The final code?

[Daniel Sabino]

Hello everyone, I've been reflecting on some issues related to the alternative ending of the game. And, I've been wondering about the "code" needed to open the door.

I've seen various tutorials explaining how to achieve the alternative ending, but none have explained "how" they arrived at this code.

Is there a way to discover it within the game? Or is it just a matter of "trial and error"?

P.S.: My question ignores factors such as analyzing the game's scripts, etc. I would like to know if, as a player, we are shown this code or something similar at any point?

Here is a video explaining the origin of the code:

IIRC you need to reproduce the sound near those spheres.
