The investigetion continues! Where's Adam? And who's the killer? Check our walkthrough for Observer:
Leave flat 210. Following the murderer is fortunately not a very complicated process, as he was injured and has consequently left numerous bloodstains behind. When you are in the corridor, start looking around for them. The Bio Vision mode can help you with locating them, although using it and scanning each pool of blood is not a mandatory step. It is important that you do not rush this process, in order to avoid losing the tracks and having to return to the vicinity of flat 210 to begin the journey all over again.
During the journey you will experience hallucinations, but initially they will change nothing and you will still have to find consecutive blood marks. You must ultimately reach the closed door and try hacking the keypad next to it with the intention of discovering the code you need in order to gain access. Unfortunately, you will only learn about the first two digits of the combination (in our case it was 20). After a new scene starts, begin exploring the area and reach the room in the nightclub visible in picture 1, where you can press a small button. As a result of this action, a neon will turn on and the two missing digits of the combination will appear in front of you. Return to the keypad and enter the code 2069 (picture 2).
Go on and continue following the bloodstains until you reach one of the apartments and you will be able to interact with the intercom. Get ready, because just after the conversation with the tenant will be over, the killer will appear and if you do not manage to escape from him, you will lead to Lazarski's death. Begin your escape and do not stop until a new hallucination starts, this time taking you to a forest.
The main character is still in the apartment block. The forest is only a highly advanced hologram, and you will be consolidated in this belief by the waves which will bend at regular intervals, making it possible to see the distribution of rooms and corridors in your current location for a short time. Your task is to reach the green boxes, similar to the ones shown in the picture above. Once you have located each of them you will need to pull them out, since they are in reality holo-chips. Locating and pulling out all three devices will allow you to "return" to the apartment block.
You can listen to new messages left on the tape recorders or immediately resume the process of locating the killer's blood marks. The tracks lead to the attic, so get to the nearest staircase and head up the stairs. Once you reach the top floor, open the door to the attic that you previously found closed.
VERY IMPORTANT NOTE - After you enter the attic and the next scenes will play out, you will no longer be able to return to the main part of the apartment block. If you have any unfinished business to deal with in the area of ??the block, (e.g., concluding optional investigations or examining all flats) take care of it first.
Once you have found yourself in the attic, continue along a very linear path. This will lead you to a flap in the floor, which you have to raise and then jump into the large opening. At exactly the same time the assassin will attack you, but this is a directed scene where you will not have any influence over the events.
