I’ve watched halo nightfall like 4 times already and I still don’t get the nightfall armor 
Just watched them all today while doing other things and got the same issue with not getting the armor or anything else for the MCC.
you can equip the armor through the pc version of halo channel but it doesn’t technically unlock it in game. Broken much?
Same here. I actually watched all the Nightfalls when MCC released. I watched the first two episodes, then waited for them to release the rest over the next few weeks and watched those, too. I never got the armor. So, I just watched them all on my Windows phone, using the Halo Channel app and still don’t have them. I’ll try once more on my Xbox, tonight but I’m sure it will be fruitless. At this point, I’m going to remember the lines of the movie ,word by word.
