Snatcher is a cyberpunk-themed graphic adventure produced by Konami, originally released in Japan for the NEC PC-8801 and MSX2 in 1988. It was followed by a CD-ROM-based remake released for the PC Engine in 1992, which was subsequently ported and localized into English for the Sega-CD in 1994. On June 6, 1996, a biological weapon known as Lucifer-Alpha under development in Chernoton, Russia, is released into the atmosphere, resulting in the death of 80% of the Eurasian population which in turn results in the death of half of the world's population. The contaminated area becomes uninhabitable for a decade when Lucifer-Alpha mutates into a non-lethal form. This tragic event later becomes known as "the Catastrophe". 51 years later, a breed of artificial life-forms or bioroids known as "snatchers" began appearing in the artificial island of Neo Kobe City, killing their victims and taking their place in society. As Gillian Seed, an amnesiac working for an Anti-Snatcher task force called J.U.N.K.E.R., the player's goal is to track down the source of the snatchers and discover Gillian's mysterious connections with them.
