Gradius II retains the selection bar from Gradius, but now the player can choose between four different weapon configurations and progressions. All schemes have speed-up and multiples (Options), but have differing 'Missile', 'Double' (laser), and 'Laser' weapons. The player can have at most four multiples. Additionally, there are also two types of shielding to choose from: shield and forcefield. (wikipedia.org)
