T.T Space Invaders © 1978 Taito.
For more information about the game itself, please see the Taito upright version entry.
This Japanese cocktail version was released in July 1978. It comes in three different color variations: monochrome (black and white), color (identical to "Space Invaders Part II"), and cellophane. All three of these variations (plus the upright version, complete with the moon backdrop) are showcased as separate options in later compilation releases including "Space Invaders DX" and "Space Invaders Anniversary", plus various home conversions.
