 In this video I'm going to be talking all about Backrooms Level 21 aka The Number Doors. This one is just straight up dangerous and is pretty unique as well, so just sit back and relax. Let's hop right into it, shall we? Also you should hop right down to the sub button and press it if you want to see me get the Backrooms Pass. Alright, now let's get to the video. Backrooms Level 21 is classified as a Class 4 difficulty, which is crazy because it's the first really difficult one in a long time, and it's unsafe, unsecure, and has a medium entity count. The level is made up of 4 specific really long hallways with random places and random doors in them. Each of those long hallways is specifically around 26 miles long and they all meet together in the middle of the level, so they're kind of shaped like an X all going towards the same point. Now I'll get into what the halls look like in just a second. First I want to talk about that middle area where they all meet. So the middle area is this smallish open room with chairs and desks, kind of like an empty classroom which is creepy as it is, but I guess a good thing is that there's no entities that spawn in this area, so it's pretty safe. The hallways themselves are constantly changing. They can shape shift into something completely different at any given time, so their shape can change, their layout can change, and they can become impossible to go through in some rare occasions, but the one thing that always stays the same is that the doors on either side of the hallway stay in the same spots. No matter how much the halls actually change themselves, the doors will still be in the same side and in the same or similar spots. These doors can lead to random places in the back rooms, even negative levels or sub-levels, which is pretty rare for normal back rooms levels, but you know, it's also really dangerous because you never know where it's going to send you. Most of the time the doors just take you someplace else in the level though, so that's cool. But it's also not recommended to just open random doors, like don't just rip open the first door you see because you might get sent to a really dangerous place. There actually are some doors that are known and cataloged to lead certain places, but there aren't that many, so I'm going to go ahead and read them. Doors labeled 105, lead to level 0, and doors labeled 356, lead to level 356, it's a shocker. Doors made out of sandstone can lead directly to level 46, doors labeled 34, lead to level negative 6, and of course, they had to put it in here, but doors labeled with a smiley face lead to the level fun, yeah. And doors labeled 8 through 20 all lead to their respective levels, so if you go through a door labeled level 8, you'll end up in level 8, and the doors don't have any labels sometimes can lead to level 1.5, but yeah, those are the ones that are set in stone. But like I said, the other doors can just lead to completely random spots, so just don't risk it. Some of those hallway sections can also be filled completely with creatures and entities, but which specific hallways are filled and where they're at also changes, just like the hallways do. So it's impossible to tell you which specific places are entity infested. So the most common entity here is actually clickers, which are relatively harmless, so that's nice. But there also have been completely unknown and undocumented entities seen here as well, so make sure when you round a corner, you watch out. This level is also home to random items on the walls, like almond water or level keys, or in some rare cases, fire salt, which is pretty rare and useful, although you're supposed to avoid all level keys here because they're untrustworthy. So there's that. There's also one specific door in this level called the exit door that if you open it, it leads to three pitch black hallways, and they're really long and they're much longer than the ones in the main part of the level, but these hallways past the exit door are infested with all types of creatures, but they do have some really nice materials and objects in them, like loads of almond water and fire salt and stuff, but you'll have to fight off a bunch of creepy monsters, so I'm not sure if it's really worth it to do that, but to each their own I guess. There aren't any bases here since the layout changes all the time and you really couldn't sell one up if you wanted to. And to enter, you can go through a random break in the wall from level 13, which typically has a high pitched ringing coming from it, so that's how you know where you're at. And to exit, just go through one of those doors that I talked about earlier that are already mapped out and their exits are confirmed, and you should be fine. Alrighty, that was my explanation of Backroom's level 21. I hope you enjoyed it. I really like this level, you know, it's nice to finally have an extremely dangerous level that's constantly changing and it's kind of a toss up if you want to go, you know, it's pretty cool.
