Space Harrier II is the sequel to Space Harrier. It was one of the original launch titles released for the Sega Mega Drive in Japan and the United States and later released on the Virtual Console. Like Altered Beast, another launch title for the Mega Drive, Space Harrier II features digitized human voice recordings during the game play, and is also an example of some of Sega's early sound, composed by Tokuhiko Uwabo (credited as "Bo").
In the year 6236, Harrier once again receives a call for help, this time from the 214th sector, light-years from his cruiser. Harrier travels there quickly with his "cosmic gate", and finds that Fantasy Land is in overrun by hostile forces. He resolves to once again save a world by fighting off the entire force himself.
