How do you beat the challenge of hades on god of war 1

There are several parts of the challenge, for the first, I believe you must then fight a group of centaurs, kill them in both of the two circles of hades till the door on the cliffs opens then the maze, kill all the enemies in the maze and find your way into the room with the statue of hades, go under the water that the statue is in and pull the lever. surface and point the light at the top of the statue into the dark room you opened up. A bunch of fireballs will come your way so dodge them until you get to the third door on the left (be quick), time it right and open it up to go through. The next part is a series of mazes you can easily navigate until you get to the boss battle. The boss is easy, but it takes a long time for me maybe because I played it on God difficulty. Yeah, just remember to jump before he hits the platform. After that run to the cracked door and up the stairs, then stael the architechs son's head, go learn a powerful move and make your way to the rings of pandora. Then on to the higher levels of pandora's temple...
