Instructions
Take cover behind the columns and stone debris to avoid the colossus' shots. When the coast is clear, jump into the hole on the right side of the area. This leads to an underground bunker.
Run through the bunker and climb out the other side. Hide behind the stone shields to avoid the colossus' shots. Run to the right and into the next bunker.
Run through the second bunker and come out the other side. Climb the rock ledge and shimmy around. Jump across to the ledge and follow it to a tunnel entrance. Follow the tunnel until you emerge to another set of stone shields.
Hide behind the stone shields to avoid the colossus' shots as you run to the right. Keep running until you reach the entrance to the last bunker. Jump and run through, emerging at the feet of the colossus.
Climb the walls and ledges until you reach the top, behind the colossus.
Climb the furry patch on the colossus' back and stab the glowing area. This will cause the colossus to bring its hand back to the wound. When it does, jump and grab the fur on the colossus' palm. This will cause the colossus to bring its hand back around to the front.
Climb the back of the colossus' hand as it swings around. When the hand stops moving, run up the arm to the biceps. There is another glowing area there. Stab it with your sword. The wound will cause the colossus to bring its other hand toward you.
Jump across and grab the colossus' hand. Climb up as before, then stab the back of the colossus' hand to get it to stop moving. Quickly stand up and fire your bow at the colossus' left shoulder. It will bring its hand over to the new wound.
Jump off the colossus' hand onto its shoulder. There is a stone platform on the colossus' upper back. Use this area to refill your stamina before your final assault.
Jump onto the colossus' head and climb to the glowing area. Stab the colossus repeatedly until it falls. It will take nine or 10 strikes.
