Directive 8020, developed by Supermassive Games, throws you into a tense sci-fi horror experience where locked doors and coded puzzles stand between you and the full story. There are six key codes hidden across the game, and while the clues are always nearby, tracking them down mid-panic is not always easy. So here is every Directive 8020 code you need, along with exactly where each one comes from.
All Directive 8020 Key Codes Overview
| Location | Code |
| Locker Room | 13576 |
| Carter’s PC | 0828 |
| Food Storage Room | 0402 |
| Diazepam Synthesis | 168 |
| Anomaly Log | 3196 |
| Probe Serial Number | 2540 |
Worth noting: most of these codes unlock optional Secrets rather than story-critical doors. However, the Diazepam code is required to progress through a specific part of the story, so you will not want to skip that one.
Locker Room Code: 13576
The Locker Room code is the first one you encounter in the game, and it is actually the trickiest to locate if you are exploring naturally.
Here is how to find it:
- Leave the Locker Room and head back to the Atrium
- Climb the stairs to reach the top level
- Use your Utility Strap to open the shutter directly across from you
- Look through the window and use your Utility Strap again to unlock the door, then head inside
- Inside, you will find a security camera showing the Locker Room code
Locker Room key code: 13576
Carter’s PC Code: 0828
This one is a clever little puzzle built around a personal detail belonging to one of the characters. On Carter’s PC monitor, you will spot a sticky note with the name “Luna” written alongside a drawing of a party hat.
Luna is the name of Carter’s daughter. Head back into the previous room and find the calendar on the wall. Luna’s birthday falls on 28th August, which in the US date format reads as 08/28, giving you your four-digit code.
Carter’s PC key code: 0828
Food Storage Room Code: 0402
You come across the Food Storage Room code during the Search quest, specifically inside the Mess Hall. However, you need to unlock a hidden room first before the code reveals itself.
Steps to find it:
- Locate the door in one of the corners of the Mess Hall
- Use your Wedge tool to break it open (it is the only door in the Mess Hall that the Wedge works on)
- Head inside and explore, then check the door frame as you leave
- A sticky note on the wall clearly shows the Food Storage Room code
Food Storage Room key code: 0402
Diazepam Synthesis Code: 168
This one works a little differently from the others. Rather than a traditional locked door, this is a chemical synthesis puzzle that appears on a key code screen with three digits. You need to combine three specific chemicals found in a nearby cabinet, each labelled with a number.
The three chemicals and their corresponding numbers are:
| Chemical | Number |
| Chloroacetyl Chloride | 1 |
| Ammonia | 6 |
| Dimethyl Sulphate | 8 |
Combining those three numbers in order gives you the code.
Diazepam key code: 168
Anomaly Log Code: 3196
You encounter this code while playing as Cernan, during the section where you are searching for the rest of the crew. There is a locked screen inside Bridge Ops that needs a numerical code to open.
To find the solution:
- Walk through the door to the right of the screen in Bridge Ops
- Follow the hallway all the way to the cockpit
- Find the sticky note on the control panel, which reads: “Anomaly Log code. CAIF”
- Back at the keypad, translate those letters into their alphabetical positions: C=3, A=1, I=9, F=6
Anomaly Log key code: 3196
Probe Serial Number Code: 2540
This code appears later in the game, during Episode 7, and catches a lot of players off guard because the solution splits across two sides of the same object.
Here is how to piece it together:
- Examine the front of the Probe to find a clue showing the number starts with 2
- Flip to the back of the Probe to find a clue showing the number ends with 40
- The missing middle digit is 5, giving you the complete serial number
Probe Serial Number key code: 2540
This one unlocks a Secret rather than a story-critical door, but it is one of the more satisfying puzzles in the game precisely because the answer requires you to physically examine both sides of an object. Players who rush past the Probe without flipping it over tend to be the ones searching for this code later.
Quick Tips for Finding Directive 8020 Codes
If you prefer to hunt codes down yourself rather than look them up, keep these pointers in mind:
- Sticky notes are your best friend. Most codes are written nearby on notes or calendars, so slow down and read everything in the environment
- The Utility Strap and Wedge tool unlock access to several code clue locations, so always try them on doors before moving on
- Most codes unlock Secrets, not mandatory story content, so missing one will not block your progress (except the Diazepam code)
- Letter-to-number ciphers follow simple A=1, B=2 logic, so if you ever find letters on a keypad, just count them out
- Always examine objects from multiple angles, as the Probe puzzle proves that clues can hide on both sides of the same item
Directive 8020 released on 12 May 2026 and is developed by Supermassive Games, the studio behind the broader Dark Pictures Anthology series. Now that you have every code sorted, you can focus on what the game does best: making every decision feel genuinely dangerous.
