To enable the cheats hit ENTER while in the game, then type one of the codes, and hit ENTER again. In multiplayer games, the cheats effect both sides.

If you continuously click on your human/orc units, they will get mad and impatient with you. If you continuously click on the sheep, they will say 'ba-rim-u' and explode!

To make ANY neutral animal on the map explode, not just sheep like the person above posted, click on the animal repeatedly many times. The animal will explode and all that will remain are bones and blood. The animal's death will not harm you or the enemy units. It's just something to fill the time if you're bored.

When you are playing a mission in the Human Campaign mode, remove the Warcraft 2 CD out of your PC and replace it with a Warcraft 1 CD during gameplay. The game will play the defeat song that you usually get when you lose in Warcraft 2 during gameplay. After that song is done, the game will suddenly play improved versions some Human Campaign songs from Warcraft 1 and an improved version of one of the Orc Campaign songs from Warcraft 1.
