X-Wing is a space combat simulation, the first in the Star Wars universe. From the cockpits of X-Wing, Y-Wing and A-Wing starfighters, players fight for the Rebel Alliance in their struggle against the evil Galactic Empire. Unlike earlier titles in the genre like Wing Commander, X-Wing employs a polygonal 3D engine: flat-shaded polygons are combined with bitmaps only for explosion effects.
The main part of the game consists of three separate campaigns, called Tours of Duty. The Tours can be played in any order, even though they build on each other story-wise: Tour I, 'A New Ally', tells of the Rebellion's search for political allies in their fight against the Empire, while the Emperor launches Operation Strike Fear, a major offensive against the Rebels. Tour II, 'The Great Search' chronicles the Rebels' search for the plans to the Empire's new superweapon, the Death Star. Tour III, 'The Gathering Storm', tells of their efforts to find and destroy the battle station. Animated cutscenes are featured after certain missions to continue the story.
Each Tour consists of around a dozen missions, which include a wide variety of objectives. There are standard strike, escort and defense assignments, but also reconnaissance flights - just scanning ships without attacking them - or capture operations - disabling enemy ships, then protecting the transport carrying the strike team during the takeover. The game of course culminates in the famous attack on the Death Star.
