Level 0.3

Description
Level 0.3 is a sequence of circular hallways which are connected by square rooms with doors on one side or both. These doors are either dark blue or light gray, meaning that any other colored doors are either entrances to other levels or fake (meaning that they don't open or have walls on the other side). The main doors are always metal, doors with other materials lead to other levels or to nothing at all. The hallways vary in sizes and sometimes have a room in the middle of them. These rooms can include stadiums, apartment complexes, and theaters. There will be pipes on the roofs of the hallways, and a lot of the time they will be leaking either an extremely hot or extremely cold dark liquid. It is not recommended to interact with this liquid under any circumstance.

On the outer walls of these hallways, there are windows that show a fake reality. These windows are nearly indestructible. There is a chance that there will be stairs in the hallways. Going down always leads to glass doors, outside the doors is the same fake reality as seen on the windows. After walking for 200 meters in any direction, there will be a big concrete barrier that extends upwards forever. Going up the stairs will lead you to another spot in the level, usually 10 to 50 meters away.

About 110 km2 of land has been discovered.

Entities
There is a little amount of entities here. You can very rarely find Facelings and Skin-Stealers in the rooms between the circular hallways. It is rumored likely that there are window entities in this level, but none have been seen.

Objects
In the corners of some rooms, there will be Almond Water and Liquid Pain. They are both contained in opaque black bottles. Try not to confuse them, it could end up badly. You can find outlets in most places, they are usually 15-25 meters apart. The Wi-Fi here is decent, being exactly 17 Mbps in every area of the level. The Wi-Fi's name is "circ2010000203", and the password is "yourenotsupposedtobehere". However, connecting to the Wi-Fi will make it easier for entities to find you.

M.E.G. Vesca Base
M.E.G. Vesca Bases are located in the levels that are generally harder to explore/document. Most of the people in Vesca Bases are people who have been trapped in the backrooms for a while now. The Vesca Bases are usually in the middle of the levels. Most of the time members of these bases are willing to give you some almond water and offer you some time to rest, although this is risky because this level is not thoroughly explored.

Outpost Meltan
The Backroom Colonists are in a relatively hard to explore area, meaning it is decently secure. They are also stocked with supplies and are pretty fortified, with a population of 36, so a solo raider can't really take the outpost on. They're willing to trade whatever resources they have on themselves at the time, mostly including equipment and almond water variants.

Entrances
One can enter this level by noclipping through the inside of the elevator that leads from Level 2 to Level 4, or by entering a blue fire exit door in Level 0 or any of its sub-levels.

Exits
By noclipping through a strangely-colored wall, one may be sent to Level 12. You can find light blue doors with some small rust to go back to Level 0. Going through any glass doors will send you to a Fake Reality.

Walking through yellow doors with a smiling face will bring one to a party! =)
