Haven't got my helioskrill armour

I beat halo 1, 2, 3 and 4 on halo mcc. I’ve been waiting for my Helioskrill armour and haven’t got it. I completed it a week ago?? How do I get it

You have to beat them on Legendary difficulty

Did you beat them on Legendary? If not your outta luck!

Your campaign stats show you’re missing a bunch of levels.

If you don’t have the legend achievement then you can’t get it.

No, just Halo 1-4.

Also make sure to be connected to xbox live when completing the missions or they won’t count.
