You play a defect - a human form that has formed within an all controlling A.I. While the defect police is after you, your humanlike Alter Ego transforms through several stages of a human being.

The player must attempt to hack into the Magma Ltd. computer system at the beginning of the game by guessing the logon password.

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". Fifty years later, in 2047 (2042 in the Japanese versions), 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. Nobody knows exactly what they are or where they come from. 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. The story takes place in three acts.
