The "0451" code in Gone home, Bioshock and Bioshock Infinite

[Ball_Joint_Doll]

all three games have a 4 digit eneterable code that is "0451"
In Gone home, it's the file cabinet in Terry's office.
In Bioshock it's the first safe in the medical pavilillion.
In Bioschok Infinite it's the password to the elevator with the passcode written on the note pad.

Soooo, Is this code seen in Bioshock 2 ?

I'm a lazy bum, so look at this:
Bioshock Wiki[bioshock.wikia.com]

Also the first safe in Dishonored needs this number too, I believe.

It is also the first code in both 'deus ex' games.

How did you find the 0451 code though? Where was the ingame clue?

Nevermind, I got it. It's in the library, written on the folder that contains a letter of dismissal from his editor.

Actually, I always try that code in all games... Except it didn't work in Stanley parable.
