So I have recently found out there are achievements directly from Halo MCC to Halo 5. I have been trying to unlock the “Mark VI Gen1 scarred”. Armor set for a while and I have completed the requirements for the full set but only received the armor. The helmet is nowhere to be found. Can someone help?
In Halo MCC, you unlocked the achievement “your journey begins,” correct? If so, you should have both the armor and the helmet. Based on your problem, though, I can only assume that re-installing Halo 5 might fix your issue.
