So getting back to the little info we have on the mechanicum thus far; it's been my personal opinion that the ordo distinctions are being binned in favour of a generic
HQ and Ordo headcannon like they are some 'non-marine variant' legion rules.
Behold the only official info we have...
But to a Reductor player thats got a lot of info already.
deleted units - the 'Ordo Reductor artillery tank' is missing, as is the 'Ordo Reductor Minotaur Battery' (now available to anyone in the pdf) and so is the 'Magos Reductor' as well as standard pattern indentured Imperial Knights. The venerable 'Macrocarid Explorator' is similarly absent along with all three flyer options (primaris lightning, avenger strike fighter and arvus orbital lighter), Archmagos Inar Satarael and Archmagos Draykavac. We also know from playtest leaks that the Thanatar Cynis has been deleted; the Thanatar profiles have been integrated but the Cynis' weapon option is gone.
Weird Naming - Calleb decima is awesome and he has a double profile like ravenguard primarch; to those who have forgotten or didn't care he had an upgrade which would alter his profile to represent him after the Isstvan 3 atrocity called 'decima invictus' - the key point of this was it didn't allow you to take it for his alternative unit choice variant where you could represent the Ordo Reductor at their most desperate and scrappy.
The great point of that was it allowed you to take a single heavy support choice with the 'tank' type from the legion marine unit list; this was big because it was the only way an Ordo Reductor force could use a Landraider Achillies and was the only mechanicum faction to be able to.
strange additions - still not found any answers to what a 'Arcuitor Magisterium' is but i'm guessing they are the ham-fisted inclusion of the
40k unit 'electro-preists' since they're an elite unit type in
40k too.
In the playtest rules were 'kharax seige automata' which seem to match the setup of the
40k kastelan robot
page numbering - so each new section in an
HH book get a single page dedicated to a symbol and the title to the section. this can be seen in the page numbering for the ordinatus where the unit has a single page but there is a missing page between the ordinatus aktaeus entry and the start of the appendicies..
this makes for..
5 pages dedicated to using warlords of the mechanicum
1 page for Calleb Decima
1 page for Magos Dominus
1 page for Magos Dominus on abeyant
double page spreads for both Archmagos and Archmagos on abeyant
The appendices section will likely have a title page for each sub-section leaving..
4 pages to explain cyberthurgy
3 pages for 'orders of high techno arcana'
8 pages of mechanicum special rules
4 pages of 'persona schizmata'
8 pages of divisio tactica titan legions
15 pages of divisio tactica questoris household
i believe that the appendices section is largely fluff because i don't believe
GW would entertain telling players to consult the last editions books for fluff - naturally a bunch of it will be weapon profiles, special rules and unique equipment but i think the divisio tactica are just sections on using an allied force of IK or Titans alongside the mechanicum as allies and a bunch of fluff about how they worked alongside each other and whom.
The reveal of the contents of the mechanicum book is going to be a pivotal moment but i have many doubts and not a lot of faith in the poor sod which had to throw away all Alan Blighs work.
Actually, feth that guy; he deserves it.
