Dying Light is one of the more unique concepts within gaming that's been released, and Techland, the studio behind the series has released the long awaited sequel to the original game.

Over the course of some missions, you're going to come across some riddles, including one of the first side-quests, The First Biomarker.

Dying Light 2: The First Biomarker Safe Code

The First Bio Marker is a quest given to you early on within Dying Light 2, and its essentially a riddle that you're going to have to solve in order to unlock the safe and collect the Inhibitor.

Within your in-game inventory is the riddle itself and it reads as follows.

"What becomes smaller when you turn it upside down. An odd number, take away a letter and it becomes even. A little girl goes to the store and buys one dozen eggs, all but three eggs break, how many eggs are left unbroken."

The code for cracking this safe will be 9 7 3!
