HELP (Spoilers in Discussion)

[Purple Juice]

Okay, so I’m a bit down on my luck here so I’m turning to the Steam community to help me here. At this point I’ve made it to layer three. I’ve gotten past all of the gates and entered the sections with the monsters.
I was able to find a button that leads to the map on YouTube, but I can’t find anything else. I found a button, but I’m not sure what it did. There are also these Golden Monitors, and I know that they need the code 1997 inputed into it, but I can’t access the keypads.
Does anyone know where to go from here?

IMPORTANT EDIT: I have not found some of the videos needed for the codes but I’ve gotten two. One was for a room that is red, and another for the room that activates the golden monitors around the map. I can’t find the others. Can I get the codes? Or at least some help getting the other codes? I think one of the other locked rooms was called the Gallery.

IMPORTANT EDIT 2: I got every code but now I’m stuck trying to get all the golden monitors. Is there a tip or a guide I can use to make this easier? Like a map of where each monitor is?

Have you gotten the "crystals" video? It should help you out

I'm sorry that I don't know the answer to your question, but may I ask what the 3 gate control keypad codes are? I'm watching my BF play and neither of us have a clue atm (he's on 2/3 so far).

I’m unsure myself. I got past the section but it may have been due to a bug? There should be three different rooms with different buttons. Each one has their own puzzles to solve with different codes. I know that one of the rooms (the sewer looking one) needs you to have a specific achievement with a weird name. That achievement has the code. I don’t remember the other 2 rooms exactly, but they shouldn’t be too hard to figure out. Then you’ll get to the part I’m talking about in my first post. Hope this is helpful!

No, I didn’t know there was a crystals video. Where did you find it?

Inside the big building with the 2 Silvertech computers and the hallway that leads to the blue room. There's a red button in the big building that will open the video for you. That's what you need, or at least one of the things you need.

I finally figured it out. You listen to a snippet of Ode to Joy and have to figure out how many times EF and G are in there, followed by a 9. E is 9 times, F is 4 times, G is 4 times, and the last number is 9. So the code is 9449.
