I just beat halo 2 anniversary on heroic. I did not get the achievement for beating it on heroic or or normal . I checked missions and every one says i beat it on heroic but when i go to career and check achievement progress it says only 12/13 completed. Anybody know a fix to this. Im pretty upset over it.
Hi there! According to your Waypoint stats you’ll need to complete quarantine zone again!
I have been stuck on 10/13 for a week now. Waypoint tells me I need to do the last three but I’ve done the last three countless times since to try and get it to update. Nothing works so I guess we sit tight until they fix it and hopefully they will pop automatically.
Ive done like 4 on legendary on halo 2 ann and waypoints got nothing for me.
I can understand maybe not getting legendary credit for using scarab/bandanna but can i at least get the level completion achievements regardless 
kinda upsetting
The DDOS attack or whatever it was that XBL went through yesterday prevented some cheevos to unlock immediately. I “unlocked” three yesterday that still hadn’t didn’t registered before I turned in last night. I checked again this morning and they were unlocked. It’s not as satisfying as seeing that icon pop-up and hearing that bleep-bloop but still…
So, check your stats today.
Sadly the maps i did had Scarab / Bandanna on so chances are i won’t get credit.
Which to be honest is bull… because CE allows Bandanna
IIRC CEA doens’t allow bandana either for scoring/time/level completion cheevos. But yeah, if you use them on H2A you get diddly. As far as the game is concerned they’re cheat/god mode skulls.
well at least can still do collectibles, easter eggs and level related achievements , just not progression related ones 
I Just tested with only scarab on and still didnt get nothing and people are saying you can
