I’ve tried everything but it still wont unlock. i’m hoping 343 will see this and help not just me but many others
What exactly have you tried? Basic question, but have you connected to Live since completing the campaign? As far as I know, the only buggy achievement in Halo 5 is Warlord and the rest work as intended.
I have the same issue been that way for months, the legendary campaign completion and lone wolf achievement never unlock for me, tried replaying the campaign again on legendary and didn’t skip any cut scenes and nothing
