I got this on Mission 6. There will be a part where you have to re-activate an evacuation procedure in order to escape. During this part you'll unwittingly activate an Android.
After you've activated the evacuation procedure, shoot the Android a few times to gain his attention. After that, all you have to do is use your Stun Rod (which you probably got in this chapter) to stun him as he walks towards you. I teased him a bit so I was sure he was in "combat" mode.
Once he's stunned, run out of the room and get as far away as you can from him. I just completed the mission normally. After this he should eventually call off his search and you'll get the achievement.
If you haven't already, you'll also get the "Stunned" achievement with this method too.
