This section will describe how to solve the murder puzzle in Get Even. You will have to deal with this task once Red becomes a playable character. This will take place during one of the memories - "J_dying_minutes -reveal". Your task will be to find out how the murder was committed.
As soon as the new memory begins, you will have to solve a puzzle. The very idea is pretty easy but the solution may not be that obvious (especially without any tips). You can obtain some hints if you look around. First, approach the hole in the right (locked) door and listen to a conversation between Jasper and a stranger. Head to the back of the room and find crime scene report. It contains information on the victim's death and the weapon.
Go back and interact with an engram. You need to recreate the murder by manipulating three interactive parts. The victim was killed by a headshot when he was standing, so select the right position (see screenshot).
Now interact with the object in the middle, and select the silencer as the murderer's weapon (see screenshot).
Focus on the last piece of the puzzle. You need to swap between suspects until you select Black. At this point the puzzle will be completed automatically, and you will progress to the next scene.
