Elliot disguised himself as a zombie to get the sharp shiny sword.

Later he finds a secret entrance to the cave where the ogre is hiding.

He then finds an Ogre and a battle to the death starts.  Clanging metal and screeching blades fill the cave.  The Ogre backs Elliot into a corner and slashes with his sword.  Elliot barely manages to escape.  Elliot swings at the Ogres legs knocking him to the floor, he then plunges the sword in to the Ogres heart.
