The code for the safe in the quest The First Biomarker in Dying Light 2 Stay Human

In Dying Light 2 Stay Human, there are many additional activities, including side quests. While wandering the city, you will meet a former GRE scientist who will tell you about a special biomarker and assign you the task of finding the device. In this guide, we will tell you where to find the scientist, how to get into Dr. Katsumi's office, and solve the safe puzzle in the quest «The First Biomarker».

You can activate the quest as soon as the game allows you to explore the open world. You need to find the GRE scientist who claims to be the creator of the first biomarker. He is located near a shop between the «Trinity» and «Houndfield» territories.

During the conversation, the man will tell you about the first biomarker, which not only suppressed the virus in the blood but also enhanced some of the body's abilities. This biomarker is now hidden in Dr. Katsumi's safe, the former head of GRE. Her office is located on the middle level in St. Joseph's Hospital. You have already visited this hospital before, so getting there should not be difficult.

At a low character level, the only way to get into the building is through a bus in the wall. Go up to the third floor and find the broken window, which you can use to climb into the office.

If you did not remember McGregor's hints, you can open the «Collections» menu and read the letter in the «Memorable Souvenirs» files — «Riddle Note from Dr. Katsumi».

Correct answers:

The safe code: 973.

By opening the safe, you will find the very «first biomarker», which will temporarily increase your character's stats. In any case, the biomarker needs to be brought back to McGregor to receive your well-deserved reward.
