After throwing a little tantrum dying over and over, trying to defend the missiles at the end of Mass Effect 3 on insanity, I finally did it. But for some reason I didn't get the 'insanity' achievement. I'm curious to know if anyone else has had this problem?
I skipped past the majority of side missions, since in-turn they're side missions, and the game only asks that I complete the game on insanity without changing the difficulty. For those that have the achievement, did you completely all the primary and secondary missions? The 'Insanity' and 'Hijack' achievements are the only two left on my list.
