Shadow of the Comet is an adventure game based on H. P. Lovecraft's Cthulhu Mythos and uses many elements from Lovecraft's The Dunwich Horror and The Shadow Over Innsmouth. The game takes place in 1910, and concerns the visit of a young British photographer, John Parker, to the isolated New England town of Illsmouth to witness and photograph the passage of Halley's Comet.
