They all woke up in a strange room. It was all white, from up to down, it just had a door and near it a table written on it: "Enter the door, please".

They stood up from the chairs and entered without saying anything... they just looked at each other like they weren't familiar.

After they all entered the door, they saw a blue field with a big monitor on the white wall and many other people looking at them, just like they were the last ones to wait...

Right after they closed the door, the big monitor turned on and there was a guy on the screen that started talking about a game that they will play soon, right after 5 minutes of the game introduction.

He said:

The name of the game is "Survive until the end, if there is an end". The game rules are that all the players will be separated into 1v1 with knives until the last one to survive, until the end, that will be the winner. But the game will not be so easy and fast... (To be honest, it will be a very, very long, tragic and painful game, especially bloody...)

Then he just said: "Happy game!"
