Freaking buddha, the hell is that avatar!? It's great! They should make that a "skull" on Halo Infinite, the "derpy grunts" that would be great! Also bomb build!
It is a great helmet. - When I asked I remember him saying it wasn’t for sale but then I saw the STL files being sold up on Etsy so I'm not sure if he is still selling them or not.I know I'm late to the party, but man that helmet is incredible. I've been trying to kitbash a hybrid 3/Reach helmet exactly like yours for almost a year out of Reach models and you go and do it in your opening shot! It's based on the version in the CEA terminal cutscenes, isn't it?
I don't suppose you'd be willing to share the STL file, or maybe a pepakura for it? I'm in the process of planning a Package/Infinite/Reach hybrid suit and that helmet is the missing piece of the puzzle.
