When visiting Fristad Rock, go behind Franks facility and head down. You will walk into a bunker and a man greets you from behind a glass window.

He tells you he knows you, and then proceeds to let gas out from the floor. I have the iron lungs perk so I do not die from this

There is a hackable antenna which opens a box. There’s a note inside the box

Letter inside the box

Below the stairs to the left of the room there are levers which seem to have to be opened in some sort of order??

The room filling up with smoke

I can pull the levers, but after 3 have been pulled they reset. The levers are marked with the following numbers from left to right

132 122 123 142 222 023 323 027

Edit: there is a whiteboard behind the door with 2 numbers on it. Pull the corresponding levers and press the red button to stop the gas

I can see a trinket in the mans office so there must be a way in?

Edit: came back in the morning and there is a rocky entrance revealed. Inside it has a 4 digit code and tells Colt to ‘Shut it down’. Where can I find the code?
