Hi I'm new to Dark Heresy and finished up my third session last week.
The acolytes are investigating a cult and I was thinking about switching it up and making the inner circle of said cult a chaos worshiping genestealer cult. Problem is I'm not super familiar with the lore and I don't have the creatures anathema supplement.
I wanted to know if Genestealers are a bit much for tier 3 acolytes. I know they can be dangerous even for Space Marines so I was concerned about this kind of threat. (though it does seem like the sort of thing the Inquisition would specifically look in to)
note: Normally I'd just punch down some stats but I think one of my players is pretty familiar with 40k lore and will call me on it if the genestealers aren't represented well statistically.
You over enthusiastic munchkin!
