I'm looking to get the Spartan armor unlock for beating all the campaign missions on legendary. Unfortunately my power went out near the end of one of the missions as I was doing it on legendary. Am I able to start at the furthest checkpoint while still on legendary, and still get the requirement for the Spartan armor? Thanks in advance.
Have you tried just "continue campaign" instead of going to mission selector? That should bring you to the last saved point that the game knows you completed, right? So theoretically wherever it puts you is the right spot to start.
if it's that far back where it's before the last rally point, then you pretty much have your answer, right? --- Lali-ho!
