hi,
I was finished Halo 2 on MCC on heroic difficult, but some achievements wasn’t unlocked.
list of achievement : Regret, Sacred Icon, Quarantine Zone, Gravemind, Uprising, High Charity, Great journey, warrior, Hero and Needs more whammy Bar.
I was finished some levels several times but achievements never unlocked. I don’t understand why because I am online
PLEASE HELP
