Fallout 76 Out of the Blue Code to gain entry to the lab area is:
- 12 11 22 13 – Open
- 8 22 8 26 14 22 – Sesame
- 8 22 22 23 – Seed
The first hint is to collect the paper with the code “Open Sesame Seed” note from the table. Then use the number conversation chart on the wall with parallel number codes to each letter. With this, you easily get the secret code and enter it in the keypad.
This is 12 11 22 13 – 8 22 8 26 14 22 – 8 22 22 23. Select the code options as the first, second, and third phrase of the password respectively, to open the door to the lab. Then you’ll progress through the underground tunnels, clearing the fake gas leak that has sealed the tunnels’ entrance door.
Make sure to have the best weapons and armor. As you will have to clear the area of Strangler Feral Ghoul, & even a Sheepsquatch Imposterling. This might prove tough depending on your level. Finally, investigate the caravan site to complete the Out Of The Blue main quest in Fallout 76 Steel Reign update.
