The Lord of the Rings: The Return of the King Cheats

Reduce your ranged attack meter to 10, and hold Y to charge up a devastating attack right before an in-level cutscene occurs. When it is over, you can use your devastating attack over and over again(if you use a ranged attack, the effect stops).

Go to multiplayer with a friend. Have one of you do a bane move on any enemy. Then the other shoot the enemy who's being killed with the long range attack. If the shooter kills the enemy before the bane move is over, both players will gain experience from the kill!
