Descent: FreeSpace – The Great War, known as Conflict: FreeSpace – The Great War in Europe, is a 1998 space combat simulation IBM PC compatible computer game developed by Volition, when it was split off from Parallax Software, and published by Interplay Productions. In 2001, it was ported to the Amiga platform as FreeSpace: The Great War by Hyperion Entertainment. The game places players in the role of a human pilot, who operates in several classes of starfighter and combats against opposing forces, either human or alien, in various space-faring environments, such as in orbit above a planet or within an asteroid belt. The story of the game's single player campaign focuses on a war in the 24th century between two factions, one human and the other alien, that is interrupted in its fourteenth year by the arrival of an enigmatic and militant alien race, whose genocidal advance forces the two sides into a ceasefire in order to work together to halt the threat.
