Borderlands 1 and 2 gun manufacturer. Their paint scheme in Borderlands 2 has a black and white checkerboard pattern all over everything. They always do explosive damage or increase your resistance to explosive damage.
Again I must say I tend towards a loathing of much cosplayery but mostly because it's awful in concept, execution or is just way too much insight into the players personal intimate fantasies; well to me anyway. However, every once in a while a true gem comes along and you folks are it.
My kudos to an excellent execution of a very difficult endeavour given how hulking big Orcs are compared to puny pinklings, and well done for going with face masks and not merely painting ones face green which would have ruined it.
The armour is most well done, I'm strongly reminded of Blood Bowl for some reason, think it's the seated lads helm.
