The Hive Fleet Moloch site has evidently been around for a while, although I’ve just stumbled across it. I believe the Tyranid Kill Team has been featured in White Dwarf in the past. The best way to get a glimpse at the creator’s insanity is to view the site map – clearly they’re quite fond of Tyranids!
The highlight for me was the simple idea for a ‘Rocket Gaunt’ which is far superior to the standard metal Tyranid Gargoyles imho.
I really must get around to stripping my motley bugs and repainting them using the dipping technique that Dustan has tried recently.
