I was on for a cheeky bit of Guardians this morning, and I do not, nor have watched Halo:Nightfall. To my surprise, I find I have the Nightfall armor, but not the helmet. Is this some kind of glitch or is anyone else getting the armor only?
You must have opened a REQ pack containing the armor piece.
the application on the xbox halo waypoint and there is the film that you can buy
