Wing Commander: Prophecy is the fifth installment in the Wing Commander science fiction space combat simulator franchise of computer games. The game was originally released in 1997 for Windows produced by Origin Systems and distributed by Electronic Arts and in 2003 a GBA conversion was produced by Italy-based Raylight Studios and distributed by Destination Software. The game features a new game engine (the VISION Engine) new spacecraft characters and story elements. The events depicted in Prophecy are set over a decade after Wing Commander IV: The Price of Freedom and rather than the Kilrathi the player must deal with a new alien threat an insectoid race codenamed Nephilim that has invaded the human galaxy through a wormhole. Prophecy was the first main-line Wing Commander game in which the player did not take on the role of Christopher Blair instead being introduced to a new player character Lance Casey. Some of the characters and actors from previous games return in Prophecy where they rub elbows with an entirely new cast of Confederation pilots and personnel.
