weapons, players are also equipped with set number of bombs depending on the ship chosen at the beginning that are fired by pressing the B button, while its firepower can be increased by collecting a hyper bomb upgrade capable of dealing maximum damage against enemies and bosses, the latter of which are fought at the end of each stage in order to progress further through the game. Some of the enemies carry power-up items, which appear as colored orbs and alters between the three main weapons after a certain time period passes that can be picked to increase the firepower of either frontal shots, missiles or rear shots. Enemies will also carry extra bomb stocks and hyper bomb upgrades as well. Items will bounce back after reaching the right edge of the screen, however if they are not picked up after this occurs, items will be gone permanently once they have reached the left edge of the screen including 1UP icons, which are spawned after reaching a determined score threshold. Another noteworthy aspect of the title is the scoring system, which allow players to obtain additional points for shooting solid objects from the stages, as well as indestructible parts of large enemies and bosses. Getting hit by enemy fire or colliding against solid stage obstacles will result in losing a live, as well as a penalty of decreasing the ship's weapons to one level and once all lives are lost, the game is over unless the player insert more credits into the arcade machine to continue playing.
