Space Harrier II is the sequel to Space Harrier, developed and published by Sega. First released on October 29, 1988, it was one of the original launch titles released for the Mega Drive in Japan and one of the six Sega Genesis launch titles in the United States the following year. It was also later released on the Wii's Virtual Console in December 2006, and on the Nintendo Switch Online + Expansion Pack in April 2022. Like Altered Beast, another launch title for the Mega Drive, Space Harrier II features digitized human voice recordings during gameplay, and is also an example of some of the Mega Drive's early sound, composed by Tokuhiko Uwabo (credited as "Bo"). A graphically enhanced version included with the Sega Genesis Mini 2 was released October 2022.
