Marneus Calgar, Cato Sicarius, and the Victrix Honour Guard return with “casual” new 40k Ultramarines codex rules and new models!
A new dawn rises over Ultramar, and it’s looking pretty heroic. Marneus Calgar, Cato Sicarius, and the brand-new Victrix Honour Guard kits are up for pre-order, and people are itching to throw the models on the table.
Instead of making everyone wait until release day, Games Workshop dropped a preview (legal for casual games) of their new 40k rules, and there’s a lot here for Ultramarines codex fans to get excited about.
Marneus Calgar Rules Level Up
Updated on October 24th, 2025, by Rob Baer with the latest rules.

But bigger, he can act normally after falling back or advancing, so throw him into the fray and move wherever you need.

Worth mentioning: this isn’t a replacement for his Gravis armor version. You can run either one, just not both in the same army.
Cato Sicarius 40k Ultramarines Rules

He’s also rocking a brand-new ability to replace Lead From the Front and can now hang out with the Victrix Honour Guard, even if Calgar is already tagging along. The boys in blue clearly know how to coordinate with these new Ultramarines rules.
Victrix Honour Guard Rules are Tough and Loyal

So, not only are they hard to kill, but every casualty just makes them angrier.
They’ve got Objective Control 2, meaning they can muscle other elite units off points with ease. You can field them in squads of three or six, and while the datasheet technically allows for one, the points cost makes it clear that three’s the minimum (or at least that’s what the article says; the points will drop soon).

The Champion hits like a truck with Precision and Twin-linked on his blades of honor, while the Ancient’s banner gives the unit a once-per-game combat boost. Stack those buffs, and your opponents are going to feel it.
New Ultramarines Codex Rules Drop Timing Makes Total Sense

It’s nice to see GW’s studio, events, and rules teams actually coordinating for once. No mixed messages, no “maybe legal” debates, just clean timing that keeps everyone on the same page.

Final Thoughts on New Ultramarines Codex Rules
Between Calgar’s redeployment flexibility, Sicarius’ new dueling tricks, and the Honour Guard’s mix of durability and aggression, Ultramarines Codex rules are giving players some real depth back into their lists.
Plus, maybe best of all, when the pre-orders arrive, you can start playing right off the bat.
