Backrooms 001 - Entitled "ZERO"

This video was sent to us by anonymous. We are still processing the several hours of very damaged VHS that reveals the unfortunate no-clip experience of what appears to be a facility janitor. No additional information on the subject at this time, but he may yet be stranded in the liminal nexus known to the internet as the notorious "Backrooms". The area or level where this footage was taken is somewhat unfamiliar to us. Our best guess is that it is a sub-level of Level 0 which is densely populated by office objects. If anyone has any other information regarding this video, or more about the black-mold entity near the end, please leave a comment. Thank-you.
