Doom the circle is complete bug fix GLITCHED This trophy is possibly, but not confirmed to be glitched in that previously-unlocked Runes may ‘unstick’ themselves and become relocked. In that case, you will have to recomplete their requirements using Mission Select. Do this after your first playthrough to avoid other collectibles glitching. Each rune is earned by a trial, essentially a short challenge in a different map to the main area. You have to find each rune before attempting the trial.
