Here are all the new 9th Edition 40k Space Marines codex content and rules that we know right now, as new previews are on the way.
If you haven’t been following along, we just saw GW announce that a new preview is coming this Saturday and they’ll be expanding on the details of the Necron and Space Marine codex as well as previewing a few more models. Well, the Necron codex lies largely a mystery but we’ve seen a decent bit of info here and there for Space Marines. Here’s everything we know that’s coming.
Space Marine Codex Previews Coming Saturday


All The New 9th Space Marines Codex Rules We Already Know
This YouTube video from WarhammerTV is where the community has pretty much gotten all of their info on the coming codex.
Codex: Necrons and Codex: Space Marines combine the codex content you love with all sorts of new stuff for the latest edition of Warhammer 40,000. Sumptuous art and thrilling lore bring each faction to life, while the layout of each book has been redesigned in order to be accessible and easily referenced.
Within the previews, we’ve seen a layout of all the main Space Marine Chapters and their Chapter Tactics. The page is really blurred but we’ve laid out the rules as best as possible below.

- Dark Angels: 1) +1 to hit if the unit did not move in this turn and 2) something about Combat Attrition, probably auto-pass.
- White Scars: 1) can Charge after Advance or Fall Back and 2) can fire Assault with no penalty after an Advance move.
- Space Wolves: 1) +1 to hit in melee if the unit charged, was charged or heroically intervened and 2) units with this tactic can heroically intervene as if they were characters.
- Imperial Fists: 1) ignore Light Cover and 2) 2 (probably only 1, blame the wonky screenshot) additional hits with unmodified 6s with bolt weapons.
- Crimson Fists: 1) +1 to hit when the target unit contains 5+ more models than this unit (VEHICLE counts as 5) and 2) 1 additional hit with unmodified 6s with bolt weapons.
- Black Templars: 1) reroll Advance and Charge rolls and 2) 5+ feel no pain against mortal wounds.
- Blood Angels: 1) +1 to wound when charging, charged or heroically intervening and 2) +1″ to Advance and Charge rolls.
- Flesh Tearers: 1) +1 to wound when charging, charged or heroically intervening and 2) -1 AP on unmodified wound rolls of 6.
- Iron Hands: 1) 6+ feel no pain and 2) double wounds on the damage chart.
- Ultramarines: 1) +1 Leadership and 2) can shoot in a turn during which it Falls Back, but at -1 to hit.
- Salamanders:1) you can reroll one wound roll when resolving that unit’s attack and 2) each time an attack with an AP characteristic of -1 is allocated…treat it as 0 instead.
- Raven Guard: 1) count as being in Light Cover if the attacker is more than 18″ away and 2) INFANTRY only count as being in Dense Cover if the attacker is more than 12″ away.
- Deathwatch: 1) each time a model with this tactic makes a melee attack against TYRANID, AELDARI, ORK, NECRONS or TAU, reroll a hit roll of 1 and 2) after both sides have finished deploying their armies, select one battlefield role. Until the end of the battle, each time a model with this tactic makes an attack against an enemy unit with that battlefield role, reroll a wound roll of 1.

That makes the Heavy Intercessor, the Captain with Heavy Bolt Rifle, and both Primaris Land Speeder units as prime candidates for what will be revealed. We’re only a month away from the codex releasing after all and they have to give the community some time to drool over the new minis.
(includes the Primaris Lietantant or Necron Overlord)
