Doomguy is from Klukva Miniatures. Very clean resin casting, quite easy to paint.
The two ‘Elite Guard’ Nazi ladies are from Thrilling Tales’ She-Wolf characters pack. The models had a lot of flash but they’re old school in design and quite fun to paint.
Caleb and Corzo are from Wargames Foundry and their cowboy line – one of the only lines that has a cowboy wearing a poncho. There are plenty of good Calebs out there, but they’re all part of bundles, and none of those bundles have a passable Corzo in them.
