You can defeat a lot of the Orcs before you enter the next area. For example, after you burn the spider web and go through it, you will see an Orc meeting at the end of the tunnel. Go back to the torches and pick one up. Even though you cannot see far ahead, throw it in that direction. Amazingly, you will strike every time. You can clear up the room before you even enter it. Just throw the torch and you will hear the "hit" sound. This will also work with the archers in the left tunnel ahead. Fire will be useful if you use it to clear your way ahead, even if you cannot see your enemy. It seems that Sam has great aim.
