a little help please

Anyways now I finally had time and beat the campaign on legendary solo yet no achievements popped up and I thought “well this sucks” but maybe it’d be the delayed pop glitch that sometimes happens to games. Three days later now and I was running through some achievements and I looked in Halo 5 for the perecent progress and it showed the heroic, legendary, and legendary solo achievements at 93%. I don’t quite understand what’s going on but I can make a video to verify my completion if necessary.

Any and all advice is greatly appreciated.

I had an issue when saving and quitting and then resuming the mission. Look at per mission achievements. It should say what mission you haven’t completed, just play it all the way through again (inconvienent, I know) but if you want the achievement it should work that way. I ended up playing all missions start to finish for this reason.

What exactly is per mission achievements? If you mean the individual ones for completeing them in general thwn I got those around the first week of the games release. Looks like I’ll be replaying every mission then since I can’t remember when I saved and quit.

Wait would I have to run through on legendary again or can i blaze through on easy to get it quicker.
