· Start With More Lives - This works best if you have a control pad with auto-fire or the attachment. At the beginning of the game, kill the first ninja that comes towards you, and then stand in front of the tree to the right of the screen and fire continuously at it (for several minutes). Now, go through the level as normal and kill the boss. At the score page that appears when you beat each level appears, there is a part that says HIT RATIO (normally the higher percentage of hits, the higher the score). You should have 0% hit ratio (if it isn’t then you haven’t fired enough shots) and you will receive 999,999 points!
