This is an update/sequel to the smash hit Space Invaders.
This game is notable for introducing the concept of a cut-scene, which appears during an interlude between the gameplay.
Taito's original Japanese release, Space Invaders Part II, used a color monitor supporting RGB and a color generator board producing 8 colors on screen. Midway's North American version replaced the RGB monitor with a simple color overlay.
A version with increased difficulty which gave out money prizes for performance called "Prize Space Invaders" was released in 1990.
