Wing Commander: Prophecy is the fourth direct sequel in Chris Roberts' Wing Commander science fiction space combat simulator franchise of computer games. The game was released in 1997, produced by Origin Systems and distributed by Electronic Arts.
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.
A standalone expansion pack, Secret Operations, was released by Origin in 1998 solely over the Internet and for no charge. The large initial file challenged the dial-up connections of that day. Secret Operations was later released for sale in combination with Prophecy in the Wing Commander: Prophecy - Gold package. A Game Boy Advance port of Prophecy with added multiplayer was released in 2003. Also, a number of fan-made mods based on the game's engine has been developed and distributed.
It has been some twelve years since the destruction of Kilrah, the Kilrathi homeworld. The Terran Confederation, slowly demobilizing and reorganizing its military assets, has settled on a new strategy: building several Midway-class megacarriers, brainchild of Navy Commodore Christopher Blair. These new carriers, over a kilometer long, carry all the hardware and weaponry of a Kilrathi-War-era carrier battle group. The first one, the Midway herself, is undergoing her shakedown cruise, with Blair along for the ride. Before this, though, the player is treated to a CGI video of a bizarre rupture in space in the Kilrah system: the first of the Nephilim invaders. The game's titular prophecy involves the coming of these alien invaders, who shall arrive only after "one who has the heart of a Kilrathi, but who is not Kilrathi-born," conquers the felinoid warrior race.
