 Also, when the player loses a ship on a stage, it is returned to the 'check point' (not identify in game) of that stage, if the ship has lost during a boss also return the last 'check point' before the boss appear.Like "Darius Twin", the player uses (by default) the Y button for shot and the B button for dropping bombs.As long as the player keeps pressed both buttons, the shots are powered down one level.
