One of the folks over at FauxHammer
wrote a build guide/review for the Indomitus box, and helpfully included some colour-coded sprue pictures to assist (and in places warn!) those who already have a box in their hands (hi @James
!). They have also kindly allowed me to post up the images, which was really quite nice of them!
Below you'll find the sprues themselves, but the accompanying guide is linked above.
