Space Harrier © 1991 Sega Enterprises, Limited.
Not surprisingly, Sega decided to release a version of Space Harrier for their new (at the time) portable called the Game Gear. The game is VERY similar to the Mark III version. The music is almost identical. Most of the enemies were changed for this version though. They're still similar to their Mark III counterparts, but small things were added such as tubes, moss, changed colors. Some monsters where changed completely, such as the one eyed mammoths.
