Mantic enforcers are another reference point for power armor.
@William Redford if the ninjas are any good, you wouldn't expect to see them, would you?
A set that could make classic Rainbow 6 style figures would be nice. The 6:Siege minis from that kickstarter showed that the series is quite a distance from its roots.
@Frank Reischmann eisenkern seem a little heavy for that. I have both eisenkern and raumjaegers that I plan on using for a skirmish game idea I am working on. I really like the look of both sets.
Here are GCPS:
While I wouldn't complain if WA did a box, since more space marines (not 40k) are always good, you could look at Mantic's GCPS. I think the aesthetic is decently close.
I suspect you would start with unarmored male gladiators as a box, then expand from there. Some of the armored types you might be able to kitbash in the meantime.
I was recently curious about roman gladiator minis. Looking around, I didn't see many options. Crusader (I think) had some, but they were metal and the styling was a too old-school for me, personal...
When these were announced, I was excited. When I saw the price, I thought, "Wow, how many are in the box?"
Neat looking minis, not going to touch them at those prices.
They are at each others throats until the Raumjaeger show up, then they work together for a bit.
