This isn't a cheat or anything but it's a funny glitch. Go to Co-op mode with a friend.Choose Aragorn or Legolas.Your friend can choose whoever they feel like.Now go to "Paths of the Dead". Fight your way through.Kill the huge army at the end.Now,run to the exit.BUT DO NOT GO THROUGH YET! You must charge your arrow up to the full extent.Now tell your partner to run to the exit.When they are about there shoot your arrow. It will go to the cut-scene and your arrow will be flying by!
