The "Big Guns" pinball machine, released by Williams in October 1987, blends a medieval theme with outer space elements. Designed by Mark Ritchie, this game features an engaging storyline where players must rescue a queen from King Tyrant and his warlords. The machine is known for its tall backbox and unique playfield, which includes four flippers, a pachinko-style bagatelle in the backbox, and two ball-shooting guns on the playfield.
