Achievement not Unlocking

Unfortunately there is no Reach Help/Support forum section to report issues so I decided to post here. I have completed the campaign on Heroic difficulty, yet the achievement for doing so will not unlock. Can anyone out there tell me how to solve this? 343i?

I’m not saying this to be a troll, I’m offering this as a suggestion that might be able to unlock it. If it glitched out in such a fashion, as much of a pain as it will be to do, you might have to actually complete the Reach Campaign on Legendary to get that achievement to unlock as well as the Legendary achievement as a bonus. If you want to get through that quicker, then get a friend and do so on Co-op Legendary. Give that a go and see if that works.

I hope this helps and have a nice day now.

Yeah, lizking is right… That might be the only way to do it. I have had that problem with other halo games, and thats how i fixed it.

Well then… As long as it works! Guess it’s time to unlock Monument To All Your Sins again, but on XBOX one.
