At the end of stage six the player will be challenged by two large flying red creatures known in the game as "Satan". While using the shield weapon, allow both "Satans" to swoop over Arthur's head so that they are both on the left side of the player. At this point, immediately run as far to the right as the game will allow then turn around as begin firing as fast as you can. Both Satans will stand directly in front of Arthur unable to use their swoop move, and the shield protects Arthur from incoming projectiles. This strategy leaves the "Satans" immobile, defenseless, and susceptible to defeat in a matter of seconds.
