For the most part, I took the 6th edition Chapter Tactics that Forge World provided for these Chapters, and I adapted them to Shadow War: Armageddon. For Chapters that have identified Legion lineage, I used the skill progression from those Chapters as a baseline, though I tried to apply some tweaks here and there in order to introduce some (very minor) differences. A few of the Chapters simply use their predecessors' Chapter Honours (e.g., the Novamarines are among the Primogenitors, so I reasoned that they follow the Ultramarines rules exactly). Others are very close to their predecessor, but have minor adjustments to Chapter Honours or skills or both. And some were very distinct (e.g., the Executioners are almost nothing like the Imperial Fists).

I've tried to keep balance on par with the main Space Marines Kill Team rules, but I'll need other eyes to help me with that.
I have an idea that these rules might include campaign rules, at the very least a series of scenarios to play out shadow wars (i.e., squad/team level skirmish battles) within the setting of the Badab War. These might potentially include a modification of the Shadow War: Armageddon campaign rules (though that might be nothing more than changing "Promethium caches" to "victory points" or "campaign points" or somesuch. That's way down the road, though. For now, the focus is getting these rules accurate and balanced.
Any input is appreciated.
