夜精灵族快攻(BY pig_xiii) 1.2个农民采木，3个农民变人口。
2.造1个英雄，取消1个人口，人口变为11/10。
3.英雄溜出去召1个运输船，路上不要打，进运输船，再去另1处召3个兵，都进运输船，操作好的话伤不了多少血。
4.回老家补满life和mana(3各雇佣兵中有1个会heal，elf族的人口战可以补mana），全部空投到对方老家，间中可以造兵营。
这个战术是非常快的，只要造一个英雄就开打了。欢迎讨论，提高中国RTS的技术战术。

《魔兽3》ORC和HUM农民使用小技巧 (BY: chenbenyao)
用ORC或者HUM的苦工点“A”键攻击树，会把树砍倒而不采集它，可以利用这点砍出1个位置甚至1条小路来，因为塔的碰撞体积很小，可以在砍出的地方造塔，这招可以在对手的基地外围包住的树丛里砍进去1条小路，在接近他的地方（别砍穿了）造2个塔，然后你进攻他的时候会打开塔的视野，塔会射击他的农民或建筑。这招可以在龟岩，TM，GNOLL WOOD（要2个农民，树层很厚）等地图上使用。
另外在GNOLL WOOD的左上脚的石头人处，可以砍掉1堆小岩石上的1棵树，在那里造个塔，3个石头人会被塔白打到死。9及石头人有好宝可以去拿。
Animal Explosions 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.
Disable Defeat Trigger Press enter, and type in "StrengthandHonor" Without the quotes. In the bottom left hand corner, it should say "Cheat Enabled". This code Disables the defeat trigger, so you can't lose.
Easter Egg 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"
Extra scene in the ending 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.)
More Easter Eggs 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.
