The Stranger in the Bunker.

You opened your eyes. Your head was aching terribly. And your whole body, for that matter, was too. Everything in your mind was as if in a fog. (you have amnesia)

Looking around, you didn't recognize the place you were in. And a stranger was sitting next to you.

Looking down, you saw that you were missing one of your legs! There were only bandages there. You screamed. And the stranger said that he was the one who did it.

You don't remember how it happened. You don't remember this place or this person.

Your last memory is of simply going outside for a walk.

Could it be that a maniac has kidnapped you?
