Sadly, this area is kinda randomly generated. It works in a similar way to the Dark Warehouse. To investigate the area, you need to listen to the music, if it gets quieter, you are getting closer to the connection with Static Noise Hell. A recommendation is to enter two blocks into any of the passages you find, then listen to the music, if it doesn't get quieter, go back and select another passage. Sometimes there won't be a passage that makes the music quieter, in this case, just select the one that doesn't change the volume of the music.
Other important elements that you can find in the area appear at random.
