After painting the few Space Cadets figures in monochrome, I reminded myself that I had an unpainted copy of Space Hulk. It was unpainted because I was looking for a good color scheme for my genestealers. I think I was intent on painting everything in full color when I bought the game last year, but today, I tried a few figures in gray.
I think I will stick with the gray. In fact, monochromatic should just be my default setting for painting bad guys in board games. I will probably paint the rest of the genestealers later tonight. The remaining Space Cadet figures can wait (since I already have a full painted set for that game.)
The figure in the photo were all simply drybrushed, starting with dark gray and working up to light gray/almost white. The skulls were give an extra hit of the almost-white, as were a few of the extra sharp edges and accessories (skulls, wings, emblems.)
The terminators will get a heavy dose of rusty armor -- grizzled veterans. That should help speed them along, too. The terminator in the photo is gray because he is a mission objective, all of which will also be in monochrome.
Edit: Genestealers are done already! And here is the scheme I will apply to my terminators:
