Descpription:
Taito has released several arcade sequels that built upon
the basic design of the original. The first was Space Invaders Part II in 1980;
it featured color graphics and new gameplay elements. This version was released
in the United States as Deluxe Space Invaders (also known as Space Invaders Deluxe),
but featured a different graphical color scheme and a lunar-city background.
Another arcade sequel, titled Space Invaders II, was released exclusively in the
United States. It was in a cocktail-table format and featured a competitive two-player mode.
