If you are familiar with Wargames Atlantic, you know that they make an eclectic mix of historical, fantasy, and science fiction minis. Primarily in hard plastic, but they also have an STL shop/program. This is their first crowdfunding thing – and the first time they are releasing a whole range at once – most of the time, they release a kit, and if it sells well enough, they may eventually release additional kits.
Their Science Fiction line is called "Death Fields", and there is talk about eventually creating a rules set for them. Many of their customers buy them to use as humans for 40k – imperial guard, cultists, renegades, etc., others use them for games like Stargrave, or minis agnostic rules=sets. They mix and match pretty well with Stargrave minis, GW humans, etc. They are more "heroic" than Wargames Atlantic's historical minis, but many people are happy with kitbashes/conversions of the two different types.
The Damned faction is a post-apocalyptic style renegade faction – and looks great for a lot of renegade/cultist uses.
