After you defeat the King of the Dead, you have to run back through the level as the whole place comes down on your head. When you get to the white mists that really slow you down, try facing the opposite direction and jump backwards. This lets you get through the mist faster.

After you defeat the King Of The Dead and must run through the mist, most characters will die when the second groups of rocks fall. To get past this, enable the "Play as Faramir" code. He is faster than the other three characters. Note: Do not stop running.

If you get lost while escaping the level, find the rats and follow them. They will lead you to the end.

When you defeat the King Of The Dead, you have to go through blue fog. An easy way to get through the fog qucikly without being smashed is by using the speed attack when you have the four hit combo on. You will take steps twice as fast.

When fighting the King Of The Dead with Aragorn, it is easiest to kill him using the speed attack. Not only can this do a lot of damage fast, but this move will even block some of the King's attacks when you are facing him toe to toe.

When fighting the King Of The Dead, always approach him when you see the green/yellow/red bar above him (depending on how much damage you inflict on him) and parry first. In the beginning he will attack three times (usually with a green bar above him), four times (usually with a yellow bar above him), and five times (usually when a red bar is above him). Timing is also a factor. As a rule, you want him to have a yellow or red damage bar above him by the time he summons "Winds Of The Mountain".

After awhile, the king will set up to use his "Wind Of The Mountain" attack. You will start behind a rock on the very right side of the level. If you go immediately, you can make it to the other rock to the left without taking damage. When the king pauses to recharge, step out from behind the rock. Then, pour on the ranged attack. If you hurry, you can get five shots off each time. If done correctly, you can take out a quarter of his life each time he tries to set up the wind attack. If you have any skill, he will not be able to use his wind more than twice.

When fighting the King Of The Dead and he goes into his wind attacks during that time that your are positioned behind a rock, between attacks, jump out, then fire your range attack repeatedly. Make sure you get behind the rock again before the wind starts. This is most effective when playing as Legolas, as he can fire faster than Gimli or Aragorn. This will prevent you from fighting the dead champions (the dead soldiers with the green bar above their head) later, which saves time and life.

When the King Of The Dead sends out his little minions, run all the way back to where the cliff is located. Once his men appear, they will not see you. Take out your bow and shoot one. He will start to run towards you. Fight him, then repeat. Note: A similar strategy also works at Shelob's Lair.

When playing in co-op mode, have the strongest character fight him while the other person shoots their ranged weapon from a distance. This will quickly wear down his health.

Play as Faramir. Shoot him with the orange . It helps to get Strength Of Stone to make your health stronger.

When at Pelennor Fields, there will be approximately four Oliphaunts (after the sixty Orcs are killed). The first one will come on the side that you are already on. The next one is on the other side. Go down the path provided to the other side. Note: Do not kill any Orcs or warriors. Once you get to the other side, destroy that Oliphaunt. The next one is also on that side. You will know that you are at the correct location if when the Oliphaunt enters, it fires arrows. It will not do this if you are on the wrong side. As for the Nazgul, it should appear two times before it starts taking damage. Fend it off the first two times on the side that you are already on. After the first time an Oliphaunt should also appear on that side. Then, for the second time, the same thing should happen. Finally, go to the other side. The Nazgul will appear vulnerable to ranged attacks. Note: It may go away on the third time; just stay on that side.

On your first trip through, play as Legolas. His archery skill is useful and allows you to become familiar with the level with minimum damage. When taken to the cliff top at the checkpoint, charge to the left to a Mumakil that is going by. Parry for a few seconds, as there are quite a lot of arrows coming in. Take the Mumakil down. Run down the ramp to your right, and wait for the enemy army to pass out of sight. Rush across in as straight a line as you can to the other ramp, ignoring any enemies that come at you. Once you are up the ramp, run to the right. Your companions will usually keep any other Orcs/Easterlings behind you busy, but be on your guard. The Mumakil moves slowly, so you will have time to dispatch a few annoying enemies before it reaches the other end. Once the Mumakil is down, rush to your left as far as you can before the intermission sequence begins. The Witch King is swooping down over Eowyn and Merry. Continue left and use combos and/or Fierce Attacks to bring down the charging Easterling then run as far as you can to the edge of the platform. Shoot frequently, charging when you can, at the Fell Beast. If you are lucky, and your companions keep enemies busy behind you, you can kill the Fell Beast in one session.
When purchasing upgrades, always try to get all of the level upgrades before purchasing the higher level attacks. This is because some attacks require certain level 2 attacks (for example, Ranger Fury).
