Space Odyssey (スペース オデッセイ) is an arcade game released by Sega for Sega G80 hardware in 1981. It is an early 2D shoot-'em-up with both horizontal side-scrolling and vertical scrolling segments (later popularised by Konami's 1986 hit, Salamander/Life Force).
Space Odyssey was distributed in upright, "mini" and cocktail cabinets.
