The ancient DoC machine spirit awakens! Internal work resumes!
It is not uncommon for a Genestealer Cult to enlist the aid of mutants in its revolt against the planetary Imperial government. A range of mutants will feature as support for the Genestealer Cult but this unit represents a primitive mutant tribe or clan which has formed in the planet's wastelands, dense jungles or underground. The Genestealer Cult often forges covert pacts and alliances (for it would greatly arouse the suspicion of the planetary government and disillusion the masses ought such dealings be known) with large groups (numbering in the hundreds or thousands) of such mutants who possess some form of sentience. Often, the Cult benefits greatly from making extremely cheap payments such as a supply of bones, wood or textiles to the impoverished and mentally deficient mutant tribe and receive powerful, expendable foot soldiers in return. Such troops oft wield primitive but explosively dangerous (sometimes to the user) stub guns which have been cobbled together to provide heavy if inaccurate fire support to cult troops and tie up enemy units in melee.
Looks like a blue wookie now. :)
Brilliant modding, can't wait for final product. Also, just an idea, you could create more mutant units like this and make your own Lost and the Damned faction. And don't forget the gibbering hordes as well :)
