I am making a Warhammer 40,000 Space Marine cosplay. Specifically the Emperor's Champion of the Black Templars. I found myself being linked to a forum on "Obscurus_Crusade" where a gentleman in Sweden, I think; it's hard to tell, who had a semi-tutorial on how to build Marine armor.
After a long time of mulling over several choices for color schemes I decide to make my costume out of the first Marine model I ever bought.
