Warcraft III: Battlechest Cheats

In the Undead mission, Trudging Through the Ashes, on the land where you get the shade, there is a blue barracks buildling guarded by two knights. If you manage to kill them both, destroy the barracks. After you destroy the barracks, kill all the riderless horses. One drops a Ring of Protection +2.

On chapter four ''The Cult of the Damned'' of the human campaign there is a cage in the city past the first undead encampment. If you attack it it will break open and a Undead ghoul will break out. He acts as a neutral unit. If you kill him you will get an item.

In the second Undead level, "Digging up the Dead", go south of where Uther the Lightbringer is waiting for you. You may have to kill him first, but do not pick up the urn or the level will end. Go south, and you will find a pen of four sheep. Kill them, and one carrys a Goblin Night Scope.

Go the first mission of the prologue, and use the ''iseedeadpeople'' code to reveal the map, look at the island at the top of the screen to see some pirates guarding ''phat lewt''

Human Campaign: Chapter 1

Bring Arthas to the graveyard toward the eastern edge of the map. Any villagers or sheep that you killed will appear there at night.

Human Campaign: Chapter 6

Go to the western edge of the map to find a zoo. In one of the cages is a rat with a special name. If you attack him, you will always miss, but he is a critter, so keep clicking him to blow him up and receive a Talisman of Evasion.

Again, the ''iseedeadpeople'' cheat is very useful in finding most of these.

Undead Campaign: Chapter 1

In the main town area after you get your shade, there are 2 civilians fighting with a large crowd watching. Named: Robert and Tyler. (from the movie Fight Club)

Undead Campaign: Chapter 2

After the cut scene in the middle where you find you need the urn, knock down the trees to the west of the green human base. When you bring a unit to the waterfall you see a flash of a baby panda sitting on the shoulders of another panda wearing a sword. It'll have the text written: ''SECRET FOUND Panderan Relaxation Area''

Knockdown the trees in the curve in the path which leads to the Rogue Wizard. A path to the left will lead to a cutscene with the Sasquatch and Elder Sasquatch. The elder Sasquatch leaves behind Claws of Attack +6.

Tichondrius is also on this map and will kill some humans.

Orc Campaign: Chapter 7

Your tauren units will eventually run into a large salamander named 'Hungry Hungry Lizard,' a play on an old board game 'Hungry Hungry Hippos.' He'll eat his way through a large patch of mushrooms if you watch him long enough. When he's done eating, he will pop into a splash of green goo, revealing a path that leads to a nifty item, The Lion Horn of Stormwind, which generates a protective aura around your hero.

Night Elf Campaign: Chapter 2

In the area where you get the first set of ballistas. Knock down the trees in a north easterly direction. Near the back, among the trees will be a hydralisk. Bring your hero to it to let it join your party.

Night Elf Campaign: Chapter 5

In the cavern, try and go as far right as possible when you start out. Look for a bunch of mushrooms on the right side with a skull and bone in the ground in front of it. If you hear the priestess comments about the demon bile, you've gone too far. Use force of nature on the mushroom sto clear a path. You will see the path is littered with bones. When you bring units into the path you'll get another cut scene and The Largest Panda Ever (level 10) will come to attack you. It'll leave behind a Necklace of Spell Immunity.

Extra Credits: After completing the game on hard mode and normal mode, check the credits, you'll see a parade of units while the credits roll, ending in some hydralisks coming out and kill them (not the same as the marine/hydrlisk battle listed elsewhere here)

Most of the units say something humorous if you click them multiple times.

All of these have been taken from several different posts on the message boards, then verified and edited together by myself.

To make one of the various animals in the game explode simply click on them a bunch of times and finally they will blow up in a big explosion.

Not much of anything, but just for fun. Select a unit, then, without giving it any real orders, click it again so it keeps talking. It will cycle through the three normal voice overs, and after four or five clicks, the unit will begin to say something interesting, funny, or just wierd.

Select Custom game from the Single Player menu and then double click the Senerio Folder at the top of the list that appears. 2 new maps will appear one being a Mini-Game of Called Sheep Of Death. Where you run back and forth dodgeing explosive sheep. use S to move left H to move right and esc to use a smart-bomb type attack.

If you beat the final Night Elves mission on Hard mode, there will be an extra scene in the ending that shows what several Starcraft (and an Orc in a space suit) units would look like on Warcraft 3's engine. (Note: This is NOT a scene from Starcraft 2, it is just an example of what Starcraft units would look like on WC3's engine, nothing more.)

In Chapter 3 of the Blood Elf campign
In your travels thrugh the dunguns you will encounter a large battle in the south center area of the map, if you go south of this battle and through the iron gate on the left you will see three sheep, click the platforms in front of them in this order: TOP THEN BOTTEM THEN MIDDLE, the iron get to the north will then open, pick up the question mark then beat the level normally to unlock the bonus mission called The Crossing.
For beating The Crossing completely, you'll gain access to a Pandaren Brewmaster in Chapter Four: The Search for Illidan.
