Imperial Armour 1.0 is ready to go! Brace yourself for rampant typos and balance issues, this is very fresh 😛 
I'll be putting out a small errata update to the Core Book over the next few days as well, which will apply some tweaks to personal scale weapons and how they interact with vehicles.

Back at it again.

The preview looks fantastic and we've started a game using DH 3.0, so we'll be definitely utilizing this.

I have a question - since we will have a lot of dealings with voidships and cruisers and whatnot, would you be able to give some tips on creating your own vehicles for 40k? I have a bunch of old Rogue Trader splats and I'm not sure if you're basing your vehicle conversions off of DH 2e, and whether you can give me some pointers? Would be cool if we could give the option for non-military, more transport/voidship type stuff for this. 

It's a shame that 40k is locked with Cubicle 7 right now, because the work you've put into this could (nay, should) be bound in a hardcover supplement for Genesys.

Tried to give the autocarriage a lot of flavourful variants considering it's basically the generic civillian vehicle option. But naturally homebrew beyond what's in the book is encouraged.

Just popping in to say I am so relieved to see I'm not the only person who does this sort of thing during game design (and even session prep).
 
It me.

P.S. here's the vehicles I'm currently planning to include for the ground vehicle section. (Bolding stuff as I complete it!)
Achilles Ridgerunner Atalan Dirtcycle Atalan Wolfquad Autocarriage (civilian car) Baneblade Basilisk Chimera Armoured Transport Goliath Truck Land Speeder Land Raider Land Raider Crusader Leman Russ Razorback Rhino Salamander Command Tank Sentinel Walker Tauros Rapid Assault Vehicle Taurox APC Taurox Prime Veloxic Bike Not looking for this to be an exhaustive catalogue of every Imperial Guard tank ever, looking to just get the broad strokes relevant stuff, and prioritise stuff which might get some use in a Dark Heresy game. 
If anyone else has any other good suggestions let me know. Civilian vehicles are unfortunately pretty un-explored in 40k material, but Genestealer Cults vehicles provide some nice examples of what industrial vehicles look like. 

Here's some vehicle weapons. May add more depending on what vehicles I end up including. Everything here is planetary scale unless stated otherwise.
I'll probably gut out the prices and rarity for the final release as these are all purchased as part of a wider vehicle profile (vehicles specify what you can swap out for weapon slots), but I've calculated them for the sake of making vehicle prices easy to work out. 

That could be an idea, although I'm not sure if I'd need specific rules for each vehicle; there's not really any vehicles power weapons or meltaguns *won't* wreck.
Also, what do people think of these rules for running people over?

An alternative solution I've come to with some help from the Genesys Discord is this, which feels like a more elegant solution than changing Genesys' core mechanics for vehicles.
A new weapon quality to be added to Meltas, Power Weapons and other weapons which need to pose a real threat to vehicles without turning humans into a red mist on impact.
This basically would let me tailor how much damage a given weapon can do to vehicles, while leaving its damage to personal scale threats untouched.

I think the thing is, effectively in Genesys and Star Wars pierce *is* just giving them a higher damage value. The difference between a weapon with Damage 7, Pierce 2, and a weapon with Damage 9.... doesn't exist. Unless you're fighting an enemy with 1 or less soak, which is such an absurd edge case (it'd have to be a brawn 1 enemy with no armour), that it basically never applies.  It just gives the illusion of different stats while adding an extra layer of mechanical detail that doesn't really do anything. It's mechanical density for the sake of mechanical density.
I think Sturn's proposed changes do a good job of making Pierce actually *do* something mechanically. Because currently in 95% of real combat cases it's just bonus damage, it's the illusion of mechanical depth. Also, players should already be tracking how much soak they get from armour, it's part of their gear, which is recorded on their character sheet. 

Not sure if this is what I want to focus my attention on next but I felt like doing some cover and intro chapter work so I made this 👀

And here's a Google Drive link to all the individual chapters in a folder, for commenting on with any proofreading feedback/suggestions.

Keeping it to separate chapters for annotation should make things more manageable I think. Also might be somehow useful for people who want specific chapters on their own?

The third edition (I guess I'm calling it that now) PDF is ready to go! Huge thanks to everyone who has provided feedback, proofreading, etc while I've been working on this overhaul, it's been very helpful!
I would encourage people to download the PDF, as it is fully bookmarked and has toggle-able layers to facilitate easier printing. Those features don't work in Google Drive's document view.

Unfortunately I haven't kept an exhaustive change log for this one, but I plan to keep more detailed errata for future updates to this. But here's a broad strokes overview of changes made;
General
Whole book updated to a new, full colour format, aping the design of FFG's Dark Heresy Second Edition books.  Flavour text, player/GM advice and content in general has been expanded throughout. A lot more time is spent trying to contextualise things and explain mechanics, which hopefully makes it all a nicer read. Chapter I - Creating an Acolyte
The steps of character creation are given a lot more attention; mechanically these haven't changed, but they are explained better now. Careers have been renamed and mostly redesigned. I've gone with much more generic names, primarily lifted from DH2e with some tweaks. They all have a set of suggested talents and gear now, like in Shadow of the Beanstalk. Two new careers added; the Fanatic and the Ace.  Step 1 - Determine Background has been added, with some useful questions to consider when making a new Acolyte. Chapter IV - Elite Advances
 Wyrd have been removed. Unfortunately couldn't find a way to make it mechanically meaningful enough to keep. Wyrds can be represented pretty well by just dropping only one rank into a psychic discipline and role-playing accordingly. Added Gland Warriors. Added a set of basic talents for Untouchables to expand their character options. Chapter V - Armoury
A new Haywire weapon quality is added, functioning similarly to Sunder but specifically for electronics.  Low-tech weapons expanded - added Bolas, Bow, Flintlock Pistol, Musket and Sling. Plasma caliver and arc weapons added. Various other gear added throughout the chapter - I unfortunately did not keep a list of what I was adding during development, but there's a lot of cool stuff now that wasn't in previous editions. Chapter VI - Narrative Tools
Downtime Encounters have been renamed to Interludes. Some tweaks to the Interludes rules. Chapter VII - Psychic Powers.
This chapter has been entirely rewritten to be standalone - you shouldn't need to reference the Genesys Magic rules when using this chapter, as I found that this was a huge chore in play, flipping between the two books.  Some powers have been tweaked, with some options added. Perils of the Warp is now more deadly; extra despairs add +10 to the roll, not +5. Chapter VIII - Corruption
Corruption checks have been changed to be something that occurs at the end of an encounter, not during.  Chapter X - Allies and Adversaries 
Each adversary entry is given its own page now, with a lot more room allowed for flavour text and game-play advice.  New section for servitor NPCs so they can all be found in one handy place, along with some slightly tweaked rules for handling servitors. Suggested psychic powers are detailed on every psychic NPC's profile. Some general balance/design tweaks to a lot of the profiles. The first and second editions had an embarrassing amount of typos and rules issues, a lot of that is fixed now.

Yep, I'll give the character sheet a look over some time in the near future. Not sure if I'll do a total redesign or just update it to be more in line with the current mechanics, I don't really like the look of it currently but designing character sheets visually isn't really my strong suit.
