Just finished the Campagne Solo on Legendary and dont got the Mk 6 Helmet 
I got the Archivement and the Avatar Helmet
What can i do 
?
anyone who have the sam eproblem ?
I played legendary co-op with 2 other people and they both got the armor but not me. We all got the achievements, but I just didn’t get the armor.
Glad to know it’s not just me.
