On the original three-buttoned arcade cabinet, each button fired a different weapon, with three more accessed by pushing two at once. Pressing all three together triggered the 'Radiant Sword' which moved behind you. This could absorb pink bullets, until it was sufficiently charged to unleash the game's only 'special' attack - the Hyper Sword. On the Saturn version, there's a button for each one, but the effect is the same. You're spoilt for choice. Check out the video to see them all in action.
Above: You're spoilt for choice, yet every single one is useful. It's all carefully considered - nothing's in just for the sake of it
