must scale the walls until you jump off and onto the giant. It will try to reach for you,
but stay calm and wait. As soon as you hit the eyes, You must becareful of its rampage, It
charges at you and swings randomly and is most likely to hit you. Once he is on the
ground, jump on his back for the final blow.

Good luck dude.
