Defeating Achille and Demon Queen
This is the hardest fight in the game. It is essential to have the Gold Shield . When you start the fight, run as close as possible to Achille. When he looks like he is going to attack, put up your shield and block him. When you can attack. do a thrust attack. After you hit him he will say "Back off" and a sphere of purple energy will fly out. Do not worry, as this does not hurt you. When you get up, immediately do a double jump then run in for the attack. Once you do another thrust attack on Achille, he will have a big replica that cannot be hit. Do not try to hit this thing -- only repeat what it says on the forcefield guarding Achille . After this, four energy ray guns will appear from the floor. Achille then starts to regain his life. Attack these guns as fast as possible. Try using your shield because it can be used to hit things from a distance. Once this happens three times, Achille's power will run out of his staff and turn it into a brutal weapon. All you have to do at this part is to use thrust attack after thrust attack. Once Achille is gone you will have to fight the Demon Queen. She is very easy. When you fight her, the whole room will be pitch black and all you will be able to see is her eyes. She will approach you. Jump and strike the stone in her forehead to defeat her.

Defeating Captain Cadaver
This is a very easy battle. To defeat him, knock him onto the grates on the floor until he starts to try to get out. Then, kneel (L2) and press Square. This will knock him out of the grate, causing damage. This Boss is not very difficult and only has a few attacks. For most of his attacks, just use your shield to block them. For others, such as when he shoots at you, use timed jumps.

Defeating Ghastly Gus
Do a downward strike (X, X, Triangle) until he falls, then do a thrust strike (hold any direction and press Triangle). Stay out of the hole in the middle of the stage. It is "dead ground" and will slow you down and cause damage. Since Gus is so large, he is rather slow. You can use this to your advantage. When the battle begins, run away from him so that he does not chase and attack you. When he flings boulders, simply run in a curve and they will not hit you. After that, he will smash the ground with his shovel. Perform a double-jump over the shockwave that is created. While he is yelling, perform a downward strike (X, X, Triangle) on his foot. Perform another while he is yelling (this time in pain) to knock him over. Perform a thrust attack. Repeat this to defeat him.

Defeating Lakor Bas
When he shrinks, keep jumping away from him (X, X). After that, he will send out some little voodoo dolls. Hit as many as you can until he starts shooting at you. The best way to destroy these little guys is a spin attack (Square, then rotate the Analog-stick counterclockwise). After that, he will split up and start running around. Hit all of them until there is one remaining. Then, do a thrust strike (hold any direction and press Triangle). Repeat this and you will be victorious.

Defeating Lord Gutterscum
This is the easiest Boss in the game, Make sure you go into the battle with Armageddon (the purple sword power-up). When he stops moving, run around him and hit him in his fanny with a thrust attack. Repeat this and he will be defeated. This fight is easy because he just stays in one location -- it just requires timed jumps.
