These are thermic plasma conduits (2 packs) and regulators (1 pack) from GW. I think they were originally sold for use with Kill Team? But I intend them for use in various generic sci-fi skirmish games.
I started off with a base coat of black gesso, then a heavy drybrush of "rough iron" paint (an Army Painter paint color) for the main overall color which gave it a nice heavy duty industrial look, then various bronzes/coppers, blues, reds and gray, to do a bit of detailing. I was trying to keep things fairly simple, as game pieces rather than focal points for dioramas or the like.
So I set up assorted figures from my collection of sci-fi minis - just randomly, no actual game in progress (so far).
