Press Enter and enter the following codes:

Complete "The Crossing" Secret Campaign.

Play in Human 3rd Mission. There are 3 sheeps, step onto them in the order "Bah-Ram-You".

Destroy huts, tents, or other homes. Some of them will have hidden items such as Scroll of Town Portals, Potions of Mana, etc. Pick them up for later use.

In the prison mission, you will find various humorously named guards, such as one called Trogdor. It is interesting that he is burninated almost immediately after you see him. Other guards will have names like Seth, Marcus, or Troy.

Get a Demon Hunter with Metamorphosis and use it. Then, enable the thedudeabides code to have the cool down done fast, then click the active Metamorphosis. Your Demon Hunter should turn back to its original form, however instead of "level ##" it will say "Metamorphosis" with the bar going down . When the bar hits zero, your Demon Hunter's attack should hit for 96 to 100 damage.

Take any kind of Night Elf base (Tree Of Ages, Tree Of Eternity, etc.) in multi-player mode and send it to an area where there are a lot of trees. Use the Eat Tree ability and get in as far as you can without revealing the path to your enemy. Once your opponent takes out your base, he will give up looking for you. For better results research Nature's Blessing and make sure you use a Tree Of Ages that you are expanding with, rather then the one your opponent is using. When you use the Eat Tree ability, remember to be very discrete so your opponent does not see it.

On the second Night Elf mission, you have to find Illidan and prevent him from taking Sargaras Eye. Just in front of the gate before him, use Blink to the other side of the gate. You can now kill Illidan and destroy the eye. Destroy the gate after that, and you will talk to someone who is not there, but Illidan's voice can be heard. Note: Tote: This is easier if you enable the iseedeadpeople and whosyourdaddy codes.

In the fourth Undead mission, The Return To Nothrend, you will find a giant penguin in the left corner on the island that you started on. Kill the guarding sea lions and destroy the tent so you can approach it. Then, kill the penguin itself. You will get a Ring Of Superiority. A normal penguin will spawn next to it. You can kill it, but it will not give you anything.

Play the Night Elf mission where you have to escort the runner. In the lower left corner in the very back of the map is a Pandaeran relaxation area. A Brewmaster is here. He will spout some gibberish and drop Slippers Of Agility.

In the fourth Night Elf mission, Wrath Of The Betrayer, at the top left side of the map is a small garden and a fountain that only Maiev can visit. Use your Blink-spell to get to it. In there, you can find a rat with the name "Grank the Rat", which has 100% Evasion and Spell Immunity.

Select the "Custom Campaign" option at the menu, then choose the "Exodus Of The Horde". The game wukk launch a screen with the selection of the first level. This extra campaign takes place after Thrall leaves Lorderon, but before Kalimdor.

In the first Undead mission, King Arthas, you can find Little Timmy from the original Warcraft 3. He is in the woods, left of the town which is northwest of the three Altars. Little Timmy will sell you some Ice Shards, which are useful both later in the game and the campaign.

In the third Human mission, where you need to escape the prison with the Blood Elves and Vashj, there are three colored sheep about in the bottom middle of the map with platforms in front of them. If you step on the platforms in order, you will come out with a "Bah Ram Ewe". Also, you can get a bonus level to defend the Portal to the Nether Land.

In the last Human mission, Lord of the Outland, where you need to assault the Lord's castle, you can find the Butcher and Wirt's other leg (from Diablo) just northwest of where you start. The Butcher will also say the same sentence, that he did in Diablo, "Fresh meat".
