There are a ton of armor options in Halo 4, most of which are unlocked by ranking up, getting commendations, and completing all ten ranks of specializations. Of course there are the exclusive armor sets as well, listed separately.
I’ve compared this list to the complete lists in the dev videos, and I think I’ve listed all of them, but if you find some missing please leave me comments.
These armor sets only include helmet, chest, and both shoulders, with the exception of the exclusive armor sets, which come with one of every piece.
