god of war 3 in the labyrinth how do you kill the spider?

After you break one side, i think an O comes up above the spider and you have to get in front of its face and push it and push whatever buttons it says. Then you can go to the other side and do the same thing. Go to gamespy.com and search for god of war 3. Theres a good walkthrough on it that helps with everything.

You need to use the Cestus to break one side of the legs. When the onyx isn't there anymore, you need to get to the spider's face and hit it with everything that you have. Then the O button will pop up, and then the button pressing thing begins. The spider will disappear, so now is the time to kill those little spiders and replenish your life. Press O to attack the little spiders. The big spider will once again pop up, so once again, take out one side of its legs. When it's down, attack the head, press the O button, press a sequence of buttons, then you'll get thrown off the spider. Get ready to dodge some ice spikes and be ready to hit some buttons. The spider will become frozen so you need to attack it to break it. Then you'll get the ice crystal that you need to power up some machinery.
