A dark earthen room. Cold air. A tunnel leading out into more, deeper darkness. Two people awaken. In the room, there is a single tape recorder. One of them presses the play button. A cheerful female voice begins to talk. Her clear voice is a bit startling in the crisp air. "Hello. Good morning, afternoon, or evening. Though I guess where you are right now, you can't tell." The woman chuckles a bit. She sounds eerie to you for some reason, the way her happy tone seems to pierce the gloomy veil of your surroundings. "I know you're very confused and can't remember anything. Don't fret, for it's all in the procedure. I know you have many questions. However, I'm afraid my time is a bit limited. So I will try to answer all of your doubts as best as I can. Let me introduce you to your predicament." "You are currently in the…oh, what shall I call it? Let's call it the Tunnels. The Tunnels are a series of catacombs buried deep in the ground. It is like a maze passageways and rooms. The rooms vary in many ways. Also, you are armed with a gun. Right now, it only has one bullet in it. You might find a room with a few supplies here and there...though they'll be rare. Use your supplies wisely!" "Beware, for other things lie in the Tunnels. Things that will make your very blood freeze in your veins. You must find a way to overcome them. You must survive in the Tunnels. That is your purpose. Do whatever you can to survive. Whatever it takes. There is an exit to this place. If you survive, you can find it. You'll find salvation greater than anything you can imagine." "I am not here. This is simply a voice. And the only one you will ever hear for some time now. I will not tell you who I am. Until you survive, that is." The recording ended on a simple, chilling note. "Survive. For it is essential for all of us."
