Ghost Hunters is an platform/action game written by the Oliver twins for the Amstrad CPC and ZX Spectrum platforms and published by Codemasters in February 1986. The game combined platform-style action with shooting gameplay similar to that found in the game Operation Wolf. The game is the second release by the Oliver twins, published when they were just seventeen years old and still going to school. It was conceived as a sequel to their first commercially-successful game, Super Robin Hood, although it has little to do with this game other than using a modified version of its engine. The game is arguably an early example of the survival horror genre of computer games. The twins have credited the film Ghostbusters and the cartoon series Scooby Doo for influencing the game.
