll also be able to buy inexpensive packs of these cards at launch.

However, to ease the pain a bit, all factions received a free online Index set of rules on day 1!

Boarding Actions, on the other hand, are still going strong. The core rules in Arks of Omen: Abaddon were specifically written to work with the new edition, and the book will remain available for the foreseeable future. All you need to play this tight and tense format of Warhammer 40,000, is this book, the book that contains your own faction rules, and a set of terrain.

The last tidbit they gave us was regarding the Arks of Omen series, and thankfully, these recent books and their rules were made to continue working into the 10th edition.

Impact on Warhammer 40k Gameplay and Meta

Buckle up because, between the new 10th Edition Codexes, quarterly points changes, and the Balance Dataslate, the is set to turn the gameplay and competitive meta on its head. With new units, rules, and mechanics, get ready for some serious strategic shake-ups.

Influence on Gameplay

The new Codexes are designed to keep things fresh and exciting on the battlefield. Each Codex introduces unique units and abilities that reflect the distinct flavors of their factions. For instance, the Space Marines Codex emphasizes versatility and tactical flexibility, allowing you to adapt your strategies on the fly.

On the other hand, the Tyranids Codex focuses on overwhelming your foes with bio-engineered monstrosities, leveraging sheer numbers and terrifying adaptability to dominate the battlefield.

These new gameplay elements encourage players to experiment with different strategies and army compositions, making each game of Warhammer 40K more dynamic and unpredictable. The updated rules and mechanics ensure that battles remain balanced and engaging, with each faction having its own strengths and weaknesses that need to be managed cleverly.

Shifts in the Meta and Competitive Scene

Newly released Codexes have definitely shake up the competitive meta. As players integrate these fresh units and rules into their armies, the balance of power will shift, leading to new strategies and counter-strategies. Competitive players will need to stay sharp, continuously adapting their tactics to counter the latest threats and seize new opportunities.

For example, the Necrons’ new rules forced other factions to come up with new tactics to counter their relentless resilience and advanced tech. Meanwhile, the Orks’ new units introduced a level of chaos that even the more versed players found challenging to predict and counter, while the Adeptus Custodes book tumbled out of the gate at launch.

These shifts in the meta will keep the competitive scene vibrant and exciting as players explore new ways to outmaneuver their opponents and claim victory. The evolving strategic landscape will also provide plenty of opportunities for casual and competitive players to experiment with different army builds and tactics, making every game a new adventure.

How Do You Redeem Warhammer 40k Codex Codes?

On the back page of every codex, there is a code that will grant you online access to the rules and the army builder function within the Warhammer 40k app. You will need to have a My Warhammer account to redeem the code. Once you have that setup, you can go into the Warhammer 40k app and type in the code that comes on the back page of the codex.

Once you have entered the code, you will then be able to access the rules within the 40k App, which will be automatically updated when GW updates the rules, and you can also use the army builder in the app to make your army lists. The code can only be used once, so don’t share it!

Ease of 10th Edition 40k Codex Release Dates

With a complete framework for every faction, making new codexes has never been easier for GW. All they have to do is look at the meta, change some points, fill in some new detachments, and add artwork. Boom, a new book!

For the last edition, they had to make basically entirely new books with only the models laid out for them. This time, they don’t have to worry about individual points, coming up with the identity for the edition, or anything like that.

So, in theory, it should be easy (as long as they can ship out the products) to make new books, stay on track, and actually make changes closer to release than usual.

Final Thoughts on the Warhammer 40k 10th Edition Codex Releases Dates & Roadmap

With the release of 17 new Codex books by Spring of 2025, players have a lot to look forward to.
