After being jolted awake by a tone over the airplane's PA system and a friendly conversation with a fellow passenger named David, a group of terrorists, who seem to be guided by some kind of mysterious cultist chanting to himself, suddenly and violently takes control of the plane.

David, who turns out to be a special agent within the FBI, attempts to stop the terrorists, but he is thwarted when a meteorite strikes the plane, sending it crashing into the Canadian wilderness.

After a series of bad dreams, Laura awakens in a small cabin being cared for by Kimberly Fox, a poet, and songwriter who also survived the crash.

She is driven deeper into the mystery when she must venture into an abandoned mining facility in order to locate Jannie, a lost little girl Kimberly had found along with Laura and one of the plane's former passengers.

The player would have taken the role of Laura's son as he enters adulthood, and must escape a large castle and fight the Devil to save his father.

[4] Unlike the original D, but like the D2 that was released for Dreamcast, the game was to feature full-motion video cutscenes but gameplay entirely played out with real-time graphics, and consisting of both puzzle solving and combat.

[6] For Christmas that same year, Warp sent out D2 brand packets of curry emblazoned with the images of Kenji Eno and Laura to select journalists.

[7] Though at the time it was believed that D2 was nearly complete when Panasonic officially announced that the M2 was not going to be released,[8] Eno later revealed the game was "about 50 percent finished".

[2] In Japan, a demonstration version of D2 was packaged with another Warp-produced game, the Dreamcast remake of the Sega Saturn title Real Sound: Kaze no Regret.

Additionally, it contains a save file that copies to the Dreamcast VMU and unlocks a "secret movie" in the retail Japanese version of D2.
