'Finish all of the missions at Level 30 on the Hard difficulty.'
So I have 100% the story mode side of things, but this accomplishment still stands at 93%
From what I can see in game, you can't see which missions you have completed on hard (or challenging for that) or am I being dumb?
Guess I could make my own check list and solo run through them all again? Just wondered if there was an easy way to do it before doing all of that.
