The Cold Snap update has several new quests in ARC Raiders, and the Deciphering the Data mission will require you to visit two different locations.
Thankfully, this quest is relatively simple, and you can complete all the tasks in the Spaceport map. This guide lists all the steps for you to complete the quest and its tasks.
ARC Raiders Deciphering the Data quest walkthrough
The Deciphering the Data quest can be broken down into the following parts.
- Use the Magnetic Decryptor in the Fuel Control building
- Reach the Arrival Building in Spaceport
- Use the Magnetic Decryptor on the top floor of the Arrival Building
The first task requires us to head to the Fuel Control building on Spaceport. Located in the northern part of the map, I have marked its location so that you can find it easily. Approach the building from the west.

Head inside, travel straight, and you’ll come across a green machine. Interact with the machine when prompted, and you’ll complete the first task. The machine isn’t hard to find, and completing this part of the quest is relatively easy.

Then, head to the Arrival building on the eastern part of the map. Approach the building from the eastern side and take the stairs till you reach the second floor.

Enter the building, and keep heading northwest on the second floor. You’ll eventually come across a bunch of electrical devices. Get close to the devices, and you’ll have a quest marker appear on one of them. Interact with the highlighted device to decrypt the data. This will complete the final task and the Decrypting the Data quest.

There are plenty of other quests to complete in the Cold Snap update, and we have dedicated guides for all.
