I beat the campaign on heroic to unlock CQB helmet but I’m not sure where to unlock it at
Well that depends, if you are on Xbox One then no and if on 360 then maybe. I heard rumors that even after 343i updated their halo waypoint, players could still unlock the armor provided but again it’s just on a rumor. On Xbox One for sure you cant sadly as I wanted to unlock the security chest again.
You can still obtain the armors through the Halo Waypoint App on the Xbox 360. Once you have them unlocked on the 360 Waypoint App, they will be avaliable in the game, either on Xbox 360 or Xbox One.
The Halo Waypoint app on the 360 has been having issues for me. I have all of the games and the consoles but the stupid CQB helmet has not been unlocked for me either.
it sucks that 343i doesn’t care about updating their 360 stuff anymore.
