The Steelrooms

If you break a distinct looking panel in a metal shaft, you'll end up in The Steelrooms.

The Steelrooms is a secret level, and from what little amount is known, a potential refuge from the insanity of the other rooms as long as you stick by the advice of the posters.

Description
Little is known about The Steelrooms, with only one report. This report read:

It's Saber here, writing a report on an experiment i'm conducting; breaking a panel in a shaft.

I picked up a crowbar from Level 1, and after walking for a few hours, I managed to find a shaft.

''The panel was quite strong and had the appearance of brushed metal. After about 30 minutes of trying to pry it off, it finally came out, and there was another series of corridors inside it, all metal.''

As I walked in, the sound of air gushing through what appeared to be standard vents will engulfed my ears.

This place consist of widish clean steel halls dotted with vents along the top of the walls.

It's quite lonely in here, I wouldn't say any entities inhabit this place as a tool & quite some effort is needed to break one of these panels in a shaft in order to enter.

I'll keep exploring and update you later.

''

I'm back... I found some old posters on vent maintenance, something about not opening them, I also found a screwdriver which fits the vent screws. I may as well try this...''

''

Okay, nothing happened yet. I'm currently crawling through a vent. For some reason the further I go the quieter the gushing air gets.''

''

The vent came to a close, and I exited it.''

''

Now i'm in an unknown place... there are rotting wooden floorboards, dim lights here and there, and it all gives off an attic feel.''

''

What's that sou-''

End of report

From what is written, the steelrooms themselves are fairly safe because of their challenge to get into, however while wandering through The Steelrooms, you may come across posters on vent maintenance. Occasionally you may also find screwdrivers which can be used to unscrew the vents. The level which was described in Saber's account is Level 19.
