Star Wars: X-Wing vs. TIE Fighter is a 1997 space combat game developed by Totally Games for LucasArts. It is the third installment of the X-Wing series. Featuring several technical advancements over the original releases of its predecessors, X-Wing vs. TIE Fighter runs on Windows, requires a joystick, features a CD audio soundtrack, supports high-resolution graphics, and brings texture mapping to the ship models of the in-flight game engine. It includes robust multiplayer options for up to eight players in free-for-all, team-based, and cooperative play modes, and has a sophisticated pilot and mission selection system that tracks the player's points and awards. In addition to selecting what craft they will fly, the player can choose their squadron (and thus role in combat) for each mission. While all content could be played single-player, it is the only part of the series designed primarily for multiplayer, and it lacked a story-driven campaign. LucasArts later released an expansion called Balance of Power to satisfy popular demand for story-driven campaigns, and to further expand on the multiplayer features.
