Don’t miss this! The Warhammer 40k 10th Edition core rules book from Leviathan has been leaked with over 60 pages on how the game will play!
With the new edition dropping in June, it was only a matter of time before we saw some leaks hit the internet. It’s always nice to get a sneak peek into the rules, and these look like they are taken from the book, but with any leaks, nothing is 100% until GW reveals it.
Warhammer 40k 10th Edition Year One Codex Rulebook Roadmap
You won’t even have to wait for your Codex to start playing! Every single faction is getting a complete set of Index Cards with datacards for each unit that’s currently available, as well as their own Detachment rules, Stratagems, and Enhancements. These will be available to download online for free from day one, while they’ll also become available in the app. You’ll be able to buy inexpensive physical copies at the same time.
They also mentioned in the live stream that the factions in the 10th Edition Codex roadmap would each have a new model released with their rules as well!
It’s great to see GW make some promises about so many factions within the next year, and with a good variety covered, many players should be happy!
Perhaps better yet, all 28 Warhammer 40k Factions will get a set of Datacards available for free download and on store shelves for purchase that will feature the rules to start playing your armies in the new edition!

If you’re looking for a chart of the USR rules, a “printer-friendly” version is also posted here. Here are all the latest rules previews that no one had seen from the full 10th Edition 40k Leviathan Core Rules Book.
10th Edition 40k core Rules: Core Concepts


Coherency & Engagement Range

Then, if you’re a unit of seven models or over, you have to be within the coherency of at least two models. If your turn ends and you’re not in coherency, you must remove models until the unit is coherent.
Having to be within two models will probably stop the insane conga lining we have seen in the past.

10th Edition 40k Core Rules: Muster Your Army & Missions


You can also include more than one Epic Hero, just not more than one of each. Lastly, you pick who your Warlord is.
10th Edition Warhammer 40k Missions

Some of the significant differences we noticed from 9th Edition are after determining the attacker and defender, you must then decide which units your characters are going into, which units will be embarked in transports, and which models will be in strategic reserves (before any deployment has happened).
After that, the next main difference is whoever takes the first turn moves their Scouts first, and you roll off for infiltrating units.
Objective markers are very different now as you cannot be on top of them (i.e., ending your move on top of them.) However, you can control them within 3″, and they recommend using a 40mm base (or something about that size.)
Now that we have new OC rules keep in mind that if you have a higher combined OC, you control the objective.

Secondaries can also be random or fixed, and each player can decide which they will go with. Lastly, placing objective markers still goes from one person to the next with similar rules for where they can be placed.


These New 10th Edition 40k Terrain Features & Cover Rules Are Clutch Now
Now if you are in cover, you can only get +1 to your save; however, if you have a 3+ save, you cannot improve it to 2+ against 0 AP attacks.
This is interesting as you can move over terrain as if it were not there. However, for anything over 2″, you must use movement to go up it. It also seems like most terrain does not impede movement.




The big difference here, and something that might force you to remodel some terrain, is you cannot have your base hanging off the end, meaning you have to be entirely on the higher levels.
10th Edition 40k Core Rules: Transports & Aircraft
The new Warhammer 40k 10th Edition rules were spotted over on Imgur, but we also have them all here.

You can embark on a transport whether you are moving, advancing, or falling back, but the whole unit has to be within 3″ of the vehicle. For disembarking, you can either get out before the vehicle moves to charge, or you can get out after the transport moves, but you cannot charge.
Lastly, you cannot disembark if the vehicle advanced or fell back, and you cannot disembark if you cannot fit all models with 3″ as well.

However, while you don’t take as many auto-deaths, you will be battle-shocked until the start of the next command phase. Lastly, the unit cannot declare a charge if you somehow get your tank destroyed in your movement phase.

New 10th Edition Core Rules: Aircraft

Aircraft can move any amount of distance now and must make a minimum move of 20″ (but cannot advance, fall back, or charge), so fly them wherever you want! However, you do have to make a straight line move and can rotate 90″ at the end.
You can also hover your models, which means they don’t have those other aircraft rules but can start the battle on the board. But you have to declare this at the beginning of the game.

They also don’t count as being the closest model for other units.
