Behind the scenes is where one of the urban myths later shown to be genuine took place. The buzzing of the lights and the peeling edges of the wallpaper were known to lure infatuated couples into a tragic embrace in the corridors, where they would afterwards be murdered. There, they would face the most catastrophic of all potential outcomes. Beyond the confines of our world, something horrific skulks in the darkness of the theatre's backstage tunnels. There is a story going around that the city home to the famous offices also houses a beast ravenous for human blood. She searches the dimly lit streets for the person who piqued her interest enough to bring her there in the first place.

What is Backrooms 3: Boss Fight?

There is no other way. While you are there, you are required to flip five switches, so you should get started looking for them right away; the sooner you discover them, the better. However, as you make your way through the streets, which appear to be vacant, you notice a significant shadowy figure roaming about.
