Backrooms is one of the scariest locations in the Garry’s Mod sandbox. This is a parallel universe, where instead of the sun you will find only the hum of fluorescent lamps and endless yellow labyrinths. But don’t let the tense silence of this place fool you. The backstage corridors are not empty. Bloodthirsty monsters live in them. And they don’t like strangers. As soon as you were in this place, the monsters found out about you and went hunting. Run, hide and look for weapons. It will be very difficult to survive.
