The Deep Down is one of the largest Backrooms levels, covering the bottom of any level that can generate holes, slides, and chasms.
A recreation of what the level looks like.
Class 3: Unsafe, Unsecure, Minimal Entity Count
Entering
The Deep Down is always located far under any level with a way to go downward, the easiest way to go down is through slides which are slanted holes that are confirmed found in Levels 1-3 and Underooms Level 0. You will slide down at a fast pace for roughly 10 minutes before you can hit the Deep Down. Holes can just appear anywhere in most levels. Chasms are found between two levels that can generate chasms, and they usually stretch all the way down.
Deep Down
The Deep Down is a dim-lit pathway of tunnels with a few sub-rooms. The walls have hints that they were light, but the paint is mostly worn down to reveal dark concrete-textured stone, the floor is often dirt-ridden, sometimes bits of it are broken off, and the whole level stinks of foul odor produced by rotting bodies of past explorers. The tunnels have tiny changes of elevation, like 25 degree slopes, but they always eventually go back down. Pipes rig the ceiling, some of them leaking unknown fluids. Sometimes the floor will change to look like a catwalk, and in the gaps you can see deep down a flood of many fluids mixed together. It is presumed this multi-liquid is lethal. Entities are stronger than normal in this level and it is unknown why.
Sub-rooms
The Sub-rooms are spaces unlike the usual claustrophobic tunnels that cover the majority of the Deep Down. There are a few sub-rooms that have been confirmed. These include:
- A room around 20m tall. Big pipes go through the room and the floor is flooded with the aforementioned lethal fluid.
- A room with a few chairs, tables, and one smartboard. The smartboard usually has text on it with survival tips. These are the known phrases. "If you hear screaming, do not follow it." "Do not drink habanstis." "Stay away from any danger, they are more powerful here." Habanstis is the presumed name of the mysterious liquid.
- A room with multiple streams of the strange liquid intersecting. There are four corners in the room connected by shielded catwalk. Each corner has a ladder downward leading to the tunnels and a few levers which control the flow of one of the streams. Where the streams intersect, there is a grate where they flow downward to an unknown location.
- A morgue-esc room with the bodies of entities killed. It is assumed the entities make these morgues for their fallen.
History
The Deep Down has been known to exist ever since the first few explorers went down the slides in Level 0, making it one of the earliest-known levels. Early pictures of the Deep Down depict a level not too far from the one today. One group of around 150 heavily-armed navy seals went down to secure the level, their dead bodies are now used as markers by explorers to tell where they are. A few major groups said it was top-priority to secure the area for research on the backrooms, but despite their best efforts, no colony has lasted longer than a year. One researcher ingested the "habanstis" and mutated into a Skinstealer, an unheard of outcome for the time. The Deep Down became the Mount Everest of the Backrooms, a challenge only the strong-willed or crazy would attempt, one that had a miniscule success rate, and one that had very few ways out. However, over time it was forgotten about, outclassed by newer discoveries, and it was mostly forgotten about.
Entities
Entities are rarer than normal here but also stronger than normal. The current estimate is 3 entities per sq. mile, an astonishingly low number. Insanities are the most common entities for this level, as the poor conditions get to people. However there have also been sightings of hounds, skinstealers, and facelings. Partygoers used to be in the level, evidenced by early photographs. However, the partygoers were unable to reproduce in this level, and they were eventually wiped clean from the level during the time it was popular. Finally, there are remains of what is suspected to be a Neanderthal caveman, which is rather unordinary, as it is believed the backrooms weren't discovered or didn't exist then.
Colonies/Outposts
There are no known colonies or outposts, but there are ruins of what were at one point colonies or outposts.
Exits
The Deep Down has four exits, exactly four. There are four fire escape doors on the four sides of the level. Reportedly, one brave explorer found the left-most door, and when he opened it, he wound up back on Earth. He is the only known person to escape back to earth from the Deep Down.
