Alone in the Dark is a 1992 survival horror video game designed by Frédérick Raynal. Developed and published by Infogrames in 1992 for MS-DOS, the game was eventually ported to Mac OS, the PC-98, the FM Towns, the 3DO, RISC OS, and iOS. Alone in the Dark is set in 1920s Louisiana and challenges the player to escape a haunted mansion. To advance, the player must solve puzzles while banishing, slaying, or eluding various ghosts and monsters. The player can collect and use weapons, manage a weight-based inventory system, and explore a partially nonlinear map.
