Early on in the game, you'll pick up a side quest that has you tracking down what's claimed to be the very first Biomarker. The mission's main challenge is working out the code to a safe in order to get your hands on the device. In this Dying Light 2 guide, we're going to reveal the safe code solution for The First Biomarker side quest.

Dying Light 2 The First Biomarker: Safe Code Solution

Dying Light 2 The First Biomarker: Safe Code Solution Guide 2

The First Biomarker side quest can be picked up in the Trinity territory. You'll need to speak to the NPC standing outside the Trading Post on the western side of the region. He will tell you of a safe nearby containing the first Biomarker, and then gives you a set of riddles to solve in order to work out the solution to the safe. You'll then be directed to a building just north, which is where the safe is.

After reaching the marker on your map after accepting the side quest, open up your Collectables tab on the menu screen and read the Safe Code — A Note from Dr. Katsumi containing a riddle Artifact Collectable. There are three different riddles to solve, each revealing a number that makes up the safe code.

The first riddle is as follows:

  • What becomes smaller when you turn it upside down?

The number 9 can be turned upside down to make a 6. Therefore, the first number in the safe code is 9.

The second riddle is as follows:

  • An odd number — take away a letter and it becomes even.

If you remove the S from the word seven, it is literally spelt "even". Therefore, the second number in the safe code is 7.

The third riddle is as follows:

  • A little girl goes to the store and buys one dozen eggs. As she is going home, all but three eggs break. How many eggs are left unbroken?

It's easy to overthink this one because the riddle has already given you the answer. "All but three eggs" have been broken. Three eggs are left unbroken. Therefore, the third number in the safe code is 3.

And there's our safe code: 973.

Input the three digits into the safe and you'll open it to find the Biomarker. Defeat the three zombies that spawn and return to the quest giver nearby to complete the side mission.
