The Backrooms Level 0: "The Lobby"

Level 0 is a vast non-Euclidean space resembling the utility rooms of a commercial building. All rooms in Level 0 share common exterior features such as worn plain yellow wallpaper, old damp carpet, scattered electrical outlets and improperly placed fluorescent lighting. Apart from these common features, no two rooms on the level have the same layout.

The fluorescent lighting at Level 0 buzzes at a constant frequency. This buzzing is noticeably louder and more intrusive than conventional fluorescent lamps, and checking the instruments to determine the source turned out to be fruitless. The most noticeable threat in the Level 0 game is the acute shortage of available resources; for example, the liquid impregnating the carpet has been deemed unsafe for human consumption, most of them are likely to die before they can find a way out due to prolonged dehydration, hunger and exhaustion. Entities Since the reports are contradictory and difficult to verify, it is unknown if entities exist inside Level 0. In addition, no interactions with other wanderers have ever been reported during research, as an individual wanderer is constantly isolated.

Inputs and outputs Entrances Level 0 and, accordingly, in the utility rooms, can be carried out randomly noclipping outside the boundaries in normal reality.. Also, many levels can lead to Level 0.

Outputs At the moment, there are five known ways to exit level 0.

Many factors will eventually lead to the corridors moving to Level 1. Overcoming the wall will lead to level -1. A break in the floor can lead to level 27. It can also lead out into the Void. In rare cases, wandering far enough in any direction can lead to the Manila Room. Sometimes you can find doorways made of glass. These doors lead to the 13th level.

The linear space in the game Level 0 has been radically changed; you can walk in a straight line, return to the starting point and find yourself in a completely different set of rooms than those that were passed earlier. Due to this phenomenon and the visual similarity between each room, sequential navigation of Level 0 proved to be very difficult. Devices such as GPS locators and compasses do not work within the level, and radio communication is severely distorted and often unreliable.

Above the ceiling tiles at Level 0 is a cramped, dark space about one meter high. The air in this room is musty and saturated with dust, which makes it difficult to breathe, and electric wires run along the ceiling in all directions. Attempts to use this space as a means of navigation are impractical, since ceiling tiles easily give way under pressure.
