I beat the game on legendary Solo and I do not have the armor…People have told me this is what you have to do to unlock it.
Is there anything else to do?
I’ve heard that Legendary solo could unlock it, I’ve also heard that getting the achievement for co-op unlocks it. Try that.
Check your campaign commendations, it might of not registered some of the missions to be completed (This could be due to not being on Xbox Live… etc at the time of completing that mission).
If some are not complete then the bad news is you will have to re-do that mission, the good news is it will then give you your Mark VI set.
If you have the achievement for soloing the campaign on Legendary then (in my opinion) you shouldn’t have to do certain missions again just because there system didn’t pick it up… They should keep it where you can see which you have completed but as soon as you get that achievement they should be able to detect that and then give you your armour… Experiencing the same problem and I shouldn’t have to do the missions I have already completed all over again. (Because its stressful and I would like to play multi player, not spend all day re-soloing campaign levels).
