Finding every single code in Stellar Blade is a total nightmare if you're trying to do it solo. Honestly, it’s one of those things where you’re just running around a desolate wasteland, squinting at a tiny robot or a corpse, hoping it has that one specific string of Greek letters you need. You've probably already hit a wall with a door or a chest that looks important but won't budge. Basically, the game loves to hide its best loot—Nano Suits, Exospines, and those precious upgrade materials—behind these digital locks.
The thing is, Stellar Blade all passcodes aren't just random numbers. They're usually tied to the environment, tucked away on a Legionnaire who didn't make it or inside a data bank you might’ve sprinted past while fighting a Naytiba. Some are easy. Others? They require you to solve actual puzzles or finish side quests before they even appear.
Let's break down where these things are hidden so you can stop staring at locked screens and start actually playing.
Eidos 7: The First Hurdles
You’re barely into the game and already the world is throwing locks at you. Most players get stuck at the "Ground 317" door. It’s annoying. You see the door, you want to go through, but the game forces you to take the long way around the plaza.
- Ground 317 Door: The code is ααυθβθ. You’ll find it on a dead soldier under a "Barker Drugs" sign. Don't try to shortcut it; just loop around the plaza.
- Pharmacy Chest: This one is in Silent Street. You need the code from a body on a balcony nearby. Once you have it, go down the ladder from the campsite to the pharmacy.
- Bar 99: This is a weird one. You can't even get the code until much later. You have to wait until you can access the "Legion's Secret Stash" quest from the Xion bulletin board. The code is 1228.
Most people try to open Bar 99 as soon as they see it. Don't. You're just wasting time. It’s a late-game reward disguised as an early-game obstacle.
The Wasteland and the Recruit Passcode Specialist Quest
The Wasteland is huge, and it’s where the "Recruit Passcode Specialist" quest lives. This is arguably the most famous puzzle in the game because it involves finding six different shrines scattered across the map (and even in Matrix 11 and the Great Desert).
The Shipwreck Container
This is the big prize in the Southwestern Wasteland. Inside a derelict ship, there's a container that requires six Greek symbols. You get these by visiting "Follower Shrines."
The final code sequence is βθαλασ (Beta, Theta, Alpha, Lambda, Sigma, Zeta).
If you're looking for the chapters:
- Chapter 1: Matrix 11 (Hideout second floor).
- Chapter 2: Great Desert (North ruins).
- Chapter 3: Great Desert (South ruins).
- Chapter 4: Great Desert (Inside the Hypertube area).
- Chapter 5: Wasteland (Western canyon).
- Chapter 6: Wasteland (Eastern canyon).
It's a lot of legwork. But the outfit you get? Totally worth it.

Matrix 11: Dark Tunnels and Hidden Codes
Matrix 11 feels like a horror movie, and the passcodes here are often guarded by jumpscares.
The Landfill Control Room
You’ll find yourself in a subway tunnel with a train car barreling toward you. After dodging that mess, look for a body in a side room near the end of the path. That’s your Landfill code. Use it in the control room to open the shutter and grab a Fusion Cell.
The Underground Sewer
Adam will tell you that you need to power up an elevator. The code for the chest containing the Fusion Cell is on one of two bodies slumped together in the southeast corner of the room. It’s easy to miss if you’re rushing to get out of the sewers.
Rotten Labyrinth Hideout
Look for a little robot on a raised platform in the subway tunnel. You’ll need to swing across a pole to reach it. This code opens the golden chest in the survivor hideout later in the level.
The Great Desert: Puzzles and Lambdas
The Great Desert is where the devs decided to get clever. It’s not just about finding a body; sometimes you have to do a bit of math (or just read a guide).
The "Third Road" Statue Puzzle
In the Northeast sector, there’s a chest behind a statue. To get the code, find a data bank called "Third Road" on a shipping container. The document has a long string of 18 Greek letters. The trick is to take every third letter.
If you do the math, the code ends up being λλλλλλ (six Lambdas).
The Oasis Chest
Everyone loves the Oasis because of the fishing, but there’s a chest underwater. The code is hidden behind a shutter on the perimeter wall. You have to climb some handholds and jump across drones to reach the button that opens it.
Solar Tower
This one is high up. You have to fix the tower first via the "Reboot!" quest. Once the drones are active, you can use them as platforms to reach a walkway where the chest is sitting. The code itself is on a robot near the base of the tower, hidden behind some wooden crates.
Spire 4: The Home Stretch
By the time you reach Spire 4, you're near the end. The passcodes here are usually more about navigation than riddles.
- Maintenance Gate: You'll find the code on a memory stick belonging to Legionnaire 742. It’s right near the start of the Orca Space Complex.
- The Orca Engineer Suit: This is in a box near the third camp. Most of the codes in this area are held by robots or dead soldiers directly in your path, so just keep your scanner (L3) active constantly.
Why You Keep Missing Them
The biggest mistake people make is not using the Drone Scanner. If you haven't upgraded your scanner range yet, do it now. It highlights bodies and robots through walls.

Also, remember that some chests are "Mission Locked." If a chest has a red icon or says "Locked," and you've searched the whole area, it's probably tied to a bulletin board quest in Xion. You literally cannot open them until you accept the right job.
Expert Tips for Completionists
If you’re going for the Platinum trophy or just want all the Nano Suits, keep these things in mind:
- Point of No Return: Once you go to Spire 4, a lot of things in Xion and the previous areas become inaccessible. Make sure you’ve finished the "Recruit Passcode Specialist" quest before you take off in the Tetrapod for the final leg.
- Check the Data Bank: If you pick up a passcode and forget it, it’s stored in your menu under "Documents." You don't have to go back to the body to look at it again.
- The "Triangle" Shortcut: When you’re at a keypad, pressing Triangle will often auto-fill or display the code if you’ve already found the corresponding document. It saves a lot of back-and-forth.
To get the most out of your run, start by clearing the Xion bulletin board every time you return from a major region. This ensures that when you stumble upon a locked chest like Bar 99, you already have the quest active to find the solution. Focus on the Wasteland shrines early, as they take the longest to track down across multiple zones. Once you have the "Recruit Passcode Specialist" sequence, the rest of the game's locks feel like a breeze.
