Plus Alpha — About this game
Plus Alpha follows two flying heroines through seven occupied countries. Collecting transformation items changes the craft among a propeller plane, a jet and a helicopter, with each form sending its ordinary shot and Hyper attack in a different pattern. Enemies can leave further power-ups along the route, and a boss guards the end of each stage. Unused Hyper attacks also provide attempts at the present game between stages, creating a reason to consider how many to spend during the battle.
