Level Skips
Three cheat codes exist to allow each of the three competing races to skip mission levels. When using the exiled Earthlings, enter the code "Terran#" to skip missions, replacing the "#" with the specific number of the mission you'd like to play. Use the same pattern for the other two races, with the codes being "Zerg#" and "Protoss#". Or you can enter the cheat code "Ophelia" to enable mission select.
Supplies
Several cheat codes allow you to replenish supplies. Entering the code "whats mine is mine" unlocks 500 crystals. The cheat code "breathe deep" provides 500 vesper gas. Using the code "show me the money" earns you 10,000 minerals and gas, while the code "food for thought" removes all supply limits.
Abilities
All three competing races need to build things throughout the game, and the cheat code "modify the phase variance" allows you to build anything, while the code "operation cwal" enables faster building. If you'd like easy upgrades, use the code "something for nothing" to get free upgrades or the code "the gathering" to receive free unit spells and abilities. And the code "medieval man" gains all research abilities.
Fighting
Entering the code "noglues" prevents the enemy from using Psionic Storm, placing them at a distinct disadvantage. The code "war aint what it used to be" eliminates the fog of war, allowing your armies to be more efficient. And typing the code "power overwhelming" makes selected combat units invincible.
Other
For an instant victory, use the code "there is no cow level". Or, if you'd prefer an instant loss, enter the code "game over man". The cheat code "staying alive" allows you to keep playing even after a win. If you'd like a better view of the conflict, use the code "black sheep wall" to reveal the entire map. And finally, the cheat code "radio free Zerg" prompts the Zerg Overmind to sing a hidden song.
