Ring Heroes:
Every map in skirmish or multi-player mode has Gollum cloaked on it. After finding Gollum, kill him and you will get the ring. Take it back to your fortress and have the troop that is carrying the ring enter the fortress in order to recruit a Ring Hero for 9,000 resources. Your Ring Hero uses no command points. Men, Elves, and Dwarves can recruit Galadriel. Mordor, Isengard, and Goblins can recruit Sauron. The easiest way to get the ring is to let an enemy find Gollum then kill them after they acquire the ring. The only way to stop them before they reach their base is to chase them down with a mounted unit, have a created hero teleport into their path, or to summon allies into their path using a power.

Defeating groups of enemies:

-Have plenty of defensive structures in your base and teleport the opponents to your base. The towers will kill the enemies before they can do much damage. The Convert spell will also work, because they are free men.

-This strategy works best with the elves. To kill armies (including brutal) easily, first get as many Mirkwoods as possible. Have them guard your fortress and make sure they get Silverthorn Arrows. After that, get Glorfindel and Arwen and three to five groups of horses. Upgrade them fully and then send them around the back of the enemy base. Have them attack. This will work almost every time. Make sure that Glorfindel and Arwen are on their horses. It also helps to have Rally Call and Heal.

-Use the following tactic on the Minis Tirith, Minis Morgul, Helm’s Deep, or Isengard maps. Build your army and close the gate, then place three battalions of Archers on the walls of both sides of the gate. When the enemy starts attacking, kill them. You can open and close your gate rapidly from time to time to taunt them. When you open the gate they will try to enter but your archers should take care of them.

Easy experience:
To level your race up in Skirmish mode quickly, create a hero that can learn the Recruit Battlions power. Set up a game against an easy AI with a handicap of -95%. As soon as the game starts, create your hero and rush into the enemy’s. Use the power to summon a battalion and the skirmish will be over in two minutes.

Grey Havens:
Start at the bottom-most part and build as many resource collectors as possible. Then, capture the Shipright and get Builders to build Wall Hubs where the Cave Trolls lair is found (kill it first). Build a wall. Now build units and an upgrade structure. Get your units upgraded as much as possible. Put some by the wall to defend it. Send the rest to the Shipright. Build the number of transports needed. Put the units by the Shipright onto the transports. Send the transports to the enemy camp. Optionally, split your units up and surround the camp. Destroy all the structures except for the fortress. Finally, destroy the fortress.

The Shire:
On the third level of the Evil campaign is a mission where you must capture the Shire. This mission is very easy up to a point. Play the mission until you must build a base in the Eastfarthing, then build a base with two of each building (including Fortresses). Also, build at least ten Sentry Towers. Upgrade your Fortress to the maximum and build all your Fortress expansions as Mountain Giants. Stay in your base and repel all Dunedain attacks until you have killed all them all. You will be notified when all Dunedain have perished. When you reach the part where you must destroy the three remaining Seats of Power, only send one Goblin horde to destroy them, as there is literally no resistance with the Dunedain defeated. Do not destroy the Seat of Power in the bottom-left corner of the mini-map. At this point, build a large army with at least 750 command points available. Purchase all available upgrades for your Goblins. Send all your units to the large, grassy field at the bottom-left corner of the mini-map, just south of the last remaining Seat of Power. Destroy the final remaining Seat of Power with as little units as possible, then retreat a short distance to the north. You must do this because a volley of arrows will kill many goblins if you remain in that grassy field. After a couple seconds, immediately return to the grassy field and a large army from Isengard will emerge, led by Grima Wormtoungue. Fight this army until only two Goblin hordes remain in your forces. Send these troops to your base, and build as many Goblin hordes as quickly as possible. In a very short time the army will attack your base. Do not try to defend any other buildings besides one Goblin cave and your Fortress. Uruk-Hai will lay waste to your forces in a short time, but your fully upgraded fortress should hold them back while you construct more Goblin hordes. After some relentless Uruk-Hai attacks, the flow of enemies should stop. At this time, re-build your base and construct a large army. Lead this army into the Isengard base and kill Grima. This part of the level is very difficult, as the Ballista will quickly destroy your units. Destroying the Ballista first is recommended.

Postern Gates:
When building a wall around your base in Skirmish mode, never put in gates. Always put in Postern Gates. A Postern Gate is a small door in a wall that lets allies pass through, but not enemies. It is invisible to the enemy, making passing through a wall virtually undetectable, and allies can pass through a Postern Gates as fast as they would pass through a regular gate.

General strategies:
-Avoid rushing your opponent’s territory. Either send in a camo capable unit or a very cheap, weak unit such as Orc Warriers. Scope out your opponent’s base before attacking with stronger units

-When attacking, use melee soldiers so attack buildings and use Calvary and Bowmen on enemy units.

Hero power transfer:
Use the following trick to give a hero any power(s) desired, but it requires plenty of time and quite a few patience. First, make a hero with no powers then a second hero with the power desired (for example, an elf hero with Healing). Then, stack them together on the playfield. Click on the hero with the single power. Go to the “Powers” menu. When you click “Customize”, quickly press the quick switch key to your hero with no powers. When you enter the powers menu, the “hero” using the powers from the power menu will be the hero with no powers. After that, click on the blank unit portrait (the picture of power will not be there) where the desired power is located and re-select it. You can now make other heroes with the desired powers you want and put them on your new glitched hero. Note: You cannot “pull” multiple powers from the valid hero unit; you will still need to add them one by one to the glitched unit.

Invincible Troll glitch:
Kill a Troll while it is barely coming out of the Troll Cage. It will be invincible, freeze where it is, and you will still be able to shoot at it. You can still gain power points from shooting it. Eventually, it will unfreeze and attack any enemies.

Unlimited health for elves:
Make an elf hero with self-heal. You can get no recharge time on it. When you want to click on it, do so but quickly move to another location. It will not recharge. You can do this as many times as desired.

Reveal entire map permanently on Dol Guldur:
First, you must have played the map in Skirmish mode to get the hang of it. Play it at least three times and memorize the locations. When you start the level in the Good campaign, you must have the Tom Bombadil power and Elrond’s Farsight power. Use Elrond’s power and eyeball the Dark Shroud to find the center section of Dol Guldur (the part with the fortress in it). Note: You can see the texture of the terrain as you move the the Farsight power’s pointer. Once you have successfully revealed the fortress area, summon Tom Bombadil just in front of the fortress. Once he is in, the shroud should disappear permanently with no fog of war. You can see exactly what the enemy is doing at the moment. You can use Bombard, Flood, Earthquake, or Sunlight, to attack enemy units and buildings, and when they are weakened, launch the assault with your army.
