You suddenly find yourself conscious. You're standing in a line in what appears to be a trainstation. You're wearing an odd blue uniform, and a silver dogtag is around your neck. You're at the back of the line. In front of you are a bald man and a tall, black haired woman. Both of them are wearing similar uniforms. You appear to be lining up at a door in a chain link fence. In the doorway stands a menacing figure, a man in an armoured suit, and what appears to be a gasmask. He's carrying a hefty submachine gun.
