I beat legendary campaign solo today while I and I never recieved my armor set for it. I was offline while I did this acheievment but that should not matter at all when receiving the reward for it. I should not have to repeat all of campaign while I am online just to get the armor set. I have the acheivments and everything on my account I just dont have the armor. Has anyone found any fixes for this bug?
Nope.
Go back and do it all online like the rest of us had to.
I think 343 is at least looking into it though.
Restart your game/console. Should show up then.
You do know that you cant get Mk.VI by beating it on Legendary Co-op too right? I’m doing it solo then co-op legendary for cheevos.
EDIT - have to do it online, sorry.
It’s part of the commendation unlocks, not unlocked through achievements. So you have to play it online. Also there are many other topics on here regarding this issue.
The armour is actually tied to the commendations for beating the levels/game on legendary, not the achievement.
I did mine online, full solo campaign, shows on waypoint ive done taswel and still no armour set and this was on launch week. To this day still no mkVI

Have you checked your commendations? if there’s one missing then you’re going to have to replay it.
