The Tube

The London underground is a scary place at the best of the times, the enclosed spaces, the dark ominous lighting and the horrific screeches of metal. Well now an underground experiment has got out of control, releasing creatures into London's Tube system, these creatures are hungry for human flesh, they start to terrorise commuters. What is worse, nobody sees these creatures until it's too late. Is there anything worse than a creature you can never truly see? A creature you can't see, in a tight enclosed space.
