The Secret code

We reveal a unique Easter egg that spans an entire genre

If you were to play through the first section of every immersive sim in succession, you might notice a pattern. In System Shock, the code for the first door is 451. In System Shock 2, it’s 451000. In Deus Ex, you can open the van at UNATCO headquarters with the code 0451.

The code for the first safe in Dishonored is 451, it is 0451 for the first locked door in Bioshock, and the drawer of a filing cabinet in Gone Home. As you might have guessed, this isn’t a coincidence. System Shock first used the code as a reference to Ray Bradbury’s novel, Fahrenheit 451, and the many immersive sim games that followed have continued the tradition.
