How to unlock the Clean Sweep achievement in Deus Ex: Mankind Divided - Definitive Guide
Utilise cloaking (level 1 or 2 should suffice) and use the stun gun when needed.
(Missable!)
Like the Pacifist trophy in Mankind Divided, you must complete the game without killing anyone. The game starts you off with a stun gun so that's your go-to weapon. As the DLC doesn't feature a lot of guards, you'll hardly use it anyway, relying more on stealth or melee. If done correctly the trophy will pop when the end-game cutscene rolls.
This achievement will require that you complete the entire add-on without ever having killed a single individual. Fortunately, System Rift is pretty short and there aren't too many instances where you'll be in a tight spot with hostiles who are in your way. There are a number of gadgets and equipment items to deal with hostiles non-lethally (Stun Gun, EMP Grenade, Gas Grenade, etc.), as well as the traditional non-lethal melee takedown, but you shouldn't have to rely on any of that.
Much like the base game, avoiding contact altogether and sneaking past enemies is much easier. If you do choose to knock out enemies, just remember that a "ZZZ" icon means they're unconscious and the red "Skull" icon means they're dead. This achievement will unlock during the final cutscene with Pritchard provided you did not kill any enemies during the narrative.
After completing the DLC, I started the game again and made my way to the bank through Slow.
You can get into the bank in at least 2 ways (I didn’t find any more, but I didn’t try too hard): through the lobby employee, calling him by the nickname that ShadowChild reports, or from the left side of the bank, going up the stairs and walking around the guard from behind. I don’t know what the author above means by the third method, but perhaps he confused it with opening the door on the second floor inside the bank with the help of Slow, for which they give a separate trophy. However, obtaining it does not depend on the method of entering the bank.
