Wing Commander II: Vengeance of the Kilrathi is the first sequel in Chris Roberts' Wing Commander science fiction space combat simulator franchise of computer games, produced by Origin Systems.Released in 1991, Wing Commander II retains much of the first game's core conventions: an interstellar war between the Terran Confederation and the felinoid warrior race called the Kilrathi, multiple allies as wingmen, and a wide variety of ships on both sides of the war. However, WCII places a greater emphasis on storytelling, providing various sprite-animated cutscenes and some of the industry's first examples of voice acting.
