Level 3 is the 4th level in the Backrooms.

Description
In Level 3, the rooms are smaller and hallways are more claustrophobic than in lower levels. In this level it is easy to find random objects, some of which can be very valuable, such as lighters and weapons. Level 3 is also the level where the WiFi is the strongest.
It's ominous, but for good reason; Level 3 is home to by far the most entities. Pipes line the walls and ceilings of this level, which makes it easy to distinguish from the previous levels.
Due to the sheer number of entities inhabiting this level, it is recommended to head to the next level quickly. However, there are lots of useful objects lying around on Level 3, so it can be beneficial to stay and collect items if you're confident. This is also the only confirmed Level with Smiler Exterminator
Colonies and Outposts
Due to the nature of this level, no known confirmed colonies or outposts have formed. However, there have been rumors of a group consisting of rabid people turned insane by the Backrooms.
Of course, these are just rumors and should be taken with a grain of salt, as no known evidence of this has surfaced.
Leaving Level 3
The only way to leave Level 3 is through elevators which often lead to Level 5 and rarely Level 4. You can also go back to Level 2. You can also get here from the Debug Room.
