Wing Commander is the first game in Chris Roberts' space flight simulation Wing Commander franchise by Origin Systems. The game was first released for MS-DOS on September 26, 1990 and was later ported to the Amiga, CD32 (256-color), Sega CD and the Super Nintendo Entertainment System, and re-released for the PC as Wing Commander I in 1994. An enhanced remake Super Wing Commander was made for the 3DO in 1994, and later ported to the Macintosh. Wing Commander is a space flight simulation game, with the player piloting a ship, completing missions, and engaging enemy ships of various capabilities. As the title suggests, there will generally be an AI-controlled wingman which the player can give orders to. Missions will generally include multiple objectives, but the game can proceed even if objectives are failed as long as the protagonist survives. The game features a branching, open-ended story where overall performance affects the campaign: succeeding at objectives results in medals, promotions in rank, and progressing to missions with better ships; failing at objectives leads to more difficult missions and piloting inferior ships. The mission tree is designed so players on the "losing" path could work their way back to the "winning" path, and conversely players on the "winning" path could fail subsequent missions to fall into the "losing" path. In addition, the wingmen can be killed permanently in combat, and thus be gone for the rest of the campaign. Two expansion packs for the game were released: Wing Commander: The Secret Missions in November 1990 and Wing Commander: The Secret Missions 2: Crusade in March 1991.
