These are cheats that ONLY work in Single Player mode in Starcraft. If you always use cheats and never won any missions or campaigns without them, then you're a newbie. Also, its more fun without cheats sometimes.

Using cheat mode:
While playing the game, push ENTER and type one of the following codes, and press ENTER again to enable the cheat. If it works, it will display "Cheat Enabled" in the game. To disable a cheat, press enter and type the cheat again and it will display "Cheat Disabled" in the game.
