You Mean I'm a Player in the Backrooms?

The mysterious game Backrooms Disaster suddenly appeared around the globe, and a million players plunged into a world of moldy yellow walls and buzzing lights. They can come back to life, but feel every pain for real. They trade death for information, using almond water, fire salt, light, and safehouses to pry open a way through despair. The Backrooms were supposed to devour people. Now the Fourth Calamity is turning the tables and blazing a trail through them.
