Lorelei Shannon is an American writer of horror and computer games.
Shannon is the author of a number of books and short stories. Her work has been listed in The Supernatural Index: A Listing of Fantasy, Supernatural, Occult, Weird, and Horror Anthologies, by Mike Ashley and William G. Contento. She co-edited the anthology Hours of Darkness for Scorpius Digital Publishing, which contained stories by well-known horror authors such as Ramsey Campbell, Peter Crowther, Dennis Etchison, Joe R. Lansdale, and Richard Christian Matheson.
She is a designer and screenwriter for three games from Sierra On-Line. Shannon co-designed King's Quest VII, a 1994 installment in Sierra Entertainment's King's Quest computer game series, with Sierra founder Roberta Williams. Shannon's sequel to Roberta Williams's horror game Phantasmagoria, called Phantasmagoria: A Puzzle of Flesh, caused a storm of controversy when it was banned in Singapore and Australia for violent and sexual content. Sears stores throughout the U.S. refused to carry the game.
