Safe on Electrofield in Stalker 2: how to open?

The Exclusion Zone from Stalker 2 is full of mysteries and secrets. Most of them are related to caches and hiding places, but not all of them are as complex as the safe on Electrofield, located in the southeast of the Garbage. Getting to the building itself is not easy due to the many electrical anomalies that cause damage. But the real problem is how to unlock the safe itself.

To open it, you need a code, but there are no indications of where exactly to look for it nearby.

How to open the safe on Electrofield in Stalker 2

The code for the safe on Electrofield is 1708. The safe itself is on the second floor of the only building and opens through the code panel on the wall on the left. Enter the code and take the reward from the backpack hidden inside the cabinet.

But why the code 1708? How to find it? To do this, you need to leave the building, go around it and climb the stairs to the roof. Go forward, without turning anywhere, and you will find a flash drive on the roof railing. After picking it up, you will learn about the cache itself. Its icon will appear on the map. After opening the map, hover the cursor over the cache to see the description. At the end of it there are four words. Imagine what the listed objects look like and what numbers they resemble.

• Stick = 1
• Cobra = 7
• Window = 0
• Infinity = 8
