    It's not that hard. Just don't attack any human (don't even fire one shot at them, don't stun them either).

    You can let androids and the alien attack humans (with, for example, a noisemaker).

    You can also run past humans if they found you. Make sure you're on full health. But they usually miss a lot (and attract the alien instead laugh).

    Here's a guide I put together to help with this achievement, I played through on Nightmare although i'd recommend going through on an easier difficulty, the strategies in the video will work just the same. Hopefully the guide helps some of you out.
