Press Enter and enter the following codes:

Simply click on any neutral animal at least 25 times for it to explode, injuring any nearby units.

There are always monsters near your base. Defeat them to gain about 120 experience points.

At the intermission sequence featuring the Archmage and the Prophet, in the background are two sorceresses floating around. One of them will turn the other into a sheep.

In the human campaign when you have to defend the town from the Undead, and the last Undead campaign level when Kel'thuzad is summoning Archimonde, enable the whosyourdaddy and iseedeadpeople codes. Kill the enemy's bases. You will automatically win without the time running out.

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.

When you reach the supply limit (90 food), you cannot build any more units. However, when you build Ancient Buildings, it eliminates 1 food, thus allowing you to build more units. When you cancel your Ancient Building, you will have your 1 food supply back, getting you over the supply limit.

In campaign mode, Infernal Golems count as summoned unit (even though they do not die due to time limit). Thus, you can use magic such as Dryad Abolish Magic to kill them easier.

Start off by creating Shades as soon as the game begins. Have them at the entrance to your base and stand their ground. Since they are invisible, no one can kill them and ground units will be able to get by them. This also works with trapping Heroes. Surround a hero and he will be stuck.

Play Chapter 5 of the Night Elf campaign. Go as far right as possible in the cavern when you begin. Search for a group of mushrooms on the right side that have a skull and bone in the ground in front of it. Turn back if you hear the Priestess comment about the demon bile, as you have passed it. Use Force Of Nature on the mushrooms to open a path that is littered with bones. Bring units into the to start an intermission sequence and The Largest Panda Ever will appear and attack. Defeat it to get a Necklace Of Spell Immunity.

On Chapter 3 of the Human campaign follow the road up until you reach the bridge. When Archilles says you must find another way, go up the path to the east. Follow it up until you reach the Murlocs. Keep going up until you kill the entire band of Murlocs in that small area. You will notice only one Murloc Hut. Destroy it and you will get a Maul Of Strength.

In Chapter 1 of the Human campaign, you can save Timmy from gnolls. In Chapter 4 of the Human campaign. after your defeat the first undead town you encounter Kel Thuzad. When the intermission ends, go to the lower path and you will see a cage. Attack the cage and a ghoul will appear, but not attack. Look at the ghouls name to learn that it is the same Timmy that you saved. Kill the ghoul to get a random item.

When using the Humans in a custom or campaign game, the hero paladin carries a book of spells with him. This is what he looks at as he casts Holy Light. Zoom in fully on the book while performing the spell, and the name "SAM" can be seen. Note: Timing is important, but mainly keep watching the screen.

Play Chapter 2 of the Undead campaign. Knock down the trees in the curve in the path which leads to the Rogue Wizard. A path to the left will lead to an intermission featuring the Sasquatch and Elder Sasquatch. Note: The Elder Sasquatch will leave behind a Claws Of Attack +6.

In Chapter 5 of the Night Elves campaign, "Brother's By Blood," the first main quest's path has many mushroom trees where the river separates the land masses. In the bottom right of the land you are first on, do "Force Of Nature" on the mushrooms and send them to fight the skeletons. Move on until you see another mushroom group in the bottom right as well. Do the same spell and move onto the small circle. Then, kill the Death Revenant and Skeletons to receive the Robe Of The Magi, which gives a +6 bonus to intelligence.

Play Chapter 2 of the Undead campaign. Enable the iseedeadpeople code. Look at the left edge of the map until you find a waterfall. Have a unit go to the waterfall. You have to clear a path through the trees by attacking them. When you get to the waterfall, you will find the secret Pandaren relaxation area and see a photo of two panda bears.

Play the first mission of the Prologue. Enable the iseedeadpeople code, then look at the island at the top of the map to find some pirates guarding "phat lewt".

Successfully complete the game under the hard difficulty setting to see a 20 second clip of what StarCraft 2 characters would look like under the WarCraft 3 engine after the credits. Note: This movie is in-game, after they play "football" during the ending credits. Also note the Orc in a spacesuit during that sequence.
