I will say first that the player models in halo 4 were much nicer, so any armor that did look good fit better than in 3 and reach (where a lot of things were very bulky). Overall the armor in halo 4.... Was just hideous. Especially the helmets, I could count about 5 decent ones and only 2 or 3 good ones (2 of which were locked behind DLC). They went far too alien and impractical with most of them. I haven't seen any of the halo 5 armor yet, but I certainly hope it looks more realistic and not just some "we threw a bunch of junk together" helmets. And they better have Mark V and ODST in there from the start this time.
