Victorian Undead

In 1854, a meteor streaked across London's skies, bringing with it a zombie plague. For twenty years, Her Majesty's Secret Service kept the threat under control. But now dastardly fiend Moriarty has begun using the zombies in an attempt to overthrow the Victorian Government. Sherlock Holmes and Dr. Watson must face off against their favorite foe, MI-5 and zombies at the same time.
