Banzai Run is a pinball machine produced by Williams in 1988, and the first machine designed by Pat Lawlor.
It has a multi-playfield design, in which the player can play a vertical game on the machine's backglass in addition to the main playfield.
The concept was patented by Pat Lawlor and Larry DeMar, but due to cost was never used again.
[1] Banzai Run was formerly available as purchasable DLC in The Pinball Arcade until June 30, 2018, when the WMS license expired and had not been renewed.
[2] It was released alongside Black Knight 2000 and Earthshaker!
