How do you get it? Scan literally every single enemy that you come across throughout the campaign, or just scan at least one of each type of enemy and all the bosses? Because I'm pretty sure I did the latter, but didn't complete the mission.
God knows what I missed. I scanned almost everything I saw :S
You know how some bosses let you scan them say four or five times before their scan outline turns white and you can't scan them anymore, do you have to do that on each type of enemy or boss, or is just one scan of it enough?
i hope you dont have to scan it more than once, im trying to do that mission and only recently noticed you can scan more than once, but i have a feeling you have to keep scanning till it turns white :(
