When the battle first starts, notice the VS will fly around, doing various little spinning attacks. Fly towards him. While doing this, do a horizontal slash). This takes a rather sufficient amount of health from the Boss. Upon doing this occasionally you can also score a second hit, but be cautious of the homing missiles. The Boss will dart around shooting little lasers at you. This is easily avoidable; simply follow in his direction to miss the attack totally. Be aware, when the boss reaches around 30% health it will call up two laser weapons. These will do massive damage if they hit you. One is horizontal, and the other is vertical. Notice when he gets ready for this attack that he will throw his arms forward. This is your cue to get as far back as possible. The range on the lasers are fairly weak. When he is done, he will stand still for a brief moment and shoot missiles from his shoulders. Usually this is your cue to go in; the choice is yours to do so. The Boss does not have much of a pattern. About nine well placed slashes are required to defeat the Boss.
