New Iron Warriors are coming to 40k. GW teased hazard-striped parts, claws, and machine bits tied to the Eye of Terror. See what kits could be next.
Games Workshop just did that classic “blink, and you missed it” move in the New Year Preview, then followed it up with a proper tease. Bare metal. Yellow and black hazard stripes. Chunky industrial bits. And one set of shoulder pads that might as well scream “IV Legion” through a megaphone.
GW’s only hard confirmation so far is this: these teaser parts are tied to a new Warhammer 40k supplement called Eye of Terror, due out “in a few months.” But we all know what chaos legion these are for.
Let’s break down what GW showed, how it lines up with the Iron Warriors 40k rumors, and what you can actually do right now if you want to be ready when the siege doors finally open.
Updated on January 27th, 2026, by Rob Baer with the new reveals and solved teaser images.
GW’s teaser is basically a roadmap for Iron Warriors players.
- Bare metal with hazard stripes is the Iron Warriors’ visual identity. If you paint Chaos Space Marines and you’re tired of trim, congratulations, you have more to paint.
- The teaser images, as described, include a giant claw, a pintle-mounted flamer, a giant hammer, new Iron Warriors shoulder pads, an industrial exhaust-looking piece, and a massive armored foot that looks like it belongs to something big.
GW is being coy, but the parts tell a story, and not a subtle one. A “reinforced bulkheads and daemon-forged hydraulics” story.
Why This Feels Like More Than “Just an Upgrade Sprue”
Iron Warriors rumors have been doing the rounds for ages, but these line up with a pattern GW loves right now: tease a vibe, drop a supplement, then roll out kits that support that narrative.
The key rumor beats have been consistent:
- New Defiler kit (or at least a refreshed daemon engine kit that can flex across Chaos Space Marines)
- New Mutilators (or some kind of brutal, close-range elite refresh)
- Expanded Chaos Space Marines support that finally gives Iron Warriors a real push in 40k
- An Iron Warriors upgrade kit, possibly tied to a future Combat Patrol
The shoulder pads are the easiest “yes” in the whole pile. But the claws, exhaust, and big stomp foot are the kind of parts you do not bother teasing if the payoff is only a couple of helmets and a transfer sheet.
Let’s talk through the most likely homes for these teaser bits.
A giant claw mounted near a marine shoulder: Solved
This has been revealed on the new Warsmith mini! He’s taking up a lot of the pics all on his own, but not everything.
Pintle-mounted flamer: Solved
Another bit solved. Same thing here as the claw, it looks like the Warsmith is going to take center stage in the Iron Warriors update.
Giant hammer: Solved
A hammer says, “brutal melee,” but luckily, this has been solved and will be a part of the new upgrade sprue. Need your champions to smash the enemy? This is your answer.
New Iron Warriors shoulder pads: Solved
This one is the cleanest read: sprue support is coming. Just like the hammer above, this has been revealed by GW to be part of the new upgrade sprue.
Exhaust system for a big machine
That is almost never a Marine-sized part. That is “daemon engine” or “walker” territory. It also fits the Iron Warriors identity like a glove, because nothing says IV Legion like industrial pipes and a war crime factory aesthetic.
Claw on the ground, lines up with daemon engine rumors
This is where the Defiler talk starts feeling less like cope. A new Defiler kit, or a new daemon engine kit that can build multiple variants, would make perfect sense for an Eye of Terror-themed Chaos Space Marines supplement.
A claw that looks like it fits a big model
Chaos has a lot of “dreadnought-adjacent” space. This could mean:
- A new kit.
- A refresh of an older kit.
- A new option sprue.
- Mutilators are front and center of the new stuff
Whatever it is, it reads like “arm that rips doors off tanks,” which is a very Iron Warriors sentence.
A giant foot, suggesting large infantry
That could be:
- A big character.
- A heavy elite.
- A daemon-forged brute unit.
- Perturabo… maybe?
It also raises the question: if we get new Mutilators, do they come back as a bigger, modern plastic kit with real presence on the tabletop? That foot tease feels like the scale is going up.
The Iron Warriors Combat Patrol Rumor: Solid Core, Questionable Hype Ceiling
The rumored Iron Warriors Combat Patrol loadout is straightforward and playable:
- Warpsmith
- Ten Legionaries
- Five Havocs
- Five Chaos Terminators
- Iron Warriors upgrade sprue
If that is real, it is a strong starting block for a 40k Iron Warriors force. You have:
- A tech-flavored HQ that actually makes sense for daemon engines.
- Bodies that score and trade.
- Havocs that bring the siege-gun energy.
- Terminators that do the “walk through fire, hold the point” thing.
The only catch is the hype factor. If the “new” piece is mostly an upgrade sprue, Iron Warriors players who want a big marquee moment will call it a nice box, then keep waiting.
That is why the teaser claws and big-machine parts matter. They hint that this is not just a branding pass.
Defiler and Mutilators: The Rumors That Keep Refusing to Die
A new Defiler kit
The Defiler rumor makes sense for two reasons:
- It is iconic, but the kit is old enough that a modern refresh would be welcomed.
- Daemon engines are having a moment, and Vashtorr hovering in the background of the Chaos narrative direction makes this feel less random.
A multi-option daemon engine kit that can be built in different ways is exactly the kind of “use it across multiple Chaos Space Marines builds” product GW loves.
Mutilators returning
Mutilators are the kind of unit that feels like it should exist in plastic, on a modern scale, with rules that do not leave them stranded in the attic.
If GW is leaning into “brutal close-range chaos,” then a reimagined Mutilator-style kit could fit that big-foot tease perfectly.
Is Perturabo Returning in 40k, or Is This a Different Kind of Return?
Let’s talk like grown hobbyists for a second.
A Chaos Primarch return is always plausible. Timing is the whole game. The other possibility is spicy in a different way: the rumor could be a case of crossed wires between 40k and Horus Heresy, meaning people saw “new Perturabo” and assumed it was a 40k return when it might be a Heresy-era sculpt instead.
Either way, the smart play is to treat Perturabo talk as the long game. The short game is Iron Warriors getting real support and real kits.
40k Iron Warriors: What to Watch For Next
Between the Grotmas prophecy chatter and GW openly tying these bits to an upcoming Eye of Terror Warhammer 40k supplement, this feels like the start of a broader Chaos Space Marines push. Iron Warriors are an easy win here because they already have a strong identity, and the range has obvious gaps that a refresh could fill.
So no, we are not locking in “Perturabo confirmed.” But yes, the IV Legion is getting attention, and it is finally looking like more than just a paint scheme and a dream.
If you want to play it perfectly: build your core, keep your options open, and watch for the moment GW shows the full model silhouette. That is when the real shopping list writes itself.

What new units do you think GW will drop for the Iron Warriors?
I have to agree, my first thoughts were that all the images come from a new warsmith. Even the exhausts fit E.g. the warpsmith, especially with the heavy duty feet to take the weight.
Those exhaust pipes are defo not from a warsmith/warpsmith, Those are most definitely from the new rumored defiler kit,
That ain’t a pintle mounted flamer, not sure how you are viewing that image, but you can clearly see its a servo arm mounted with a flamer, you can just see the ball joint, as seen on tech marines for example, and just below that, is what is clearly a shoulder plate, which from the look of how its angled, its Cataphractii, which likely means a plastic Chaos Cataphractii warsmith, at minimum, or if we are been optimistic a named character
