Dark Mechanicus- Genebrute 1
During the Stygian Wars the Dark mechanicum bred genetically altered hulking brutes. Pumped full of growth hormones and other drugs they grew quickly to monsterous size. They were then altered being fitted with various close combat weapons as well as drug injectors to fuel them with rage as well as pain medications to enable them to ignore most wounds and continue fighting to the last. Genebrutes were ferocious in combat where they were often used as a forlorn hope shock attack force.
For game purposes I use this model as a spawn with the mark of nurgle.
