Heirodule head is simply a gaunt head with a knife split the middle of it and stretched out, then mucho greenstuffed the bridge, crest and front of jaw back in, sculptind teeth etc. I think I had another thread for it? Here's some more dule pics anyhow

The list was from the top of my dome:
3x (4) Warriors
3x (4) termagaunts
5x (4) hormagaunts
2x (4) raveners
3x (3) assault broods
2x Hierodules
1x (6) genestealers
1x (6) genestealers + broodlord
I didn't do well because I was a bit scaredy pants to march into gunlines in the first turn (and with a few failed activations to that effect). Also because the giant phants are volcano bait

The creatures protected the BTS pretty well, i did lose BTS in the last game though, just.
