Here I am playing on the hardest setting and trying to get the pacifist achievement also. I just finished the "Black Hawk Down" scene when you arrive back in Hengsha. After 5 MILLION retries I finally downed all the enemies non-lethally, and got the robot without any "collateral damage" or accidental kills. But...there's one guy who shoots a barrel that he's standing next to right at the beginning of my save.
Here's the question:
Does that guy count against my no kill record? Am I disqualified from the Pacifist achievement because of something the computer did? Would it be "safer" to just reload from an earlier point?
