In The Krion Conquest, you assume the role of a sorceress named Francesca as she attempts to drive away the Krions who have conquered Earth. Through all five rounds of the game (each with three stages), you'll use your six types of magic to destroy the enemies impeding your way to your ultimate goal, the Krion space station. Holding down the shoot button for an extended amount of time will enable you shots of up to four times the strength of a normal one.
