Base Locus

Hey I recently saw a pic of the base Locus helmet. Unlike the one that came as a preorder bonus from Mighty Ape which had a sort of X skin, this version just had a single stripe running down the middle of the helmet. This is by far my favorite helmet in the game and I was just wondering if anyone figured out how to unlock this in-game variant. To clarify once more: I am not asking how to get the locus helmet that came with a preorder from Mighty Ape or from the 7/11 game. The version I am referring to looks like this:

first ive heard of it :stuck_out_tongue: if we can ill be so happy its my fav helmet in any halo game aswell
