When you get to the part where you have to kill 75 Orcs, stay on the ridge and let the ents kill them then move on.

To easily defeat Shelob, make sure that you have the move "Poison Blade" before entering this level. Charge the move up when Shelob backs away, then strike when she approaches. This will make the battle go much faster.

Use Legolas and run directly up to Shelob. Start using your speed attack. She will turn around, but keep slashing. Her health will drop dramatically.

When the battle starts, Shelob is preoccupied with Frodo, so you can get a free hit on her. Use this to your advantage and attack with the Orc Hewer combo, This is recommended, as using a 4-hit combo will end up with you damaged. She will start hitting you three times in a row. Parry those hits, then respond with a simple Speed combo. Do not bother with other combos (even Orc Hewer), because trading blows with Shelob is tricky; she will strike quickly then pause, but the lull is only long enough to get a very quick combo in. Orc Hewer is slower to develop. Keep trading hits (remember to parry as well) then, after enough damage, you will succeed in putting out one of Shelob's eyes. Shelob will crawl up the wall and summon some spiders. They will drop from the sky. When you see one of them flying down, go to where it will land and start using Final Judgement to kill it. Then, run to one of the walls. If one of the spiders does not follow you, use a ranged attack to get its attention. Then, on the spider, use a Fierce attack, then the Death move to kill it. Repeat this with all of the spiders. Do this quickly, as if you take too long Shelob will jump from the wall and you will need to deal with her and the other spiders as well. When Shelob jumps down, she will be flat for a few seconds; use another Speed combo. Then, she will trade blows with you again. If you do not damage her enough, she will call more spiders. Damage her quickly. If you hurt her enough, you will cut off half of her leg. She will then run around her lair and try to run you over. You cannot parry this; run away. She will then call more spiders. Repeat the same process. She will then trade blows with you; repeat again. Repeat this entire process until she is dead.

Press Triangle to knock the spider over, then press R2 to kill them. This is useful when fighting Shelob.

At the very beginning of the level, when you walk up to the gate a Troll will drop down. In co-op mode, have one person near the pikes and have the other player walk up the gate. When the troll comes down, have the person by the pikes press Action and throw the pike at the Troll. It will be killed automatically. This helps save health.

Use the following trick to defeat the Troll at the top of the walkway. When you run up the ladder, do not go up all the way on the platform with the Troll. Stand behind the small wall and use a ranged attack. The Troll cannot reach you, though he will swing at you. The Orcs and other enemies cannot get past him and also cannot hurt you. It takes a few shot to bring down the Troll, but you will not be injured.
