These cheat codes DO NOT work on battle.net. They only work in single player mode.

Also, I took the time to put them in order of 'value'.

AllYourBaseAreBelongToUs - Instant victory

WhosYourDaddy - God mode

GreedIsGood [amount] - Gives you X Gold and Lumber

IseeDeadPeople - Remove fog of war

WarpTen - Speeds construction of buildings and units

Synergy - Disable tech tree requirements

PointBreak - Removes food limit

ThereIsNoSpoon - Unlimited Mana

As for the rest of them, I find them to be pretty crap. But if you still want them here they are!

IocainePowder - Fast Death/Decay
KeyserSoze [amount] - Gives you X Gold
LeafitToMe [amount] - Gives you X Lumber
StrengthAndHonor - No defeat
Motherland [race] [level] - level jump
SomebodySetUpUsTheBomb - Instant defeat
WhoIsJohnGalt - Enable research
SharpAndShiny - Research upgrades
RiseAndShine - Set time of day to dawn
LightsOut - Set time of day to dusk
DayLightSavings [time] - If a time is specified, time of day is set to that, otherwise time of day is alternately halted/resumed
