In order to get this achievement, you need to complete the campaign without killing any human. But this one is tricky because, it should have said "complete the game without using ANY weapon against any human". This includes the stun gun. Indeed, if you use it, you will miss the achievement because it seems to be lethal. It is pretty unfair since it is usually a incapacitated weapon but not in this game.
Missions 12 and 13 are quite difficult because you will run into humans and androids at the same time. So try to use noisemaker to attract androids so they can help you getting rid of humans. Missions 15 and 16 are more difficult because this time humans are equipped with special tactical suit and weapon (mainly shotgun). There are less androids but this time aliens are back. Same strategy here. It is highly recommended to play in easy mode to get this achievement more easily, as hard mode is rather tough, especially if you want to get the One Shot achievement at the same time.
