Shadow of the Colossus has a simple, yet epic story. The hero, who is known simply as Wanderer, travels to this forsaken land to resurrect a loved one. Once in the temple of this forsaken land, a disembodied voice tells him of a way to revive her: to destroy 16 statues along the great hall of the temple. This is a feat that is not easily accomplished, as these statues are invulnerable. The voice tells our hero that in order to destroy these statues, he must defeat 16 colossi counterparts that roam the land.
So our hero has his quest now - he must find these colossi and then defeat them. How does this single person find these colossi, giant as they might be, in this huge world? He has a magic sword that, when held up in the sunlight, uses rays of light to point in the direction of the next colossus. So, using his magical sword and riding his trusty mount Agro, our hero sets off to defeat these 16 colossi.
The colossi are massive creatures that roam the land. Most are confined to small areas that seem like a habitat, of sorts, for these creatures. Others are left to roam vast areas. When one hears the word Colossus or Colossi, they think of giant stone men. While, in some cases, this may be a true description, the colossi in Shadow of the Colossus vary in shape, size and type. Some are quite small, while others are incredibly large. There are ones that can fly, swim, or even just stand still. As different as each colossus is, so is the way to defeat it.
The player must figure out several things for each colossus before even attempting to climb onto it, much less defeat it. He must figure out where the weak spot or spots are on each colossus (done by holding your sword in the sunlight and pointing it at the colossus), figure out where to get on the colossus and then how to get to the weak spot from there. All these tasks combined make each colossus a unique encounter that is exciting and fun. Figuring out how to climb onto each colossus and then getting to their weak spot can sometimes be a very frustrating and difficult thing to do, but this makes slaying each all the more satisfying in the end.
