Classified halo waypoint requiem armour

Hey all

Just updated halo waypoint again on my Xbox and noticed a classified section which allows you to download additional armour when you complete specific achievements on spartan ops. I have looked for the section 3 news on halo waypoint .com but nothing comes up. Anyone had any luck.

Trying to find out how to unlock it as well.

Check this part of the forum out
