40k 40k Perturabo + Stand-Alone Iron Warriors Codex (RUMOUR)

I really wish GW would actually finish one of the not-DG Cult Legions that they've already spun off instead of spinning off another doomed to be unfinished Chaos faction. They can even finish Thousand Sons. I don't play TS, and they are probably my least liked Traitor Legion overall, but they were spun off first, and could really use some more love. Similarly, Emperor's Children have a comically low number of datasheets, and need something to fill for their lack of Predators, Forgefiends, and Helbrutes. Maybe a nice big corrupted Leviathan dread with sonic cannons and a big doom siren to fill in their lack of ranged vehicle options?

 

Iron Warriors are represented just fine by the CSM book. Disolords, Warpsmiths, Oblits, one can build a very flavorful IW army as-is.

Slight counterpoint; by parsing out legions as their own thing they can allot more release slots to the overall chaos faction per edition. So instead of one release slot for just CSM (plus maybe something for end of edition) they now have 5 release slots per edition for spiky power armour.

Splinter factions losing access to cultists, vehicles, and monsters they all should have access to can be entirely pinned on the rules team, who feel like a bunch of chucklenuts at times.

Counter-counterpoint:  This ends up amounting to one new character model per spinoff, per edition. The only actual new squad/vehicle that has been added post-launch for any Cult Legion has been the Egyptobots for Thousand Sons, as far as I am aware. That's not so bad for DG, as they already have two unique terminator variants, multiple unique demon engines, and otherwise feel like a complete and unique army, but it's a real issue for the other three Cults. Blame whomever you wish, but GW needs to fill in the existing Cult armies before spinning off another Chaos faction to be dripfed one character per edition.

World Eaters also got Goremongers via Kill Team, so releases for the cult legions don't need to strictly tied to codex releases.

Imo the alternative then could have been all legions just having the regular lord and jump lord release this edition, though how any freed up resources would have been reallocated is anyone's guess. In essence I do want them to still have access to the CSM stuff, but at least the 4 cult legions kinda also need their own space. It should just be in addition to all the basic stuff. And out of all of GWs little competing subdivisions I guess we can just as well point to the number crunching pencil pushers who need their strict sales allotment numbers, who probably get conniptions when they can't tell which of the 10 or so factions bought which rhino kit.

True, though it doesn't quite match the "one unit for each faction each edition" cadence of 40k, and feels more like random bonus allotment depending on what theme GW wants to go. Maybe they roll dice and Imperial Agents simply gets luckiest. What with their 4 kits in the current rotation?

[jimbo1701]

I have always wanted GW to revisit the notion from (IIRC) 7th edition where there is one core book for each chaos and loyalist marines, and then one supplement book for each of them, let’s call them space marine chapters and chaos legions.
 

The supplement book would be comparable in size to the parent book and contain all the datasheets / faction rules and 1-2 detachments for each of the individual legions. Crucially, it would also contain a matrix table for both datasheets and detachments (so if you play black templars for example, you can’t take say scouts / librarians from the core book nor gladius detachment) 

Would mean less release windows though so I doubt he will ever entertain the notion. 

I also feel that eldar should be broken up in a similar way - asuryani for the craft world and aeldari for all the other factions.

Depending on structure you also run the risk of all the supplements being simply better than the base book due to having more focused or expanded options in a particular direction. I can't see what advantage there might be to someone running from the base book at that point, so much so, that it's questionable sales practice really.

It wouldn’t be much different from now in that regard, as competitive players tend to pick and choose the best detachments for the army regardless of chapter. My suggestion would be to limit / remove certain detachments and datasheets from the core book to attempt to redress that balance, certainly for the more divergent chapters that tend to have access to more datasheets and detachments than the codex equivalent.
 

It would be, as it is now, a core book of common units and a second optional book of unique units. Newbie players who only want to collect space marines would need just the one book, players who want to play divergent chapters would need two as they do now. It would be 2 release waves rather than the 5+ it is currently. 
 

Using black Templars as an example again, you could remove the gladius / stealth detachment options yet retain the others and add in 2-3 unique datasheets. Equally, you could remove datasheets as they have already in their codex that are either unsuitable for that chapter (librarians and scouts come to mind) or have an equivalent unique unit for that chapter.

I'd be most concerned with ending up in the same situation as 9th ed marines, where there really was literally no reason not to use a supplement from how the relics etc stacked up from the main codex. This current implementation is better and I think your suggestion of more sort of hard locks on units and detachments might be about right for the level of identity required.

Agreed. I think if they do this it's going to actually be a 'new iteration', not just trying to be the IW Legion as it was in 31-40k and Editions 2 and 3... If this is a Perty and Vashtorr book I actually expect it to be closer to Chaos Androids and Robots than Legionaries and Terminators. Further to that, I think the 'faction' might be better as just a 5th (Undivided) option for Chaos Daemons so that those players can make a slide toward using dedicated 40k units on the way to (likely) effective squatting by 12th edition?

 

In any case I'd fully expect them to also be an 'open ally' much like Chaos Knights or Daemons or Cult Marines so that other lists can bring in one or two of the new fun Zords or whatever if they want. As the 'arms dealers of Chaos' vibe was already started by Vash'tor, this could be more like an Agents release than a Marines supplement after all... and I wouldn't be opposed to that, really. I'll be more interested in cool daemon robots if I can just sprinkle them into my Doom WEasels than if I have to start a list from scratch.

 

The cool thing about the 'tech faction allies' vibe is that it'd give us room to play around with conversions for chosen deities and break outside some of the limitations on Cult lists as they are. Basically releasing 3-5 kits of 'friendly tech faction allies' gives all the Chaos lists some more options to fill gaps at the same time, and as a result would tap into any and all Chaos players rather than just a tiny fraction of them. I know that this is cynical and mercenary reasoning, but this is GW at the end of the day. I would buy Vashtorr tomorrow if he could be in WE. He's been on my 'maybe' list for a while, and I'd probably jump in with some Oblits and Mutilators if they could join as well.

 

Heck - as a supplement it could be given 1 detachment for every other Chaos Codex, so that the likely small number of data-sheets is balanced by the presence of those other lists in their entirety. That would certainly be cool and interesting, though it's very unlikely to happen because I don't think they'd want people to feel like they're forced into only 1 or 2 detachment options from the book. It's almost like they should figure out a way to offer codex supplements at lower prices than full codexes!

 

Cheers,

 

The Good Doctor.

As a player of IW with over 7k of IW models I would kind of ticked if they get the treatment that the cult legions got where they are severely limited in units. I wouldnt mind an expansion and maybe a special IW detachment similar to what the codex marines just got and maybe some additional units returned from the heresy like breachers, basilisks and Arquitors. Some cool terminator lord to direct a bombardment and storm the breach. But if it means cutting off existing models then it likely means they would cut off the vehicles and force the stupid dinobots and that is no Beuno. 

 

I currently run two what I consider classic and iconic IW armies, mass legionnaires and heavy weapons with terminators and landraiders or my actual siege breaker list which is 3 Vindicators, a Typhon, and Legionnaires and cultists. I have zero of the newfangled ugly dinobots and I dont think GW will push either of these play styles with any new IW specific updates.

[ChapterMasterGodfrey]

Is Vashtorr and the Dark Mech maybe going to get rolled into this?

 

Beside, Peter Turbo himself and maybe a couple other HQs I can't see enough unique units for a whole book. I hope this involes the return of the basilisk for the IW, that was always so cool.

 

At this rate though, what is actually going to be in the CSM book? BL, AL, WB, NL... Red Corsairs to step into the limelight a bit more?

[Jscarlos18]

Based on these rumours I think GW's plans are to split the SM and CSM factions when each Primarch returns, then fill the vanilla codices with all the generic/custom chapters/warbands. It happened with the mono-Gods getting their Chaos Primarchs.

 

 So with Perturabo the IW get their own book, Lorgar and WB get theirs in time, etc...

 

Some Loyalist have them already (BA, DA...), but wouldn't surprise me if Dorn or Corax return also splits the IF and RG from the main book.

This was my natural assumption too. But then I thought that that wouldn't be very accessible. Oh you want to join the hobby and play Space Marines (as i'd wager 75% of new players do), well now you've got to figure out what type of space marine you want to be... Just can't see that being marketable at all.

This approach seems more likely, especially with the rumour about Daemons not getting their own book.

Why, they've been doing it for 6 years so far with both types of marines and nobody has batted any eyelid. 

[ZeroWolf]

There is an extremely easy fix to making it accessible if GW really wanted to do it (they don't) and that would be to have the core SM/CSM rules be free. I'm thinking that the free rules would be bare bones just the rules and nothing else while they could still cater to those wanting physical with a print on demand book packed with new lore and new art work (ideally).

 

Then they could charge for the specific chapter supplement/full codex. I know you could make the argument that they should be free as well, but one step at a time.

 

Another way to do this, without going all free, would be to include a code in every edition launch/starter product that unlocked all the space marine rules on the app (and add a bit more flavour to it).

 

Crazy thinking I know but if GW keep pushing the prices of codexs up, then they're going to have to look at this because they'll be selling a whole lot less of them...

[Vassakov]

I suppose the question then becomes "How many units are needed for a supplement?" Most of the Loyalists are around 15-20 datasheets and 3 detachments, but they've also had the benefit of decades of individual attention in a way that the Traitor Legions, to be blunt, have not. Could a Supplement: Iron Warriors accommodate 15 datasheets? And all with new models? That's a heck of a release - EC and WE were what, 6 actual kits?

 

Perty

Warsmith

Multilators

"Siege" Squad a la Legion Breachers?

Some Cybernetica Robots?

Iron Havoc-esque unit?

Legion Basilisk?

Some other Daemon Engine type thing?

 

But then you run into a different issue, which is that I've just ported some HH Units into a 40k Codex, which is anathema to current design philosophy unfortunately.

It's fine to import a theme with a different kit, GW is ok with that seemingly.

Don't forget Vashtorr! Although he mot likely would be included in DarkMech instead if they ever get a range+codex.

Thinking about the rumoured upgrade sprue (and assuming it's like Nemesis Claw), the Night Lords sprue contains:

• 10 NL pauldrons, 3 blank pauldrons (gee, thanks), 1 set of Champion pauldrons, and 1 set of flesh-drapery pauldrons
• 11 wing'd helmets, 4 sans-wings
• Nostraman Chainblade + backpack flesh-cape
• Nostraman Chainglaive + be-flesh'd chest plate (with butcher knife)
• Paired Accursed Weapons
• Scoped Pistol + Envenomed Combat Blade + Flask
• Bespoke Chainsword + Voice Eater

Trying to create an equivalent:

• 10 IW pauldrons, 5 moulded Hazard Stripes pauldrons,* 1 set of Champion pauldrons
• ~10 (horned) skull grill MkIII-ish helmets, ~5 weird techno-mutant
• Daemon-Cybernetic Power Fist + backpack Servo-Arm
• Daemon-Cybernetic Hammer + bionic chest plate 
• Autocannon (bionic arms)
• Lascannon (bionic arms)
• Bespoke Bolter + Shield + backpack IW Icon

Something like that wouldn't even (technically) need a unique datasheet - though it would be nice to get a 'Siege Master Squad' (or what you will) with 2-in-5 Heavy/Special Weapons, and some ability that make Bolters attractive to field. (And the Servo-Arm wargear allowing the unit to combo with vehicles; though you'd want it to be different to the Warpsmith's ability.)

Using the Night Lords upgrade sprue as the basis is a good idea, @LSM. I'd take a stab in the dark (ho ho) that the non-Cult Legions have all had a sprue at least conceptualised, and they'll follow roughly the same premise of 'we can't justify a complete kit, but we can add some thematic elements to the basic Chaos Legionary squad', giving us a couple of mini sprues like the Night Lords ones:

 

 

If that's the approach they're going for, then I'd anticipate the release being folded into a Kill Team release, like the Night Lords. That would build on some existing Kill Team roles, and has a few bits and bobs that reflect this. e.g.:

• Shieldbearer – big breacher shield, heavy loincloth. Mark III-style head.
• Linebreaker – double-handed hammer/maul
• Comms-specialist – special backpack, hand with daemony-vox/dataslate
• Explosives expert/minelayer – meltabombs, mines etc.

... and then leans into the more specifically Iron Warrior archetypes with the remaining space, to create something that is more distinct/saleable than simply aesthetic tweaks. Iterating from the Night Lords examples, I'd expect to see something like these:

• Some form of techno-daemon/warp influence specialist – but no idea how this would be modelled.
• Minesweeper – A tech-specialist who detects and disarms traps.
• A pseudo-Berzerker – close combat weapons
• Special 'Warsmith-lite' leader – servo-backpack, hammer
• 'Dark apothecary'/quartermaster – a Space Marine equivalent of the Death Korps/Astral Claw body/geneseed-snatching nasties.

These are more speciafically Iron Warriors-themed, and thus GW get two bites of the cherry: once for Kill Team, and again as a new elite/specialist unit for 40k Chaos armies: 'Siegebastards*' to complement 'Nemesis Claw', 'Berzerkers', 'Noise Marines' etc.

 

+++

 

The alternative is the altogether simpler approach we see for the Loyalists, where you get purely aesthetic sprue. On the face of it, that seems more likely if there is an Iron Warriors-specific Codex coming, as it'd be weird for a 'special' Iron Warriors squad to come out for 40k prior to Kill Team:

 

 

Personally, I'd like to see an Iron Warriors Codex – it'd be a great place to gather some of the weirder 'technochaos' things together like:

• Negavolt Cultists  – amongst the few things from BSF that haven't been released as a separate kit, and seemingly ideal for the Iron Warriors 'cultist' slot.
• Vashtorr the Arkifane – a bit centrepiece that would fit in nicely.
• Warpsmith
• Venomcrawler – Currently only available as a single-pose together with Obliterators
• Obliterators 
• Mutilators 

... and they're a natural place to have Chaos bunkers/weapon platforms/barricades etc.

 

I'll take the rumour cum grano salis and not get my hopes up, but I certainly don't think it's beyond the realms of chaos possibility that we'll see something.

I'd only shy away from a Nemesis-Claw-esque Iron Warrior sprue being for Kill Team as Kill Team seems to have moved past "upgrade sprue teams" (and wholly into introducing completely original kits).

 

I do agree on the "Operative roles" regardless, though. 

 

My other thought was that as GW previously used the original "Legionaries Upgrade Sprue" to introduce Reaper Chaincannon CSM models (as opposed to converting with leftover Havoc bits), we're starting to look a little dicey when it comes to the Autocannon CSM (which was included in Shadowspear but has been OOP for quite awhile) and the Lascannon CSM (which... what, like twenty years ago? In the last Iron Warrior upgrade kit?). If they don't get models soon, I could see those options being removed.

 

(I guess I could rebase mine into Havocs, but it'd be nice to use the IW upgrades as an opportunity to sneak them in instead.)

 

//

 

"Siegebastards" >> "Siege Masters"

 

//

 

Not too sure about the idea of Mutilators coming for a Codex: Iron Warriors (and by implication not being for Codex: CSM), or the possible shifting of Obliterators from general CSM into IW specifically. Unless you can then ally them into CSM, which... at a certain point, it all seems to me to be more sensible to just do a Iron Warrior themed wave for Codex: CSM.

 

Or, for example, at the end of 3rd edition Age of Sigmar there were Battletome Supplements for Ironjawz and Darkoath. But come 4th edition, those new bits and bobs have been folded back into Battletome: Orruk [sic] Warclans and Battletome: Slaves to Darkness. So a "Codex Supplement: Iron Warriors" might accompany an early edition Iron Warriors themed little wave of models, before being returned to 11th edition's Codex: CSM. 

 

(For the record, Battletome Supplement: Ironjawz released on Sept 12th 2023 and Battletome Supplement: Darkoath released on May 4th 2024. Both were overridden in July 2024, which was okay as both had been free downloads on WarCom.)

I feel like these would be better served with an actual Dark Mechanicum Codex myself. Totally agree I'd like to see them expanded on though.

 

New Obliterators/Mutilators would be nice, as mentioned prior the current plastics look more like mini-Helbrutes than Obliterators. Venomcrawler I can take or leave but a proper multi-part kit could be cool for conversion fodder at least.
