Aqua Prophecy is a cancelled action adventure game that was in development by ASCII for the Playstation. The project was shown at E3 1997, but sadly it was never finished for some reasons. More info about this game can be found on IGN in an old interview / chat with Rob Fleischer from Ascii:
Adam@PSXPower: Tell us about Aqua Prophecy.
Rob@ASCII: Aqua Prophecy is an underwater adventure where you are out to save the world. You must save the world from the prophecy of Nostradamus and you travel to various different underwater locals.
Dinosaur: “Like Tomb Raider, only all under water?”
Rob@ASCII: Kind of, Dino.
Spelunx: “Is it like Ecco for Genesis?”
Rob@ASCII: There is a lot of puzzle solving and not a lot of killing. You explore sunken pyramids, ships, planes.
Bizarro: “Have you been researching the Nostradamus prophecies for the game?”
Rob@ASCII: Yes, it is true to form.
As with another cancelled aquatic game, Aqua by Scavenger, Aqua Prophecy’s gameplay could have been similar to Everblue (PS2) / Endless Ocean (Wii) by Arika or the Aquanaut’s Holiday series by Artdink.
