Wow, they are tiny! I thought of the Darkest Star figures as being on the smaller side of 15mm (judging by the few Spec-Sec figures I have) and yet these figures look like children in comparison.
They’re almost tiny enough to make me wonder if there’s any chance they’d go well with the “large 12mm” infantry from the Heavy Gear Blitz range. If they do, I’d be interested in buying some, but that’s still a very big “if”. It doesn’t take very much of a scale difference to make a big discrepancy at this scale/size range, unfortunately.
At any rate, I could see them in some sort of self-contained mini-project, paired up with a carefully chosen range of diminutive 15mm aliens. Maybe the Khurasan Chewks, the Critical Mass Kaamados Squamata or the Ion Age Maligs (although the lattermost might have to be redefined as old-style Space Orks rather than goblins/grots, given that the Ion Age range is very much on the larger side of 15mm). Finding suitable vehicles shouldn’t be much of a problem, as long as one steers clear of the larger ones.
