Directive 8020 Probe Serial Number Guide: How to Unlock the Code (2026)

The serial number required to bypass the security lock on the probe in Directive 8020, developed by Supermassive Games, is 2540. To successfully unlock the device during episode 7, players must locate three separate fragments of the code scattered around the immediate environment on the planet Tau Ceti f. This puzzle is a mandatory step for players looking to send either a distress signal or a warning to Earth.

If you are currently stuck at this sequence, follow these steps to retrieve the code:

1. Locate the first screen next to the input panel to identify the final two digits (40).
2. Find the second screen at the back of the probe near the replacement chip to identify the first digit (2).
3. Search behind the rocks to the right of the probe to find the third screen and the missing digit (5).
4. Replace the overloaded chip with the unit found at the rear of the probe.
5. Input the full sequence 2540 into the interface to proceed.

How to find the probe serial number in Directive 8020

In our coverage at In Game News, we have observed that players often find themselves stalled during the seventh episode of Directive 8020. The probe puzzle is designed to test your observational skills rather than your ability to solve complex logic gates. Because the storm on Tau Ceti f has caused corruption within the probe systems, the serial number is not displayed in one single location. Instead, the game prompts you to piece together the four-digit sequence by investigating the surrounding area.

The primary challenge stems from the fact that the screens displaying the serial number are damaged. You cannot simply read the full code from a single terminal. You must visit three distinct locations around the probe to collect the necessary data. For more tips on navigating these tense sequences, you can check out our guides and walkthroughs.

Step 1: Identifying the final digits

The first step in our Directive 8020 probe puzzle solution guide is to examine the screen positioned directly next to the input panel. This terminal is the most accessible, as it is located right where you perform the interaction to enter the code. Upon inspection, this screen displays the digits '40'. These represent the final two numbers of the four-digit serial number sequence.

Step 2: Locating the first digit

Once you have noted the '40', you should move to the rear of the probe. This area is also where you must retrieve the replacement chip necessary to fix the device. Look for the second serial number screen in this vicinity. This specific screen is partially obscured but clearly displays the number '2' at the start of the sequence. At this point, you have identified the first digit and the last two digits, leaving only the second position in the sequence unknown.

Step 3: Finding the hidden third screen

The final piece of the puzzle requires a bit of exploration. Head toward the rock formations situated to the right of the probe. Tucked behind these rocks, you will find a third screen that has managed to survive the environmental corruption. This terminal displays the number '5'. By combining the '2' from the back of the probe, the '5' from behind the rocks, and the '40' from the input panel, you successfully construct the full serial number: 2540.

Completing the probe interaction

With the code in hand, you must ensure the hardware is ready for the input. If you have not already done so, remove the overloaded chip from the probe and replace it with the functional unit found at the back of the device. Once the hardware is swapped, interact with the input panel to enter 2540. Successfully completing this task allows you to proceed with the narrative, choosing whether to broadcast a distress signal for rescue or a critical warning to Earth. This moment represents a significant turning point in the game, and having the correct code ensures you can move forward without further delay.
