Necronomicon (ネクロノミコン) is an adult-themed, horror-adventure game set in the town of Arkham in H. P. Lovecraft's fictional world. The story included Deep Ones and hybrid spawn-folk. Fairytale (Hardcover) was the publisher.
The game was released on the NEC PC-9801 and the Fujitsu FM Towns Japan-market computers in 1994.
The FM Towns version of the game included a CDDA orchestral soundtrack; some tracks with synthesized "horror" effects and opera-style singing.
