Deus Ex: Mankind Divided Trophy/Achievement Guide - Neon Nights
This achievement can be earned from the moment you can roam the streets with Jensen in mission 2. To start it you must hack or enter the password 'Dobranoc' into the PC in an apartment two floors below Jensen's apartment. After reading all the emails, you will then have to catch a train to Palisade.
Once arriving at Palisade head towards the apartment building with the big '33' on the side of it (take the stairs to the left when leaving the station and it's right there) and head upstairs. You won't be able to get inside as the apartment is locked so you will need to climb around the side and into the apartment next door. Open up the vent found in this room and crawl through it to the other side. Once inside the apartment quickly rush to the terminal and hack it, this will allow you to gain control of the House AI which will allow you to call for a cleaner to come to the apartment. At the same time read the emails and collect the Pocket Sec's around the house to get the next objective, go to the Rave.
However, you must first travel to another area and come back to the apartment to find it clean with a towel swan made up on the bed containing a Neon Pass which will let you get into the RAVE. Head to the RAVE and find the dead body behind a locked door and take his pocket sec.
Now head to the apartment building the waypoint takes you and look for the rainbow swan on the door. Hack your way inside and interact with the soap bottle on the side bench to find the hidden door. Walk inside and open the safe for the next pocket sec and head to Jensen's apartment complex again.
Now go down the manhole beside the building until you find a locked gate, the password for both doors is 0311. Hang a left when in the room with all the enemies and head towards the security room to turn the cameras and lasers off. Keep to the left and you will drop into a room with the chemist.
Now you must have the Social Enhancement Augment to get the Persuade option then choose the Reverse Psychology Option and then the Help me Sabotage option. She will give you two biocells which you have to inject into the pods and then empty the containers and the achievement/trophy will unlock.
