Space Hulk rules for Genestealer Cult miniatures?

[Kastor Krieg]

As above - is there any source of official or good fanmade rules for GenCult rules?

[Wrath of Bruinen]

Yep - December 2017 (can’t see a number on it, I think it’s from the days where they stopped numbering issues)

 

It’s got rules for using GSC and a special mission

Googling "Space Hulk Bible" gets you all sorts of old hybrids that are pretty straightforward to make work with the latest editions.
