Neon Nights

SM00: Neon Nights is a side mission in Deus Ex: Mankind Divided. It is available for Adam Jensen during his first and second visits to Prague, and can be completed during either visit to Prague. Completing this mission unlocks an achievement/trophy of the same name.

Starting the Mission
There are several ways to start the mission:
 * Go down the stairs from Jensen's apartment and look for a vent. Follow through the vent to a restricted area. There will be two NPCs, one of them hostile. You can either take him down, or wait until he is done talking and moves out of sight. In the kitchen is a level 3 computer covered by a box. Hack the computer or use the password DobraNoc. Reading the emails will start the mission.
 * Enter apartment 202 at 33 Hlavní (the building near Task Force 29 HQ - this is also where Jim Miller lives). There are two pocket secretaries in this apartment and reading one of them will start the mission.
 * Find a small courtyard near Jensen's apartment with a restricted area walled off and guarded by a single bodyguard. Check out the safe near the wall and read the pocket secretary.
 * Eavesdrop on various drug addicts to get a Point of Interest (POI) to start the quest.

Behind Our Backs
If you did the first option of starting the mission, make your way now to the 2nd option (202 at 33 Hlavní apartment). This apartment has a security feature that detects you are a stranger and will start counting down when you step inside so quickly access the terminal inside via hacking or using a multi-tool. It will automatically update its information so it recognizes you as the apartment owner so you can now move around freely. Also, if you do not have the punch through wall aug and EMP shielding, go ahead and hire the cleaning service on the terminal (under House A.I., then environment). To finish this area, find and read one of the pocket secretaries to learn the location of the Rave.

The Rave
You will find the entrance in a courtyard that requires a neon keycard. If you have the earlier mentioned augs, go over to where the trash containers are and move them aside to punch through the vent and enter the party through the electrified opening. If you do not have the necessary augs, run back to 202 Hlavní, which is now spotless if you hired the cleaning service. You will find a neon keycard by interacting with the swan towel on the bed. If you did not hire them before going to the courtyard, you can take the subway to another station and return and it should be there.

Whichever way you got into the party, make your way to the locked room and get inside. You will find a dead augmented raver with a pocket secretary warning him, too late, of the dangers of using neon as an Aug and the location of the neon suppliers.

The Door of Perception
Now head to Libuse Apartments, room 84. It has a giant rainbow swan on its door, making it easy to spot. There are multiple ways into this apartment, either through vents or by hacking the wall panel. If you entered through the door, go into the kitchen area and activate the spray bottle to reveal a secret room with a safe. If you used the vents to get in, you will end up in this room. Unlock the safe and read the pocket secretary to learn the lab’s location.

Where All the Color Comes From
Head into the sewers near Zelen Apartments and towards the marker. The code you got off the pocket secretary can be used on the gated door, but you will notice it is guarded by a turret with an almost 360 degree sweep. If you do not have remote hacking but have the EMP shielding, you can instead jump onto the electrified ledge and hack the door up there. You cannot turn off the electricity as it is needed to power the panel. If you go through the main door, there is a level 3 security terminal behind the turret you can use to stop it (it is in the turret’s small blind spot so you can access it without it spotting you).

Whichever way you enter, now head up the stairs and use the same code to open the metal paneling. There is also a path up on the right side if you can get up there and move the trash container. Take out the guards or sneak around on the upper floor, just keep in mind the sniper for the latter option. If you do not want anyone becoming alarmed, take him out in the small room he goes in on his patrol. This small room also has a level 3 security terminal that will allow you to turn off the area’s cameras and laser grid in the lab, making it a lot easier to sneak around.

Enter the chemist’s room, where the chemicals to make neon are kept. You have a few different options here to complete the mission. Once you have chosen your path and emptied the tanks, the mission will complete.
 * You can sneak into the locked area using either remote hacking or the klipspringer aug to get in.  If you did not already turn off the laser grid, the panel up there will let you.  Now drop into the lower area where the tanks are and insert a biocell in each white generator in the center (2 are needed) allowing you to hack the now powered panel in the middle and empty the tanks, finishing the mission.
 * You can destroy the tanks which will complete the objective but it's recommended you do it from a distance or get the implanted rebreather augmentation as doing this causes gas to leak from the tanks.
 * Confront the chemist directly. If you get close enough to her, you will automatically enter a conversation, which can go a number of ways:
 * Using dismantle then threaten, or warn then moralize, will make her sound the alarm
 * Using dismantle then reason, or warn then relent, will not make her sound the alarm, but she will not help you either.
 * Using warn then confront will make her sabotage it herself
 * If you have the CASIE aug, you can do persuade (under dismantle), then reverse psychology twice. You can then use "expert" which will get her to sabotage it herself, or "help" and she will give you the codes and biocells to do it yourself.

Trivia

 * The objective name "The Door of Perception" is likely a reference to 's 1954 essay  that details his experiences when taking mescaline.
