Infinite Buildings

Infinite buildings are very dangerous anomalies that lure reckless travelers inside. As soon as you go there, you immediately notice that inside the plan of the building does not match its appearance from the outside. Many careless people go inside as if they were going into an ordinary building. As soon as they turn back, they discover that the exit has disappeared. This is where the adventure begins.

Navigation
Each room inside the building has at least 2 entrances. Maybe more. These rooms are completely random, look like ordinary rooms from different buildings, such as an office, bedroom, or basement. But such rooms never existed in reality, and they exist only inside infinite buildings. There is only one rule in this world: you will never return back.

Threats
For the rest of your life you will have to be located and move in an endless building. During all this time you can meet threats to your life. This can be a collapse of the ceilings, bare wires or damaged pipes with hot water. But you are lucky if you have not met the real threat of endless buildings - terrible creatures that can meet you completely by accident. No weapon will help you in the fight against them. The only way to survive is to run.

Introvert Strategy
You try to collect as many useful things as possible and then barricade yourself in one of the large rooms, where all the entrances have a door. If you close the door and wait a few hours, the room outside the door will change. This way you will check the room behind the door several times a day in the hope of finding food. Just do not go too far from your "base", it may disappear. There is a saying: if you came across a locked door, then a dead introvert is behind it.

Raider Strategy
You do not stay in any room for too long, you keep going all the time, taking with you only everything you need. The most important thing about any raider is a backpack.

Other Info

 * If you are lucky enough you may encounter another human. Not everyone is friendly, some of them closed their mind. But that fact proves that every infinite building is somehow connected to another.
 * The only way for us to know what is happening inside infinite buildings is "streamers": it is people who had laptops or phones with then when they got trapped. In some rooms for some reason, there is a wi-fi, so people can connect to the internet. None of them had streamed for too long, as the power just goes off. Some individuals break the ceiling lamps to access electricity cables, so they are getting renewable sources of energy.
 * Some of those streamers are doing various experiments with the dimension they are trapped in. Here are some of them:
 * Breaking walls with a sledgehammer: there is just a thick (maybe endless) layer of concrete. Same for the ceiling and floor
 * Using GPS: it always shows the coordinates of the infinite building you went to.
 * Fighting with horror creatures: no one of the experimenters survived. Video material proves that they are immune to physical wounds.
 * Observing the pocket watch: time is always synced with the time from the outer world.
 * Placing any object on the seam between two rooms and wait until room will change: the object got sliced in half. (Maybe it is a way of killing those creatures?)

Video and Picture Documentation
There are a lot of photos and videos taken from infinite buildings. Some people say that the backrooms are a part of infinite buildings too, but that isn't true. Even just a picture gives chills, imagine being here by yourself.
