Pacifist (Mankind Divided achievement)

Pacifist is an achievement/trophy in Deus Ex: Mankind Divided. To be awarded it, you must complete the game without killing a single person, including the final boss of the game.

Requirements
The entire game must be completed without killing a single person. This includes the final boss fight, meaning that the final boss must be defeated without killing him. Killing a person using lethal ammunition or a lethal takedown will void the achievement. However, incapacitating enemies using non-lethal ammunition and augmentations, such as P.E.P.S and the Typhoon Explosive System (if set to non-lethal), is permitted.

Permitted actions
The following actions do not count as "killing" for purposes of this achievement:
 * Hacking a turret or robot and setting it to friendly fire will not void the achievement, even if enemies die by the turret or robot's friendly fire.
 * Causing death by turning on an electric floor that electrocutes a person will not void the achievement.
 * Causing death by destroying an object, such as a robot or car (whose explosion results in casualties), will not void the achievement.
 * Deaths caused by NPCs, such as police, do not void the achievement.

Tips

 * A stealthy approach that avoids combat makes the achievement more easily obtainable. This achievement and Foxiest of the Hounds work well together as they benefit from a stealth-oriented play style. Some augmentations that make stealth easier are the Glass-Shield Cloaking System as you can bypass enemies without being seen, and Smart Vision which highlights the locations of enemies.
 * When you decide to take down an enemy rather than just avoid them, you can check that they have not been accidentally killed by inspecting the HUD symbol over their body. If they are just knocked out, it will display a yellow "Zzz", but if they were killed it will show a red skull.
 * If inspecting from a distance, for example using a scoped weapon, unconscious/sleeping enemies have their eyes closed while dead ones have their eyes open.
 * This achievement cannot be received at the same time as Laputan Machine, as it requires you to kill Viktor Marchenko. If you want to get both achievements in the same playthrough, save before the boss fight, activate the killswitch, and then reload.
