How To Beat Him: It was MC Hammer that once said, "We have to pray just to make it today." And while prayer is a rather useless ability for the entire length of the game, it's the only way to defeat Giygas. Added creepy bonus: It's a widely held belief that Giygas is a fetus and that he represents rape. Fun!
