These chaps have to be among the coolest of the Rogue Trader era Citadel miniatures. I think I'll give them a paint job this month along with the rest of the genestealer cult. I imagine that when it comes to game time I'll use a blend of the Tyranid and Imperial Guard lists, which seems to be a common casual (i.e. non-tourney) solution, and these can sub as heavy weapons teams. Either that or I may retro-fit the rules from 1987!
