In addition, you can upgrade your guns to level 10 (instead of the max of 5 on your first playthrough). This will allow you to be a significantly higher level (50-55ish depending on how many sidequests you did on your first run), with the resultant levelled skills. With that spoilerific revelation out of the way, I would like to provide some tips (please note this is from a soldier POV, see the bottom of the guide for details):ġ) I highly, highly recommend doing your Insanity run on a New Game+ with an imported ME3 character (your character from your initial run). The instructions for getting this achievement are, not surprisingly, putting the difficulty on Insanity right away on Earth (or from the main menu) and not changing it during the course of the game.
