Released in June 1981, Embryon was the first Bally game to feature artwork by Tony Ramunni, and the first (and last) game from this company to use the trademarked 'Flipsave' ball saving feature - a small flipper inside the right out-lane used by players to flip lost balls back into the return lane.
