Hey Dakka,
I've been trying to come up with a way to run a genestealer cult-themed
40K army off and on since 4th edition (disclaimer, the old "Space Hulk" game of genestealers vs.
DA Terminators was among my first experiences with the world of
40K)... but I've never really been happy with most of the (few) forgeworld attempts ...
So I'm thinking that (since the allies matrix doesn't let me take 'nids as allies to an
IG army

) that the best way to try to run this is through some fairly massive kitbashing -- some things I've done before, but seem to have lost the models...
I recon that since most of the lists I've seen in the Army lists forum for 'nids include a Tervigon, that I'll need termagants -- which I was thinking of hybridizing with some genestealer bitz, termagant guns and
IG bodies (my previous attempt used some Ork bodies, but every player I showed 'em to said "ork-a-nidz" which was
not what I was looking for)...
I also had an old-school zoanthrope model (back then they still had claws) to which I added a genestealer face and some other bits to be a walking tyrant
But since 4th Ed's models have the 'nids looking more unified, I'm thinking my new modeling challenge is going to be adding human/human hybrid models to fill out the force.
One idea I've had (and used in the past) was to model some of the multi-wound models (like warriors) with mixes of bits from
IG & 'nids (using extra
IG bodies to represent the extra wounds)... turning a warrior w/ venom cannon into the equivalent of an
IG heavy weapons team
But I'm a bit lost as to how to represent tervigons -- obviously a genestealer cult army isn't going to have something just generating new cultists, right? ... or do I maybe take a theme from Aliens and model the tervigon as
IG troops that have been implanted by genestealers then put on hold until needed for the fight?
Anyway, I'm mainly looking for modeling advice here, but I'd also like advice on which 'nid models are worth making the modeling stretch to include in my army...
Many thanks in advance
