I have the legend achievement and all campaigns on waypoint from halo 1,2,3,4 showing complete on legendary solo. I have reset my xbox after checking and no helioskrill armour i also have other armour i can equip such as nightfall that doesnt show up in my collection, any help is appreciated.
One thing that helped my friend and i was playing MCC for a bit and then we started up Halo 5 and we got our armor.
