The new Space Marine Codex makes every Marine hit harder while armies get smaller, so you’ll face fewer models, but they will be tougher and stronger now!
Of all the things GW could have changed on Marines, the humble boltgun getting buffed probably wasn’t high on anybody’s list. It’s been sitting at Strength 4 forever, and now it’s finally getting some teeth. Better yet, this change is in the new 11th Edition Space Marine codex itself, instead of showing up in a dataslate that could disappear again three months later.
The book itself is the flagship release for Warhammer 40k 11th Edition, following the template the Ork Codex set as the first 11th Edition drop. We already saw the kits and the book together in the first look, and plenty of what’s inside traces back to the Armageddon launch box.
Overall, they’re getting 230 pages, plus a pretty serious statline overhaul along with it. So if you’ve been watching the codex release schedule and wondering whether Marines were getting a proper book or another batch of faction pack PDFs, there’s an answer now.
Strength 5 Bolters Change Who Marines Are Allowed to Kill
- The take: Marines didn’t need a power bump, but GW gave them a pretty fundamental one instead of just fiddling with points.
- The evidence: boltguns move to Strength 5, Terminator plate moves to Toughness 5, Phobos units stay at Toughness 4 but jump to 8 inches of Movement, and the same treatment rolls out to every Astartes flavor in the game.
- If we’re right: points can make the army smaller, but they can’t put the wound roll back where it was.
One extra point of Strength doesn’t sound dramatic until you actually run the numbers. A Strength 4 boltgun wounds a T4 target on 4s and a T5 target on 5s. At Strength 5, those rolls become 3s and 4s. That works out to roughly a third more wounds from the same squad without adding another model or stacking on a stratagem.
That’s a lot more than a little cleanup around the edges. GW is finally making the bolter behave more like the weapon the lore has spent decades telling us it is.
Strength 5 Chainswords Break Everyone Else’s Wound Math
Now we get to the stuff Marine players are actually going to enjoy. Basic warriors move to Strength 5, and GW really does mean basic. Combat knives, chainswords, and bolt pistols all go up with them. Intercessor bolt rifles get two firing modes, one at Strength 5 and another at Strength 6, while Tacticus armor moves to Toughness 5.
So, now, that starts changing wound rolls all over the table. Guns that were comfortably wounding Marines on 3s need another look, because plenty of those matchups now push out to 4s. And unlike a Space Marine detachment bonus, you’re not building around this. These stronger profiles are now just part of the army.
Phobos Stays Squishy But Gets Eight Inches Of Movement
Not every Marine gets the same upgrade. Phobos armor stays at Toughness 4 while the Tacticus version increased, but Phobos picks up an 8-inch move instead. Their job looks pretty obvious now: get across the board, chase down isolated units, snag objectives, and don’t stand around trying to trade shots with the heavy stuff.
That fits in with how the 11th Edition rules have been pushing different units into clearer jobs. Phobos gets around the table while tougher Marines sit in the places where somebody actually has to survive getting shot. But, whether Phobos gets anything new out of the model refresh people keep rumoring is another question entirely.
Your 2,000 Points Buys Fewer Marines Now, and Every One Hurts More to Lose Now
So, those new stat buffs aren’t free. Points are increasing with profiles, and Marine armies are getting smaller as individual warriors get better. That’s been the fantasy around Space Marines forever anyway: fewer models that are better troops, with each one actually feeling like an elite soldier instead of another model you pull off the table by the handful.
We like that direction, and best of all, if you were planning to start Marines with the Armageddon box, you’ll need fewer models to fill out 2,000 points now!
The Buffs Don’t Stop at Codex Chapters
One of the best details came near the end of the video. GW is spreading the same stat changes across every Astartes and Heretic Astartes variant in the game instead of leaving half the power-armored factions stuck on older profiles.
Chaos Space Marines and Grey Knights were both called out. We’re talking Strength 5 storm bolters and Toughness 6 Terminators. Grey Knights only just got their 11th Edition detachments sorted, so now those changes are landing on top of a faction that was already moving. Anyone following the Grey Knights coverage knows they don’t exactly get free upgrades every day.
The Chapter supplements are also going away with the old codex. Blood Angels, Dark Angels, Space Wolves, and Black Templars are getting digital updates instead, including datasheets and new detachments, with no extra book purchase attached. We’re certainly not going to complain about free rules here.
It does leave four armies depending on digital updates instead of a book sitting on the shelf, though, and Chaos players who remember waiting on their own codex have already seen how that kind of setup can go over time.
Either way, those changes will hit Warhammer 40,000: The App automatically when the Space Marines codex launches in October.
Having those updates land in the app with the codex saves a lot of messing around, especially once multiple Marine books and Legends units are involved. GW used the same setup with the Orks codex rollout, and it looks like the rest of the codexes will follow the same schedule.
230 Pages Means GW Still Believes in the Book
Two hundred and thirty pages is a chunky codex for an edition where the actual rules can show up on your phone for free. A lot of that page count seems to go toward the setting instead. The lore section walks through a fortress monastery, from the Apothecarion where Marines are created to the Hall of the Fallen where the Dreadnoughts sleep.
That gives the physical codex more value now that codex pricing and book format keep shifting. If the rules are going digital anyway, the book has to offer more than an expensive stack of datasheets.
The rules side is also being handled sensibly, too. Everything updates automatically in the Warhammer 40,000 app when the codex arrives in October, following the setup GW explained in the 11th Edition Q&A on book changes and USRs. It also lines up with Wahapedia now carrying every 11th Edition rule in one place, too.
Final Thoughts on the New Space Marine Codex
Space Marines are already the most-played army in 40k, and now GW is making the models on the table better at the jobs they’re supposed to do. The Space Marines Codex release in October will show us how it all works together once the points are attached.
Those points costs overall will probably absorb part of the upgrade, and increase overall, as they should. They can reduce how many Marines you bring, but they can’t undo Strength 5 boltguns or tougher Terminators in the game now. Which is why the rest of the 11th Edition codex schedule may be more interesting than the Marine datasheets themselves.
The next few books should tell us whether GW is fixing Marines specifically or setting a new baseline for everybody else, too!
