I just saw all the Halo videos from Halo channel, in order to receive an armor and a helmet, but it’s not happening… do you know something about that…? I just received the emblem from halo channel… thanks.
Not 100% sure what you are talking about. Here is a list of all the req packs that I know of that can be unlocked by watching videos. I hope it helps.
1 - To get ‘Vengeance Assault Rifle Skin’, Check the Halo Experience website and watch all 10 videos (5 for Master Chief, 5 for Locke).
2 - To get ‘Halo Channel Emblem’ REQ pack, Download the Halo Channel app and watch any video on it.
3- For ‘Nightfall Helmet’ REQ pack, Watch the fourth episode of Halo: Nightfall on the Halo Channel app.
4 - ‘Nightfall Armor’ can be obtained by watching all five episodes of Halo: Nightfall on the app.
i just got the number 1,2,3, but 4 and 5 i saw the videos and nothing 
, may be a problem? with the app? I saw them in halo channel app in xboxone, need to see them maybe on a webpage?
i dont think itll let you on the halo experience anymore i tried it just said webpage not available
