Exploring a closed apartment
This is one of the side quests that you can complete in the Observer. You can open it after completing the initial part of the game, that is, after investigating the crime scene in apartment 007. This will unlock access to most of the apartment building.
For this task, you must go to the first floor of the building and get to apartment 113 (use the maps on the walls that lead directly to it). Interact with the intercom to talk to a girl named Paulina. She gives you the code 1074, which will lead to the addition of the case to the main character's journal.
You don't have to go far to find a place where you can use Pauline's code - the panel is at the door to the neighboring apartment 114. Interact with her and enter the code 1074.
In the first room you will find a painting (secret) and some objects to scan: a holographic frame and an inhaler (use biological vision). Move the curtain and go to the next room. The most important discovery is what is shown in the picture above - a woman connected to a complex machine. Scan the device and the woman. Also nearby you will find syringes with synchrosin, a computer (you can view its disk) and a syringe with substance 45F.
Hack the Mind of Pieta Sagan
Switch to electromagnetic vision and examine the woman's head. Examination will reveal the implant shown in the picture above, which will help identify the woman. That's not all, as you can also press the button indicated in the game to hack into Pieta Sagan's mind and go through one of her nightmares.
You start at a location that resembles apartment 114, but soon you will find yourself in an unknown hospital. In the next scene, there will be a hill that you must climb. Keep pressing the navigation key up and hide behind the objects you pass by to resist the wind. When you get to the fence, use the hole on the left.
Once you reach the very top, you have to follow a few simple steps. First press the button shown in the picture, and then take the hanging cable.
You have to carry the cable to the left (during the intervals between gusts of wind) and insert it into the socket shown in Figure 1. Finally, interact with the slide shown in Figure 2 and pull it as far to the right as possible. This will open up the upper passage, and you can approach Pieta to talk to her. The dialogue options do not matter, since the decision on how you complete the case will only be after leaving the nightmare and returning to the real world.
The case can be done in two ways. The first is a system reboot that ends the connection between minds, resulting in Pieta's death. The second option is to restore the connection between the minds of Pieta and Paulina.
In both cases, you must interact with the computer in the room, go to the programs tab and select the Cephalus_7 .34 program (picture above). The left square means option 1, and the right one means option. The case will end regardless of your decision.
