"Invader Ball" is a solid-state pinball machine produced by Red Baron Amusements in 1980. This game uniquely combines traditional pinball elements with a video game component, featuring a monitor behind the backglass that displays a "Space Invaders"-style game. The playfield design mirrors that of Gottlieb's 1980 "Buck Rogers" pinball machine, incorporating two flippers, two pop bumpers, a four-bank drop target, two two-bank drop targets, a kick-out hole, and a messenger ball.
