Level 170 is the 171st level of the Backrooms. It was discovered by an anonymous wanderer on 19/03/2014.


Level 170 is a dry field with concrete boxes laying on the ground. The level is finite, being about 7 kilometers long and 400 meters wide in a rectangular shape, making it one of the smallest levels, with a surface area of 2.8 km². It is surrounded by a sparse forest on all sides.

The surface of the level is covered in dry grass, wooden branch debris, and, rarely, dry bushes. The level is relatively warm, with temperatures varying between 25°C and 35°C. Level 170 has a rather confusing time cycle — when the sun sets, it instantly rises on the other side of the level, skipping the nocturnal period. An average sunrise-sunset day on Level 170 lasts approximately 6 hours. Weather in Level 170 is unaffected by the odd time cycle. The sky has been observed to change, sometimes lacking clouds entirely and other times being fully encompassed by them, and in other cases, even rain was reported.

The Concrete

"The Concrete" is a name given to a group of structures made out of concrete that can be found laying on the ground of Level 170. The individual units that comprise each structure have the same measurements of 2.5 x 2.5 x 5 meters, and are made from hollow concrete slabs that are each 25 centimeters thick. They appear to be placed in random locations, yet all the slabs in Level 170 face in the same direction, and are aligned in a grid-like fashion. It is estimated that there are about 1000 such structures on Level 170.

There are three different types of these structures, each type has different characteristics.

Type 1

There are approximately nine hundred of these blocks located on this level. This type of block does not have any special properties at all, and can be found laying on the ground. They are often inhabited by colonies of Deathmoths.

Type 2

About one hundred concrete boxes belong to the Type 2. They possess a property which makes them act as a cluster of interconnected portals, allowing wanderers to freely walk through them and appear on the other side of the level, which makes this level quite easy to explore. Not much is known about the reason of portal-like nature of this type of The Concrete. Type 2 blocks are currently under the M.E.G. analysis.

Type 3

There are three boxes located near the edge of the level that are placed in a nearly perfectly aligned shape. It has been confirmed that Type 3 blocks are beneficial to human minds. Wanderers that have stood near these blocks have stated that they felt their mind to be much "clearer", and that it was much easier to recall distant memories when standing between these concrete structures. All wanderers proclaim that they felt very safe when in this area. Many have grown addicted to these structures' effects. Some can sit in this area for hours, as it is easy to lose the track of time there. M.E.G. operatives discourage staying there for too long, because there isn't enough information about this type, and it is speculated these blocks may be alive.

The Forest

The forest of Level 170 is an area that acts as a border of the solid part of this level. Average distance from edge to edge of this section is about 15 kilometers. The more you explore this zone, the sparser the trees get. The emptier parts of the forest are infested with Reviooks, making it quite hard to explore this part of the level. Travellers delving into this part of the level are advised to stay alert because of the aforementioned Reviook infestation.


  • Deathmoths are commonly found inside some of the boxes of Level 170, they make nests on the walls of these structures. Deathmoths of Level 170 are generally hostile, and they give off a characteristic smell. It is highly recommended to always check if the concrete box has been infested, as they spit acid on the wanderers who disturb them.
  • Reviooks populate the borders of The Forest of Level 170, waiting for the wanderer to stand still on the ground, so they can grab them by their feet. The only way to get around them is to run forward nonstop, or quickly return to the start of the forest.

Bases, Outposts and Communities:

There are no known bases, outposts, or communities on this level. The presence of aggressive entities and lack of any food make this level hard to sustain any human form of life. The level is considered to be relatively safe if you stay in the right areas of it and have the right equipment.

Entrances And Exits:


There are currently only six known ways to enter this level.

  • No-clipping into the trees of Level 39 occasionally takes you to the forest of Level 170.
  • Some of the concrete office rooms of Level 81 lead to the Type 2 concrete boxes of Level 170.
  • No-clipping through the concrete wall of Level 162 leads to a Type 2 concrete block in Level 170.
  • Getting lost in the hallways of Level 108 results in the lost traveller entering Level 170 through one of the Type 2 concrete boxes.
  • Backing out of the forest of Level 192 leads to Level 170.
  • Entering a certain hole in the walls of Level 797 leads to Level 170.


There are currently only four known ways to exit this level.

  • It is possible to enter Level 10 by running deep into the forest of Level 170, as it gradually progresses into Level 10. However, after entering it, you wouldn't be able to return to Level 170, as it would simply disappear from the sight of the wanderer for an unknown reason. This way is considered the most reliable, yet likely the most dangerous.
  • Some of the Type 2 concrete boxes in Level 170 lead to Level 162.
  • Entering through a green door found within a specific Type 1 concrete box within Level 170 will cause you to enter into a B class tunnel in Level 181.
  • Occasionally, isolated xates trees can appear in the forest of Level 170. Climbing up said trees will sometimes transport you to the top of an identical tree in Level 204. It is to be noted that the mentioned trees are extremely rare.
