Welcome to the Machine.
I don't know what you did, but it must have been horrible, to be sent here. The Machine is a very, very special prison. Only the worst criminals are sent there. It has an entrance, but... it doesn't have an exit. And nobody but the prisoners enter. There are no guards, no doctors, no nothing, but the prisoners themselves.
Or is there? Well, lets all just agree that they are the only HUMAN thing inside it.
For it won't be long till the prisoners start noticing other things inside The Machine, things that are not human... nor from nature. But that isn't the worst thing. The worst thing is the prison itself... It hears you, it sees you, and it can even talk to you... The Machine IS alive, and she likes to play with her prisoners.
This is your punishment, survive from, not only The Machine and the things that it holds, but also from the other prisoners. Rapists, murderers, thieves. Without guards or anything, you have to try to work together, but... how long will that last?
Well, we will see. We all the time in your world, because you'll be here forever.
The Machine is inspired my movies like Alien and Donnie Dark, songs like A New Machine Part 1 & 2 from Pink Floyd and SPECIALLY by the Silent Hill games.
The Machine is a horror semi-open world canon, in which a group of prisoners explore the place, and hopefully find the secret of The Machine and a way out. This RP has an proper beginning and ending, it's not a never ending story, and I expect it can last for, at least, a couple months.
