You will run into plenty of locked doors, security panels, and computer terminals in RetroSpace that demand specific codes to open. Finding the solution usually involves hunting down clues scattered nearby, which are helpfully labeled to keep things in order.
It is surprisingly easy to miss a small note tucked away in a corner, so don’t get frustrated if you spend more time searching rooms than actually progressing. Having the numbers on hand is a massive time-saver when you just want to keep the momentum going through the ship.
Before you start typing, make sure your inventory is clear and you have scanned the immediate area for any lingering audio logs or documents. These files often provide the context for why a specific code exists in the first place.
If those logic puzzles are slowing you down or you simply prefer to skip to the terminal access, I have compiled every known sequence for you here. This list covers the Stasis Chambers, Nexus areas, Medical Section, Security Section, Engineering, Borealis Garden, Great Dome, and Grand Station.
RetroSpace: All Codes & Passwords
Stasis Chambers Codes
| Location | Code |
|---|---|
| Janitor’s Room | 0937 |
| Security Override | 1477 |
Nexus Plaza
Security Override
Input the Code: 4712 to unlock the terminal here.
Nexus Gardens
Security Override
The security override requires you to enter Code: 5315.
The underlying math for this one uses the following number pairs:
9 – 4, 6 – 3, 3 – 2, 6 – 1
Storage Room
Use Code: 1212 for the storage room access.
Medical Section Codes
| Location | Code |
|---|---|
| Security Override | 2177 |
| ICU | — …- ….. .— (Morse Code) |
| Quarantine Lockdown | 1234 |
| Morgue | 2236 |
Security Section
| Location | Code |
|---|---|
| Cell Room | 3333 |
| Security Override | 5973 |
Engineering
For the engineering security override, enter Code: 0715.
Security Section 2F Codes
Security Override
Use Code: 3757 to clear the override.
The clue is presented as 3, 3+4, 1+4, 1+2+2+2.
Adding these up confirms the sequence is 3, 7, 5, 7.
Door to Dahlia
Input Code: 7375 at the door.
This is derived from the clue 3+4, 2+1, 3+4, 1+4.
This math sequence correctly resolves to 7, 3, 7, 5.
You will find these clues split across two distinct locations. Head to the bathroom for the first half, where the following values are defined:
- | = 1
- – = 2
The rest of the cipher is tucked away in a hidden room in the recreation area, specifically past the steam pipe. That location defines these additional values:
- | = 1
- – = 2
- ( = 3
- ) = 4
Combine your symbols to solve the final numbers. For instance, finding O and S symbols means using ( + ), which results in 3 + 4 = 7.
If you enjoy finding these extra bits of world-building, make sure to track down the audio logs as well. They really add depth to the setting.
Borealis Garden
Security Override
Use Code: 2468 to override security here.
The logic here is based on two variables:
- A = 2
- B = 4
- A + B = 6
- A × B = 8
Putting those results in order gives you 2468.
Great Dome
Moebio
Enter Code: 3123 for the terminal.
The colors you see correspond to numbers in this specific sequence:
Red = 1, White = 2, Green = 3, Red = 4
Grand Station
Luxury — Outside Security Override
The entry code is 1999.
Luxury Security Override
Depending on which version of the game you are running, the required code will change:
- Before patch: 9119
- After patch: 1919
The hint provided for this one is cryptic:
1i, 9x, 1e, 9t
Stick with 1919 if you have updated to the latest patched version.
Police Station Security Override
Use Code: 9947 to bypass the station security.
Police Station Monitoring Room
The monitoring room responds to Code: 0001.
Control Zone Security Override
Enter Code: 2237 to gain access.
Control Zone Captain’s Office
The captain’s office terminal requires Code: 7649.
