Legendary Campaigns Completed But No Achievements

[edit: i went back through the games with all skulls turned off and score turned on after OP and unlocked the achievements]
I recently went through all of Halo MCC campaigns on legendary and completed them getting all Skulls and Terminals, but I have not received the corresponding achievements for these actions. I have unlocked multiple achievements for completing CE missions on Legendary with specific requirements, such as Walk It Off, How Pedestrian, and Beachhead just to name a few. The issue seems to be that the achievements for completing the Halo CE campaign haven’t unlocked which in turn has caused several others to not unlock.

Links to screenshots I took for validation:

I’m not the only one having this issue, Raptor125 and Albino Wooky (both in my friends list) have been dealing with the same issues. I believe Raptor125s issues have fixed themselves, but Wooky and I continue to not receive our achievements for what we have accomplished. I also completed The Maw on Legendary having not flipped my Warthog, and I’ve seen all missions in Classic and Remastered. Which means I should have “This Side Up” and “Before And After” achievements unlocked as well. It sucks that I have to post this thread just to unlock some achievements, but I really don’t want to be forced to go back through CE on Legendary again. Anyway if you guys could just fix the issue and unlock all the achievements for Terminals, Skulls, Missions, and Campaign Complete that are still locked I would really appreciate it. Just so we’re clear my Gamertag is DERK 91.

Actually if you were to unlock the 2 Skulls, 1 Terminal, each CE Mission Complete, and Legendary Campaign CE then all the others should unlock as well.

Just gunna confirm my involvement now. I’ve looked into it, and it seems the missions Two Betrayals and Keys will not give me the achievements I have met the prerequisites for. I’ll be very nettled if I can’t get that beautiful Helioskrill armor in halo 5.

Okay, it’s been almost 2 months and I haven’t recieved a reply, a message, or any form of support… wtf!!! The achievements are still locked and i’d really like to have them 343i.

I have the same issue. Completed all the missions in every campaign on Legendary and only certain missions are registering as completed for the achievement. I even went back and replayed some of them, but it still shows as incomplete. I want that Helioskrill skin in Halo 5!

Some people over on r/Halo are compiling a list of things to check out in case you haven’t been able to get the achievements. Not sure if this helps or not, though:

> Thanks to /u/Prod1gyHero1 for pointing out an easy way to check what you’re missing. Which should make the rest of the troubleshooting section unnecessary
>
> - Go to Waypoint, sign-in, check your service record, and make sure Waypoint lists each level as completed. At least one level should show as incomplete.If that didn’t work you’ll have to look at your achievements to narrow it down.
> We can do this by going to xbox.com and signing into your account. You can use ctrl+f to search for “Halo CE:” for example and highlight all achievements from that game.
>
> - First check to see if the achievement says “unlocking” in that case all you need to do is wait, this shouldn’t be happening as often as it used to, but it’s good to check anyway
> - Ok so if you’ve got all the badges but still no achievement you need to check the status of other achievements to see what level(s) the game didn’t actually count. You should have each of these achievements:
>
> - “Living Legend” Complete Halo CE on legendary - “Legendary Anniversary” Complete Halo 2 on legendary - “Finished the Fight” Complete Halo 3 on legendary - “The Legend of 117” Complete Halo 4 on legendary - Once you figure out which game is incomplete you need to look through individual game achievements. Here’s where you might have some issues figuring out where you got screwed out of an achievement, depending on which game you’re missing:
>
> - Halo CE: There are only achievements for beating each level, not any specific difficulty. So if you have only played on Legendary you’re in luck! Just figure out which level you’re missing and replay it. If you’re like me and already beat the game on Heroic or something, you probably have all those achievements anyway, and you’re unfortunately going to have to just play through the game again until you get the achievement. However, really look through all of them because there are some special “complete on legendary” achievements such as “Walk it off” which you get for completing The Pillar of Autumn on Legendary without picking up a health pack, so if you have it that will rule out that level for replay. - Halo 2: Just like Halo CE there are no individual “complete level on legendary” achievements, but there are “complete the level” achievements, as well as some special “on legendary complete the level with this condition” achievements. So follow the same steps as Halo CE - Halo 3: This one sucks, there are only individual “complete the level” achievements, and no special condition achievements. If you’re missing the Halo 3 campaign achievement, but have beaten all the levels previously, you’re going to have to play through the whole thing until the achievement unlocks. - Halo 4: This is easy to figure out. There’s an individual “complete mission on legendary” achievement for every level. So just check them all to figure out what you are missing. - If you really can’t figure out what you’re missing then alternatively you can wait until Halo 5 comes out, and hope you get Helioskrill in a pack. You should get it eventually if you keep buying gold and silver packs, because they guarantee 2 permanent REQs that you haven’t unlcoked, but there are a few hundred unlocks, so it may take a long time.

see above links in original post for reasons why you wasted ur time. I don’t mean that in a mean way, just sayin if u’d went 2 the links you wouldn’t have posted that list. I have achievements for finishing missions on legendary and doing special things, but none of the individual mission specific Halo CEA achievements will unlock, and I do mean none of them. it shows mission complete for all missions, but will not register for the achievement.

my achievements for Halo MCC:
DERK 91 Halo MCCupdate since i got the achievements this link no longer helps

If your going for the Helioskrill. I’m pretty sure I read on one of these forums that it is also unlocked via a REQ card, but with that you should be getting what you worked for which is that armor day one as well as your achievements. I think the MCC is just one big bug so this shouldn’t surprise you but its still bs

I just did Pillar of Autumn legendary and it did not read a completed mission for the acievement. It also did not count for the Before and After achievement.

I had a similar problem, I’m gonna have to redo all of halo 2 in legendary again… Kill me now

Check the level completion stats here on Waypoint. If one level is not registered as completed on Legendary - replay it.

I don’t want to sound like -Yoink-, but… Dude! Ya don’t think I haven’t already done that! I have checked everything! I have tried every possible fix to no avail. I’ve been dealing with this issue since MCC came out! I’m just so tired of doing this, everyday I sign on hoping it’ll be fixed. For a whole year I’ve done this and I just want what I have worked so hard to try and achieve.

It finally unlocked pillar of autumn. Maybe there’s hope?

Nothing

I unlocked all the legendary achievements I demand my damn armor I earned.

Have the same problem, Just finished CE on legendary, says it on the mission select screen that every mission is complete, but the in career only 1/10 missions are done.

Well it finally unlocked all the achievements for me. After I posted about going through pillar of autumn again and not getting it, suddenly the game started reading me completing missions as I completed them. It took another 8 hours or so to finish the CE campaign for the last time. I now have all my achievements. Never should of taken this long for the game to work properly.

My only advice to try to get it to work is to turn on time/score and turn off all skulls that’s how i ran. It just finally worked. I think you’ll b ok if u leave grunt funeral/birthday on. It does make it easier.

Hey 343 I’m a little fed up with not getting the legend achievement. The mission requiem keeps glitching even though I finished it twice on legendary finishing it skipping the cut scene or watching the cut scene, on my mcc it shows all campaigns co-op or solo I have finished the entire thing all campaigns including odst on legendary and I dont know what to do. I feel like I wasted my time for nothing to the point I’m gonna give up on halo, but hope 343 you read this and fix my problem and give me they achievement and armor if there’s a different way I can send the photos… Because my phones drive is messed up so if there’s like a fb messaging 343 studio’s the message? But that’s they only way but if you can fix the glitch that’d be great.

Same thing is happening to me but i am not getting any help at all…
