Hey Guys,

I just wanted to know if I could incorporate stuff from the 30k Mechanicus stuff alongside my 40k Mechanicus army. Any help is appreciated.

You can not. Some people will allow you to use a 30k army in a game against a 40k army, but you can not just throw random 30k units into your 40k army. They're entirely separate army lists, and trying to combine the two is like asking if you can put some orks into your space marine army.

unless they are units in an IA book, no. There are a lot of models from 30k that you can find in IA books.

Google it bud, the list is very extensive, but to the original question, the mechanicum list is very fleshed out, you don't need to incorporate the 40k units into it, the 40k list is also quite fleshed out and until the rumoured imperial armour that adds the 30k mech units to the adeptus mechanicus comes out, you cannot mix.

I would suggest simply using a 30k list in 40k. Works quite well.

Depends what units you have really
Magos->Dominus
Castellan robots->Kastelan Robots
The Giant Castellan Robot->Imperial Knight (are they around the same size?)
Tech-Thralls->Skitarii
Or you could just field it as a 30k army, as long as you have full rules, other players dont mind as its something new(ish)

Play your 30k lists as-is and your 40k lists as-is. I'd play my 40k against your 30k stuff. Mixing and matching isn't a thing I'd allow, other than stuff from the IA books, like:

1. Imperial Armour Volume One Second Edition - Imperial Guard
2. Imperial Armour Volume Thirteen - War Machines of the Lost and the Damned
3. Imperial Armour Volume Two – Second Edition: War Machines of the Adeptus Astartes

While there are the aforementioned issues with actually using them as 30k units in a 40k Army List, you could probably use the models as proxies.

I thought you could actually do that. There is an allie matrix which you can use to combine pretty much everyone with everyone else. The golden rule is pretty much ask if it's ok and go on with your stuff.

You will not find the Mechanicum (nor any other 30K army) on the 40K ally matrix. Just like no 40K army is on the 30K ally matrix.

30k is a separate game with different missions and balance. A 30k Ad Mech army is actually at a disadvantage him 40k. I play 30k Ad Mech, everything is very expensive points wise. It's extremely difficult to compete with the sheer amount of models the enemy can put on the table. At 2500+ points where you get access to better LOWs is where it starts to even out.

I also believe most IA's have a their Table of Contents posted on the FW site in the previews. Have a look, then head to 1d4chan and look up descriptions.

I just emailed Forgeworld about this topic. I dont want to do it because of powerful units and what not. I just want to do it because it would be cool. I could come up with some really cool backstories on why my forgeworld had machines from 30k. Their are also arguments for both sides of the rules debate. But theirs nothing in the Horus Heresy book saying I cant.

Just found this on the Forgeworld Horus Heresy: Book I...so as long as your opponent is cool with it then you can play them

Q: Are the armies and units in the Horus Heresy books by Forge World meant to be used in
games against regular Codex armies, such as say Grey Knights or Orks?
A: While Forge World’s on-going range of Horus Heresy books and their game content are all
designed to use and be compatible with the Warhammer 40,000 rules, they have been fine-tuned and
focused on playing battles in the milieu of the Horus Heresy rather than in conjunction with the
Codexes representing warfare in the 41st Millennium, and this will remain the case.

Designer’s Note: This means that while you are, of course, free to have fun and play games against
your friends using any forces you like, and Horus Heresy forces will be broadly ‘a fair fight’ with
Codex forces of the same scale, certain rules anomalies and inconsistencies may be thrown up that
you have to deal with, although these should not seriously affect the game in most cases. (For
example, certain units, such as those with the Stubborn special rule are at a premium costing in
Horus Heresy armies over their regular Codex counterparts, owing to the results of play testing
within their own sphere.)

There is, it's called the force organization chart. 30k models have their rules in a different book and are part of different FOCs. Do you see a thanatar or krios in the skitarii or cult mechanicus codex? They specifically say "models in these books are not meant for unbound play". What does that mean to you?

That quote just says you can play a 30k army against a 40k army. It doesn't say you can include random 30k units in a 40k army...

I know that. I wasn't planning on playing unbound. I never even suggested it. My OP wasn't exactly specified to playing a detachment. I figured people would assume it.

Of course there is, because they are two separate army lists. 30k admech and 40k admech are like 40k orks and 40k space marines. You can't put 30k units in your 40k admech detachment just like you can't take a squad of boyz in your C:SM detachment. At best you could ask your opponent if you can take a 30k detachment and a 40k detachment in the same army, each constructed purely from the appropriate army list.

I don't get where you guys are getting the idea that i'm putting random units into a 40k detachment. If you read the above statement you can see that I clarified that I never intended on doing that.

Uhm... You can take a squad of boyz in your Space Marine army. In fact, you can take a squad of boyz, a Bloodthrister, a single Annihilation Barge, a random Eldar Farseer, and a lonely Tau Shield Drone in your Space Marine army - you just have to play Unbound and be done with it.

I want to play a Adeptus Mechanicus army of awsomeness. It would have a skitarii detachement, cult mech detachement, and a 30k age of Darkness detachement. Its going to be a tournament winning list (not intentionally at least). I just want to run all the stuff that I think is cool.

I see.

Most tournaments aren't going to allow 30k lists, though.

Thats not a problem for me. I just want to make a really cool themed army. Leave the tournaments for my other armies.

But you will still have the issue I brought up earlier to deal with:

Honestly if it is something you want to do, and you can find people to be cool with it to play against, then there should be no issues and do it.

@OP: it all depends on the friends you play with. Our input is fine and all, but the bottom line when "bending the rules" is whether your opponents will be content to play against your army.
