Most of the units say something humorous if you click them multiple times. 

Jimmy the Seal

Somewhere in the middle of the map (Night Elf campaign, Chapter 5) there is some mushrooms with some spiders infront. There is a seal called Jimmy behind them. Click him until he blows and a manual of health will be dropped. NOTE: Use seedeadpeople cheat to find him easier. 

Find the enemy with out cheating

If you think you beat the level but it wont say it most likely there is one more thing out there. If you press Tab the map will turn black and the enemy will turn their color. Therefore it will be easy to spot the enemy. 

EASTER EGGS 

Most of the hidden easter eggs are scattered throughout the game. Use the "iseedeadpeople" cheat code to find them. 

To reenter God mode after you have created your City, hold [Ctrl] + [Alt] + [Shift] and click the "God Mode" button. The tools will not be the post-establishment tools, but will revert back to pre-city tools. They will remain that way as long as you stay in God mode, otherwise they go back to normal.

Quick money:

Use the following trick to quickly accumulate money. 

1. Press [Ctrl]+ X

2. type weaknesspays

3. Hold [Left Shift]

4. Press [Enter]

5. Press [Cursor Up]

6. Press [Enter]

7. Repeat steps 5 and 6; you will get $1000 each time. 

Alternately, press [Ctrl] + X to display the console window. Type weaknesspays, but do not press [Enter]. Highlight the word using the mouse, then press [Ctrl] + C to copy the text. Press [Enter], then press [Ctrl] + X to open the console window again. Hold [Ctrl] and press V to paste the text, then press [Enter], without releasing [Ctrl]. Keep pressing V then [Enter] while holding [Ctrl] while the console window is still open to amass as much money as desired. 

Start a new city, enable the you don't deserve it code, then immediately place the Federal Prison, Army Base, Toxic Waste Dump and Missile Range anywhere (and nothing else). Click the "Speed Up Time" arrow and allow the game to idle for five minutes. When you return, you will have been paid big money over the years with no expenses.

Hint: Double rewards:

Enable the you don't deserve it code, and write down requirements for reward (hold the pointer over the picture.) Place that reward. Then, do the requirements for it. Neil Fairbanks will ask your permission to build the reward a second time in your city.

Hint: Unlimited rewards:

Enable the you don't deserve it code, then completely quit the game. The next time you play, enable that code again. You can do this as many times as desired.

Hint: Brainwashing:

On the adviser screen, click the query box, then click the "X" on the bad or good messages.

Hint: Abort Obliteration:

If the "Obliterate City" button under "God Mode" was accidentally clicked, anytime before the game screen starts flashing white, press [Esc]. The game will stop the obliteration sequence.
