From Wikipedia Space Harrier (スペースハリアー?) is a rail shooter game, released by Sega in 1985. It was produced by Yu Suzuki, the man responsible for many popular Sega games. It spawned several sequels: Space Harrier 3-D (1988), Space Harrier II (1988), and the spin-off Planet Harriers (2001). Space Harrier was originally made for the arcades, and later saw ports to many home game systems. Space Harrier's release on the Sega Master System is notable: there were two versions. One was just like the arcade, while the other, entitled Space Harrier 3-D was actually a sequel.
