Weird Tests was a psychological experiment created mainly by Dr. Rick Hayton. It worked like some kind of gameshow, where volunteers could participate and try to pass difficult challenges for high amounts of money. Their consciousness would be temporarily transferred to Joe's consciousness, which would be remotely controlled by Rick and other staff members. The place where everything happened wasn't physical in the classic way, but instead it was a mental location existing in the mental space. It had to be built and cleaned like a real set, but whatever idea Hayton had he could add. Before entering, volunteers had to create a fake name and avatar to protect their identity. The contestants, usually five per season, had to walk through ten rooms, chosen by the Doctor or his co-workers, each episode. In total, the rooms were one hundred. When they died, they didn't feel any pain, and just came back at the start of the room. They had five lives before they got eliminated. When room 100 was reached, Rick got the remaining contestants out of Joe's consciousness and gave them money. About the contestants that got eliminated, they got out of Joe's consciousness without getting paid.
The main people involved in Weird Tests were Dr. Rick Hayton, the founder and legal owner of the project, which had the whole idea, and his brother Joe Hayton. At the time of WT's creation, Joe was in a coma for more than twelve years. He couldn't even die, but he was alive. Even without any food, his heart would still keep beating. One day, the reason is something he'd like to keep private, Rick decided to take a look into Joe's mind, putting his own consciousness into Joe's mental space. It was an empty void, and he kept falling and falling, forever. His wife woke him up and there Hayton had the idea of creating Weird Tests. He noticed that, using various tools and injecting information into Joe's brain, he could manifest anything in the mental space. He quickly created simple building blocks and made the first room variations. He then worked on game mechanics and entities. He also noticed that, whenever he died, he came back and his corpse disappeared. Weird Tests was then created.
Since Hayton needed money to give out in the contest, he never revealed that he could just add whatever he wanted in there and totally control the place, so he hired janitors and created exits that automatically woke them up once their shift ended. The four janitors that never got fired and stayed all the way were Annie Belle, Mark Plunge, Karl Karly Karlson (which later legally changed his name to Karl Charlie Karlson for obvious reasons) and Matt Steep. Important project members other than Rick are unknown because they probably didn't want any backlash for working with him.
It was the tenth season of Weird Tests, everything was going well and this time the show had ten contestants to show that it was a big milestone. A man broke into the studio where everything happened and shot Dr. Rick Hayton, along with trying to shoot Mark Plunge, who just came back from his shift. Mark luckily managed to escape by putting himself in Joe Hayton's consciousness, making him invincible like Joe himself. While the contestants, the janitors and the other people involved were in this invincible state, he dismembered them and burnt Joe's body as no one else was there. This way, they couldn't wake up, as their own consciousness didn't exist anymore. This resulted in the players slowly going insane and being trapped forever in the Weird Tests world. The man somehow knew about the whole "injecting informations in Joe's brain" thing and removed the exit, making rooms generate infinitely, and players respawn infinitely, while still feeling pain. Right now, the ten contestants are still trapped in the Weird Tests world, while the four janitors escaped from there, came back to their bodies and inevitably died. A myth states that the contestants found a way to create new temporary contestants that can die by injecting themselves informations into Joe's mind. Who knows?
