After seeing the new Mongoose ones released, I broke out my Harlequin ones and started basecoating them.
If the new Mongoose ones are anything like some of the SST ones, they might be larger than the Harlequin models.
Overall, very few models have a likeness to any of the main characters. However, most look very good as models for just player characters. Rather than Captain Lochley, just call her Female EA Officer #1 (the one that's supposed to be Ivonova, just call her #2 or visa versa).
So far I've now have an assortment of other aliens as well, like Drazi, Gaim, Soul Hunters, and Llort.
Now I'd love to see what a Gaim Warrior Caste would look like, it'd probably have some alternate uses for SST RPG.
