This section will describe how to set the code to a locked door in the hospital (playing as Red) in Get Even. You will have to deal with this task once Red becomes a playable character. You will visit the hospital during one of the memories - "Grace_Kindapping -reveal".
You will have to solve the puzzle once you reach the Transplantation ward (Transplants sign). This takes place in the room where you will observe a short scene (see screenshot).
Carefully investigate one of the right shutters. Place yourself in a way that will allow you to read the four digit code. The screenshot presents our scenario - code 4190 (many puzzles will undergo a random scenario, thus you may get a different code).
Locate the warp in the neighboring room and teleport yourself there. Approach the electronic lock and type in the code.
