Level -4 appears as an infinite tunnel made out of materials constructed with carbon. A majority of carbon dioxide gets released into the atmosphere. Unlike the real-world variant, the levels version is safe for breathing in. The interior of Level -4 is cracked and highly unstable, making it a must for you to make it out as fast as you can. The levels lighting is faulty. Even light sources like flashlights will flicker with no apparent means of why it happens. Some people say that the Smilers found in this level have gained the ability to do so, while others say it was because of the carbon like atmosphere. This level is split up into 4 sectors.

Sector 1

Sector 1 is the most stable part of the level. Carbon dioxide levels are really high and emit a sweet smell. Entities are not so prevalent within this sector other then and the levels own entity, . This sector is where you start at and is the main area of the level. Around every 5 kilometers, an intersection will appear. You can either decide to go forward, back the way you came, left or right. No air is provided in these intersections so make a decision before you run out of oxygen to breathe. The levels walls are made of Cast Iron, and lighting is at its finest.

It houses items similar to that of space for unknown reasons. These space-like objects are safe to handle, with the threat level of these objects being low at best. Should one drop it, the object will create a mini black hole, sucking the wanderer before disappearing from the face of The Backrooms. Other weird occurrences within this sector are the starry ceiling. Nobody knows why the ceiling acts this way, but most presume its due to the carbon dioxide levels causing hallucinations. When travelling far enough in this sector, a door will appear. Entering this door will take you to Sector 2. You can also find light at the end of the tunnel to get to .

Sector 2

Sector 2 has low carbon dioxide levels, and the walls are made out of rubber. Entities here spawn frequently, with the most common in this part being . The effects of sanity are deeply impacted by the low carbon dioxide levels, and, for no real explanation, drains faster than normal. The sector is very damp, and at times can increase the carbon dioxide level to medium or high. You will be presented with pipes that spew water particles into the air, which explains the damp like environment. Food can be found in vending machines and are deemed safe to eat. The vending machines which, fortunately enough, have hallways behind them that contain . These areas are hard to access however as you need to push the machines out of the way. The vending machines are typically heavy, so topple them over if pushing isn't enough.

Strangely enough, doors can't operate properly. No matter how much you push or pull, they don't open. This can be explained in one of two ways. Either objects are behind the door, holding it shut, or it has a lock that can only be accessed from the other side of the door. The lighting in this sector is not great, as the lights go on and off at random intervals. Due to the low amounts of carbon dioxide, the lights are not able to function as intended. Intersections are non-existent in this part of the level, meaning this sector goes onto a straight path. Finding a crawlspace will lead to Sector 3, and sometimes Sector 4, but isn't recommended. A ventilation shaft can appear every so often, and entering it has a high chance to take you to Sub-Sector 2.1.

Sub-Sector 2.1

Sub-Sector 2.1 is what is presumably an infinite ventilation system. Not much is known about this sector and its carbon dioxide levels. There is a constant blue hue that shines throughout this sector and has been deemed "calming" upon wanderers. This "calming" sensation has made wanderers aggressive towards each other, and any encounters with these crazed wanderers is considered a death sentence. The wanderers are seen with knifes in their hands. As to how they got these weapons is still a mystery. The only exit out of this sector is via breaking any vent grate which will lead to Sector 3.
